Cell theory
Cell theory is one of the foundations of cell biology and describes the basic properties of cells. It states that (1) all living things are made of cells, (2) new cells are produced from existing cells, and (3) cells are the basic units of structure and function in living things. Evidence for cell theory includes the observation of cells under microscopes, the process of cell division to produce new cells, and the ability of single cells to carry out all life functions. Unicellular organisms demonstrate that single cells can perform all life processes such as movement, respiration, sensitivity, growth, reproduction, excretion, nutrition, and homeostasis.
Cell as the basic unit of life
Cells are the basic and smallest unit of life. A microscope is needed to see cells because they are so tiny. A microscope has lenses, clips, and a stage to hold samples, as well as focus knobs, to magnify cells and their structures, like the nucleus, cell membrane, and cytoplasm in cheek and onion cells. Different plant cells like onion cells have additional structures, such as a cell wall, chloroplasts, and vacuoles.

The document is an interactive scale model of the universe that shows the vast sizes between different astronomical objects. It begins by showing the relative sizes of everyday objects like cells and grains of sand. It then expands the scale all the way out to the largest known structures like galaxy superclusters and the observable universe. The scale demonstrates how small humans and Earth are in the context of the immense cosmos.
Cell the unit of life
The document discusses cells and their classification. It states that cells are the fundamental unit of all organisms, and that organisms can be either unicellular or multicellular. It provides background on early scientists like Hooke, Leeuwenhoek, and Schleiden who observed and described cells. It also distinguishes between prokaryotic and eukaryotic cells, giving bacteria as an example of prokaryotes and noting some of their distinguishing characteristics.
3. cellular basis of life
The document discusses the history and key discoveries related to cells. It notes that the average human is composed of 100 trillion cells, each with 10,000 times as many molecules as stars in the Milky Way. Key findings include Hooke discovering cells in 1665, van Leuwenhoek observing single-celled organisms in 1673, and the development of the cell theory between 1838-1858 establishing cells as the basic unit of life. Modern microscopy has advanced understanding of cellular structures and diversity.

This document provides information about cell structure and organization. It begins by defining organelles and listing the organelles found in animal and plant cells. It then describes the structure and function of several key organelles, including the nucleus, mitochondria, chloroplasts, Golgi apparatus, lysosomes, endoplasmic reticulum, ribosomes, and vacuoles. It also discusses non-organelles like the plasma membrane, cell wall, and cytoplasm. The document concludes by contrasting the similarities and differences between animal and plant cells, and explaining how cellular organization allows unicellular and multicellular organisms to carry out basic life processes.
Mitosis ppt
Mitosis is the process by which a cell nucleus divides to form two daughter nuclei. In animals, mitosis results in two identical daughter cells. In plants, mitosis is followed by cytokinesis which divides the cytoplasm and cell membrane, resulting in two new daughter cells each with their own nucleus. The key differences are that plant cell mitosis is closed, occurring within the cell wall, while animal cell mitosis is open, dividing the cytoplasm between the two new cells.

Teaching science using concept maps
Concept mapping was developed by Joseph D. Novak in 1960s.
Concept map is a visual illustration displaying the organization of concepts and outlining the relationship among or between these concepts. (Hoffman and Novak 2003)
Teaching methods
The document describes various language teaching methods including Grammar Translation (GT), Direct Method (DM), and Audio-Lingual Method (ALM). GT was one of the earliest methods and focused on translating between the first and second languages. DM arose in response to GT and emphasized using the second language in the classroom without translation. ALM was influenced by behaviorism psychology and structural linguistics, treating language learning as habit formation through repetition and reinforcement. It aimed to avoid interference from the first language.
Concept Mapping
Concept mapping allows nurses to organize patient data, relate different pieces of information, and improve critical thinking skills. It is a visual tool that links nursing theory to practice. Developing a concept map requires the nurse to determine what is known about the patient and what still needs to be learned in order to provide care.
Introduction to Concept Mapping
This document introduces concept mapping and provides examples of its uses and methods. Concept mapping can be used for note-taking, studying, and memorization. It allows users to visually map connections between concepts, theories, and examples using paper, whiteboards, or software. The document offers tips on creating maps, such as considering the audience, using size, color, and labels effectively, and enabling zooming and collaboration functions. Other methods for presenting concepts, like free writing, lists, tables, and multimedia are also briefly mentioned.
The effects of hypotonic, hypertonic and isotonic
This document discusses the effects of hypotonic, hypertonic, and isotonic solutions on animal and plant cells. In an isotonic solution, water diffuses into and out of the cell at equal rates, maintaining the cell's normal shape. In a hypotonic solution, water enters the cell by osmosis, causing it to swell and potentially burst. In a hypertonic solution, water leaves the cell by osmosis, causing it to shrink or become plasmolyzed. Food preservation uses hypertonic solutions of salt or vinegar to dehydrate tissues and prevent microbial growth.
Specialized Cells, Biology
Specialized cells in plants and animals have unique structures and functions. The document discusses several types of specialized cells including red blood cells, white blood cells, nerve cells, muscle cells, sperm cells, egg cells, root hair cells, palisade cells, and xylem cells. Red blood cells carry oxygen throughout the body while white blood cells protect the body by killing bacteria. Nerve cells carry electrical signals and coordinate functions. Muscle cells allow movement by contracting. Sperm and egg cells are reproductive cells that combine during fertilization. Root hair cells absorb water and minerals in plant roots. Palisade cells contain chloroplasts to perform photosynthesis. Xylem cells transport water and provide structure in plant stems.

