City Cell Vs Plant Cell Essay

City Cell Vs Plant Cell Essay
There are many different ways in which a cell can be compared to something else. You can compare a cell to a factory, a school, or even a city. When
comparing a cell to a city each organelle acts as different part of the city. One example of an organelle comparing to a part of a city is the cell
membrane. The cell membrane can be compared to the boundaries of a city. Just like how the cell membrane keeps all of the organelles inside, the
boundaries of a city determine what is or is not within city limits. In a city the most important building is the city hall. This is where all city's
government officials work. City hall is very much like the nucleus in a cell. The nucleus holds and protects all the cell's genetic information just like
how city hall holds all the records...show more content...
Just like the ribosomes factory workers are responsible for building and producing items that the city needs. Next is the endoplasmic reticulum
which is what molecules inside the cell travel along. This obviously compares to the roads which people in a city travel along to get from place to
place. In a plant cell there is a "reservoir" that stores water for that it might need later. City's need to store water too and to do this they use water
towers. These two are almost exact because they both only have one responsibility which is to just store water for later usage. Now although their
are many other organelles in a cell these are just a few that can relate well to the different parts of a city. Cells are a huge part of biology and even
though we just compare them to different things in a city just to get a better understanding of what they do, a cell itself really is just like one tiny
city inside our bodies. Because without every organelles doing its job we wouldn't be able to function the way we do. And the same is with a city in
real life. If every part of the city isn't running smoothly then it just wouldn't be able to work

Functions Of Function Of Cells Essay
Introduction
All living organisms are composed of very important building blocks called cells. Cells are composed of genomes that identify an organism's traits
found in the cell's nucleus. In plants, genomes are found in chloroplasts. Cells are continuously working to reproduce new identical cells during a
process called, Mitosis. This progression consists of two phases; Interphase and the Mitotic Phase. Mitosis consists of four major phases; Prophase,
Metaphase, Anaphase, and Telophase. Towards the end of the four phases, DNA has been duplicated and divided during a process called, Cytokinesis
which occurs in the mitotic phase. Not only does this cell cycle occur in both plants and animals but also includes prokaryotes such as bacteria.
Bacteria, however, does not have a membrane surrounding its DNA, therefore it does not go through mitosis like plants and animals but through a
process called, binary fission (Hay). Slightly different process yielding the same end results (O'Grady and Cashmore, 107).
Interphase, also known as the, "resting stage" is the key phase of the cell cycle. This is where normal cell function and cell preparation begin. Cells
will spend approximately 16 to 18 hours in this phase (Hay). It is sectioned into 3 phases: Gap 1 (G1), Synthesis (S), and Gap 2 (G2). During the Gap
1 phase, the cell resumes normal cell functions and growth. During the Synthesis phase, the chromosomes are replicated and sister chromatids are
formed. During the Gap 2 phase,

Cell Theory
1.Cell Theory is an explanation that says everything is made of cells. It continues on to say that those cells came from preexisting cells. Cell Theory is
a theory because it is a frame–worked explanation of an observation made by many biologists like Anar Van Leeuwenhoek. Van Leeuwenoek studied
plant stems, pond water, and gathered a conclusion that generally, all of those things are made of cells. Other biologists like Louis Pasteur added onto
this idea that all organisms are composed of cells. Atheory is also composed of two components; a sequence of patterns in the world and the thing or
catalyst that is responsible for the pattern. The sequence of the pattern in Cell theory is that every organism in the world are made up of cells....show

The fatal flaw in my experiment of cloning a single plant, creating a population of 100 plants that are genetically identical, and raising these plants in
identical environments with no variation in traits is that there is no variation to show any difference(s) in the experiment.
3.A salt crystal dropped into a beaker of water becomes smaller and eventually seems to disappear. However, the same salt crystal remains intact at
the bottom of a beaker of octane because Sodium Chloride is ionic and would get attracted to the water. The octane is hydrophobic and has nothing for
the salt crystal to bond with. The water is polar and hydrophobic, which gives the salt the ability for the oxygen atoms in the water to be attracted to the
Sodium ion, and the hydrogen atoms to the chloride ion.
4.Molecules with carbon–carbon bonds have more potential energy and lower entropy than carbon dioxide because the carbon to carbon bonds are
held together loosely. Because the carbon to carbon bonds are held loosely together, the bond has low entropy, high potential energy, and more usable
energy. The Carbon dioxide is held tightly together, has high entropy, and will have low potential energy because the charges will be attracted to the
oxygen. This results in the carbon dioxide to have less usable

Stem Cell Research : Stem Cells
Stem Cells Stem cells are cells that are found throughout the human body. They reproduce over a long period of time without changing. Stem cells
can produce specialized cells, such as brain, muscle or lung cells. Stem cells in the last few years have recently made a big debut because medical
professionals have discovered so many unique qualities to stem cells. They are on the cutting edge of medicine because of all their uses and the
qualities that make them so unique from any other cell in the body. Stem cells have the power to make so many breakthroughs in the medical world.
Medical researchers have all ready found so many ways that stem cells can be used for the better of so many people. Genes play an important role in
determining what genetic traits or mutations we receive. Researching stem cells can help determine this. Stem cell research is useful for learning many
things about human development and about how the body has the power to repair itself. Researchers are finding new ways each day that stem cells
can be used and the possibilities that they find for stem cells could be endless. A few ways they can be used to treat diseases, be used as graphs for
burn victims or surgical use, and even to correct birth defects. The pros of stem cells are limitless.
Stem Cells have recently have caught the eye of many medical professionals because of their unique properties, so what exactly are Stem Cells? Stem

The Theory Of The Cell Theory Essay
Introduction
The cell theory is composed of three ideas from three different German scientists. In 1838, scientist Mattias Schlieden said that all plants were made
from cells. One year later in 1839, scientist Theodor Schwann said that all animals were made from cells. In 1855, scientist Rudolf Virchow said that
all cells come from other cells. These three ideas were put together to form the cell theory. The cell theory states that all living things are made of cells,
cells are the basic units of structure and function in living things, and all cells are produced from other cells (McGinnis, 2011).
Prokaryotic cells are the simplest systems that exhibit all of the signs of life. They reproduce by binary fission, a process where the DNA is
duplicated and the cell splits in two. They are the smallest types of cell, and have a large array of abilities. Some prokaryotes live in the absence of
oxygen, some in extreme cold or heat, and some at the bottoms of oceans. These extremist prokaryotes are known as archaebacteria. The most common
prokaryotes are eubacteria, and are found nearly everywhere on Earth (Blamire, 2001).
Prokaryotic cells can vary in their structure depending on where they reside, but all prokaryotic cells have certain features in common. All
prokaryotic cells have a cell wall; a cell wall gives structure and shape to the cell while providing a place for the flagella to anchor. They have a plasma
membrane, which is just inside the cell and serves as a

An Introduction Of Cell Biology
Introduction to Cell Biology
A Cell is the smallest structural and functional unit of an organism and consists of cytoplasm and a nucleus enclosed in a membrane
A Prokaryotic Cell are cells without a membrane–bound nucleus. An example of a prokaryotic cell is bacteria.
A Eukaryotic Cell does have a membrane–bound nucleus, making it different from a Prokaryotic Cell. The Nucleus contains genetic material and is
surrounded by a nuclear envelope. An example is an animal cell.
Both types of cells contain organelles, each with a specific function. Plant and animals cells both contain a nucleus, cell membrane, cytoplasm and
mitochondria. What defines the two cells is the plant cell also contains a rigid cell wall, a permanent vacuole and chloroplasts. The Nucleus contains
genetic material and controls how the cell operates. The Cell surface membrane, or plasma, surrounds the cell and controls what enters and leaves.
Membranes are said to divide up the cytoplasm of eukaryotic cells. The Cytoskeleton, which is made up of microtubules and microfilaments, moves the
cytoplasm during cell migrations. Mitochondria is where aerobic respiration is performed. Protein synthesis happens in the Ribosomes. In terms of the
plant cell, the Rigid Cell Wall strengthens the cell and helps maintain the structure. The Chloroplasts contain chlorophyll, which absorbs light for a
plant to perform photosynthesis. The Permanent Vacuole is filled with sap and keeps the cell turgid.
A Eukaryotic cell has