It discusses how cells are the basic unit of structure and function in living things according to cell theory. The key components and functions of plant and animal cells are described, including the cell membrane, nucleus, mitochondria, chloroplasts, vacuoles, endoplasmic reticulum, and golgi bodies. Mechanisms of movement across the cell membrane such as diffusion, osmosis, active transport, and facilitated diffusion are also summarized.
IB Biology 1.1 Slides: Introduction to Cells
1. Cells are the basic unit of all living things. Robert Hooke first observed cells in 1665 using a microscope. The cell theory states that all living things are made of cells, cells come only from pre-existing cells, and cells contain the basic components necessary for life.
2. Cells vary in size but have limitations based on their surface area to volume ratio. As cells increase in size, their ability to exchange materials decreases. Multicellular organisms overcome this through specialized tissues, organs and circulatory systems.
3. Cells carry out the basic functions of life including metabolism, reproduction, homeostasis, growth, response to stimuli, waste removal and nutrition. Unicellular organisms carry out all life functions
Easy Learning BIO part 1
This document provides information about cell components and their functions. It describes the key organelles in animal and plant cells, including the nucleus, mitochondria, chloroplasts, cell membrane, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles and cell walls. It explains that cells grow and differentiate in multicellular organisms to specialize and efficiently carry out different functions. Organization occurs at the cellular level to enable life processes. The document aims to help students learn about cell structure and the basic unit of life.
Cell Organelles: PLP
Medical school professors have identified a protein involved in cancer growth and the spread of Ebola. This protein is involved in recycling damaged components in lysosomes, which cancer and virus-infected cells rely on for survival due to their fast growth and division rates.
The document then provides information on the basic organizational levels of complexity in living things and the differences between prokaryotic and eukaryotic cells. It proceeds to label and describe the functions of various eukaryotic cell organelles, including the nucleus, ribosomes, endoplasmic reticulum, Golgi apparatus, plasma membrane, mitochondria, chloroplasts, vacuoles, and lysosomes.

Cell is the Basic Unit of Life
The word cell is derived from the Latin word “cellula” which means “a little room”
It was the British botanist Robert Hooke who, in 1664, while examining a slice of bottle cork under a microscope, found its structure resembling the box-like living quarters of the monks in a monastery, and coined the word “cells”
Plant Cell Structures
This document discusses various structures found in plant and animal cells. It provides descriptions of 20 different cell structures found in animal cells such as the nuclear pore, chromatin, nucleolus, nuclear envelope, and centrioles. It also describes cell structures found in plant cells like the cell wall, chloroplasts, vacuoles, and mitochondria. The functions of various organelles are explained, including the Golgi body which processes proteins and lipids, and peroxisomes which contain enzymes to break down hydrogen peroxide. The document provides a detailed overview of the key components of both animal and plant cells.
Investigating Cells
This document summarizes key concepts about investigating cells using microscopes and the process of diffusion and osmosis. It describes the major parts of light microscopes and how to properly use one. It explains that diffusion is the passive movement of molecules from an area of high concentration to low concentration. Osmosis is a type of diffusion where water moves through a selectively permeable membrane from high to low concentration. The document compares how animal and plant cells are affected by osmosis, becoming turgid when gaining water and plasmolyzed when losing water.