Eukaryotic Cells Essay
Eukaryotic Cells The cell may be regarded as the basic unit of an organism, it carries out the essential processes that make the organism a living entity.
All cells share certain structural and functional features and they are of almost universal occurrence in living organisms. Biologists have devoted a
great deal of attention to its structure and the processes that go on inside it. They have recognised a major distinction between two types of cells,
Eukaryotic cells that have a nucleus and Prokaryotic cells that do not have a nucleus. There are many other differences between these two cells, in
particular eukaryotic cells have a full complement of membrane...show more content...
The formation of the proteins and phospholipids is called the lipid bylayer. The proteins take the form of globules dotted about in a mosaic pattern with
some being attached to the urface of the membrane while others penetrate into it to varying extents. Some of these proteins act as enzyme catalysing
chemical reactions within the membrane and also as pumps and channels transporting molecules into and out of the cell. The plasma membrane is
perforated by pores and allows substances to pass in and out of the cell by Diffusion Active Transport, osmosis, Endocytosis and Exocytosis. The
external cell membrane contains lipids and proteins combined with sugar molecules called Glycolipids and Glycoproteins. The sugar molecules only
attach to the outside of the cell membrane and form what is known as the Glycocalyx or cell coat. The Glycocalyx is sticky and enables animal cells
to adhere to each other. In the development of organisms cells must migrate from one region to another and recognise what kind of cells are their
proper neighbours and what kinds are not. This recognition ability appears to lie within the Glycocalyx.
The endoplasmic reticulum is found in the cytoplasm of the cell and like the plasma membrane is composed of phospholipids and protein. ER is an
intracellular transport system moving materials from one

Explain Why A Cell Is Like A City
A Cell is like a City A cell membrane regulates what enters and leaves the cell. It is like a gate in a city because it regulates who comes in and goes
out of the city. A nucleus is the control center of the cell. It is like a police department because the police control how everyone and everything acts. A
ribosome synthesizes proteins for the cell. A ribosome is like a factory that produces stuff for construction workers. The ER synthesizes lipid
membranes and proteins and transports stuff. It is like a manufacturing plant because it makes stuff just like the ER. The golgi packages and modifies
proteins. The golgi is like Post Office because the post office packages mail and sends it places. The lysosome digests and gets rid of wastes. It

Cancer Stem-Cell Theory Essay
The cancer stem cell theory hypothesizes that tumors or cancers arise from mutations or epigenetic changes in normal stem cells. These mutated or
genetically altered stem cells possess the properties of the normal stem cells such as the ability to self–renew, differentiate into any type of body cell,
and resist apoptosis. Hence, the cancer stem cells (CSC) are named so. It is also suggested that because of the above–mentioned properties of the cancer
stem cells, the current anti–cancer therapies are not entirely successful (Gil et al, 2008). Despite surgery and other therapies, even if very few of these
cancer stem cells survive, they can continue to act as a source for more tumors, even though the therapies eliminate all visible signs...show more

Some strategies that can be used to target the cancer stem cells:
1)Stem cells possess markers that are different from the differentiated cells. One method can be to develop treatments that target only the cancer stem
cells and not the healthy differentiated cells.
2)Investigate to find markers that distinguish between cancer stem cells and healthy stem cells.
3)Prevent self–renewal of the stem cells within the tumor mass: Targeting proteins that regulate the cell cycle in the cells of the tumor mass can be a
potential strategy to prevent the self–renewal of the cancer stem cells. Bao et al (2006) reported that proteins involved in regulating cell cycle,
especially at the checkpoints play an important role in determining the CSC resistance to radiotherapy. This is because radiotherapy leads toDNA
damage, which activates the checkpoint proteins and increases their expression. In vivo and in vitro studies have shown that inhibition of checkpoint
proteins such as Chk1 and Chk2 decrease the radiotherapy resistance ability of the brain stem cells that were previously radiotherapy resistant (Gil et
al, 2008). This strategy coupled with radiotherapy and/or elimination of the tumor mass by surgery can potentially prevent relapse of cancer.
Tumor progression or cancer development in humans takes decades to develop because this process requires multiple insults like mutations and
epigenetic changes in the DNA. These changes

Essay about The Cell
The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa;
others, such as nerve, liver, and muscle cells, are specialized components of multi–cellular organisms. Cells range in size from the smallest bacteria–like
mycoplasmas, which are 0.1 micrometer in diameter, to the egg yolks of ostriches, which are about 8 cm (about 3 in) in diameter. Although they may
differ widely in appearance and function, all cells have a surrounding membrane and an internal, water–rich substance called the cytoplasm, the
composition of which differs significantly from the external environment of the cell. Within the cell is genetic material, deoxyribonucleic acid...show

All cells are dynamic at some stage of their life cycle, in the sense that they use energy to perform a variety of cell functions: movement, growth,
maintenance and repair of cell structure, reproduction of the cell, and manufacture of specialized cell products such as enzymes and hormones. These
functions are also the result of interactions of organic molecules.
Plasma Membrane
The plasma membrane, a continuous double layer of phospholipid molecules 75 to 100 angstroms thick, constitutes the boundary between the cell and
its external environment. In addition to lipids, the plasma membrane has protein components (polypeptides) that are associated with either the outer or
inner surfaces of its layers or are buried within them. The structure as a whole is selectively permeable, or semipermeable; that is, it permits the
exchange of water and selected atoms and molecules between the cell exterior and interior. This is vital to the cell because while the plasma membrane
helps maintain high local concentrations of organic molecules within the cell, it also allows interaction between the cell and its external environment.
The plasma membrane mediates such interactions in various ways. The exchange of mineral ions and small nutrient molecules is controlled by plasma
membrane proteins that act as pumps, carriers, and channels. The plasma membrane also participates in the exchange of larger molecules through
phagocytosis, the

Eukaryotic Cell Lab Report
With the use of a light microscope and an electron microscope, scientists discovered that organelles in a eukaryotic cell do not actually float around
freely. They discovered the cytoskeleton, which is key towards a cell's structure and activity. (112) It is extremely dynamic and important for the
cells, as provides a secure hold on many organelles and cytosolic enzyme molecules. In addition, it can bend the plasma membrane inward to form
either food or other phagocytic vesicles. It is also involved with cell motility with its interaction with motor proteins. This correlates towards
movements and changes in a cell's location. This is the result of the cytoskeleton working with motor proteins by using it as "feet" to walk to a different
location. It is a network of fibers that is composed of microtubules, microfilaments, and intermediate filaments. (113) Out of the fibers it is composed
of, microtubules are the thickest, microfilaments are the thinnest and intermediate filaments are diameters in a middle range. Microfilaments maintains
cell shape, changes in shape, muscle contraction, cytoplasmic streaming, cell motility and division for animal cells. (113) Microfilaments are made
through a twisted double chain...show more content...
Within the plasma membrane, they form a 3D network to support the cell's shape. (Chapter 6 slide) Therefore, it helps support the cell shape with
this network by keeping the organelles in place and then assists in its movement. In addition, its direct role is to bear tension via pulling forces. This
whole network gives the cortex (outer cytoplasmic layer) a semisolid form rather than a fluidity structure. In addition, in some animal cells the
microfilament make up the core of microvilli that increase a cell's surface area. (117) Therefore, this filament is essential towards maintenance of cell
shapes as it helps support it and, in some cases, make up the surface

Plant cells have many different parts that are need to work together and function as a whole. These parts are the cell membrane which can be compared
to a "Condom" due to the fact that is a very thin protective layer that lets certain substances to pass through. Cell wall is a thicker rougher membrane,
which gives the plant most of its structure and support, the cell wall also bond with other cell walls to form the structure of the plant. Centrosome may

Lysosome also called vesicles sphere shaped organelles surrounded by a membrane, contain digestive enzymes. This is where the digestion of nutrients
takes place. Mitochondrion is a sphere shaped rod like organelles with two membrane, the mitochondrion converts the

The cytoskeleton is the most important organelle. Without it in place, all the other organelles inside the cell would be randomly floating around with
no sense of order. This would make the cell's job much harder and could create multiple different outcomes, since the cells would not have the same
organelles in the same areas. The cytoskeleton keeps all the other organelles in the cell and in the proper areas. The cytoskeleton also anchors the cell to
its neighboring cell and to the protein network in which that cell is sitting. This organelle provides the cells shape, which also provides the function of
that particular cell. The cytoskeleton additionally allows the cells to shrink and grow very quickly.
Another function is the assisting of moving materials in and out of the cell. The cytoskeleton facilitates movement through three main components
which are microfilaments,...show more content...
The cytoskeleton has a very dynamic nature, because it is necessary for cells to change shape and complete cell division, or migrate. In cell division,
the cytoskeleton plays an essential role in equally distributing the chromosomes into each of the new cells. Each of these self–assembling proteins has
"critical concentration," a characteristic concentration. In which, below is the monomer state and then above is the polymer state. The concentration
favors the building up of filament, and decreasing the filament deconstruction. The allows the cell to quickly control the cytoskeleton structure.
One third that makes up the cytoskeleton are microfilaments. These are also commonly called actin filaments. These are filamentous structures which
are in the cytoplasm of eukaryotic cells and form part of the cytoskeleton. When they are in cells which are modified by and also interact with multiple

The cytoplasm is the area between the nucleus and the cell membrane. The cytoplasm contains many important structures. This area is basically the
main place where you will find structures that help the cells stay alive.
Mitochondrion is an importance structure that lies in the cytoplasm area. Mitochondrion is the plural word for mitochondria, which is the key
organelle that converts energy from one form to another. Mitochondria changes the chemical energy stored in food into compounds that are more

To complete this we had to make wet–mount slides and
observe them under a light microscope. To prepare a wet–mount
slide you must first obtain your specimen you are going to look
at. You then put the specimen on a clean glass slide in the
middle. Next, you take a medicine dropper and place one drop of
water on the specimen. After that, you hold a clean coverslip
and place the bottom edge of the coverslip in the drop of water.
Next, slowly lower the rest of the coverslip so that there are no
air bubbles, onto the remaining part of the specimen. By putting
specimens into wet–mount slides it saves a lot of time and energy
instead of putting them into set slides. Also, a wet–mount slide
can be cleaned and re–used.
We put onion cells, cheek cells, and Elodeo cells into wet–

Cell Biology : An Introduction Of The Cell
Cell Biology
An introduction to the cell
The cell is the smallest unit able to sustain life, and they are often referred to as the building blocks of life. There are two primary types of cell,
which are categorized according to the way their genetic material is packaged, rather than size or shape. These are:
1.Prokaryote cells – bacteria and archeans. They are single celled organisms, where the DNA is not separate from the cytoplasm. These prokaryote cells
formed the earliest and most primitive life on earth.
2.Eukaryotic cells – found in animals, plants and fungi. In eukaryotic cells, the DNA is sectioned off from the cytoplasm in its own membrane
compartment called the nucleus.
Cells share many common features but have adapted over billions of years in a wide array of environments, to provide a variety of functional roles.
The structures and functions of a cell.
In order for cells and organisms to "live" they need to perform certain tasks such as produce energy through respiration, send messages, maintenance
and reproduction. To enable the cell to do so, it contains within small structures called organelles, eachorganelle is different and carries out a specific