FUNDAMENTAL UNIT OF LIFE PART 2.pptx
The document discusses the fundamental components and structure of cells. It explains that cells contain organelles like the plasma membrane, nucleus, and cytoplasm. The plasma membrane is selectively permeable and allows movement of substances in and out of the cell through diffusion and osmosis. Osmosis is the movement of water across the plasma membrane from high to low concentration areas until equilibrium is reached. Solutions can be hypotonic, isotonic, or hypertonic depending on their concentration of water compared to the cell. Plant cells also contain a cell wall that provides structure and allows the cell to withstand changes in water concentration without bursting.
Cell the unit of life
The document discusses the cell, which is considered the fundamental unit of life. It describes key discoveries in cell biology from Hooke's observation of cells in 1665 to the formulation of the cell theory in 1838. The cell theory states that all living things are made up of cells, cells are the basic functional units of life, and new cells develop from existing cells. The document then discusses various types of cell structures, including the cell membrane, nucleus, organelles, and differences between unicellular and multicellular organisms. It provides details on cell transport mechanisms like diffusion and osmosis.

Electrical Functions Of Plant And Animal Cells
Plant and animal cells share some key similarities but also have important differences. Both contain a nucleus that houses genetic material and controls cell functions. They also have ribosomes that produce proteins. However, plant cells contain chloroplasts for photosynthesis and a cell wall for structure and shape, while animal cells do not. The presence of chloroplasts allows plant cells to produce their own food via photosynthesis.

ACfE Lesson Presentation
This document provides instructions for student groups to create presentations on different topics related to German culture. It outlines the key elements that make for a good presentation such as an introduction, conclusion, multiple slides per person, images, graphs, and both text and speaking. Students are asked to determine what content from their reading they will cover, additional information needed, and who will be responsible for each part of the project. The goal is for students to gain confidence through public speaking, learn effective collaboration skills, and increase their understanding of international topics and responsible citizenship.
Population Dynamics
This document discusses population dynamics and factors that affect population sizes. It covers monitoring wild populations and how succession leads to climax plant communities. Density-independent factors like temperature and rainfall can influence populations. Density-dependent factors such as disease, food supply, predation, and competition also impact population change. Monitoring is important to understand wild population fluctuations over time. Succession describes the process by which pioneer species are replaced by later species until a climax community establishes.
Density Worksheet
This document discusses whether population growth is density dependent or independent. Density dependent population growth means mortality increases with higher population densities, while density independent growth means mortality remains the same regardless of population density. The document suggests plotting mortality rates against population densities to determine which pattern applies and explains the relationship.
Physiological Homeostasis
The document discusses several physiological homeostasis mechanisms in the human body including water regulation, blood sugar control, and temperature regulation. It explains that negative feedback loops involving key organs like the hypothalamus and hormones help maintain conditions within tolerable limits. Diagrams and processes of osmoregulation, blood sugar regulation, and temperature control through endothermic and ectothermic responses are presented along with examples of homeostasis breakdown under extreme and prolonged conditions.
Environmental Influences
The document discusses how various environmental factors like chemicals, light, and drugs can affect plant and animal growth. It specifically mentions:
1) Plants need macroelements like nitrogen, phosphorus, potassium, and magnesium to grow, and can show deficiency symptoms without these. Water culture experiments are used to study these deficiencies.
2) Light is important for plant growth processes like photosynthesis and also affects flowering times in long-day and short-day plants.
3) Drugs and chemicals like lead, alcohol, nicotine, and thalidomide can harm fetal development in humans if the mother is exposed during pregnancy. Vitamin D deficiency can also affect humans.
Reprogramming Microbes
The document discusses using genetic engineering to produce human insulin in bacteria. It describes how the human insulin gene is inserted into a bacterial plasmid, which is then placed into bacterial cells. The bacterial cells grow and multiply, producing more plasmids and insulin. The human insulin is then collected and purified from the bacterial cells.
Problems & Profit With Waste
Sewage contains organic waste that provides food for bacteria. The bacteria multiply and consume oxygen in the water, causing other aquatic organisms to suffocate due to lack of oxygen. Sewage treatment uses microbes to convert harmful materials in sewage into harmless products through processes like activated sludge digestion and anaerobic sedimentation, allowing the treated waste to be safely released into rivers.
Living Factories
The document discusses biotechnology and fermentation processes using yeast and bacteria. It defines biotechnology and provides examples of yeast cell characteristics and respiration. Fermentation is described as the process by which yeast respires anaerobically by converting glucose into carbon dioxide, alcohol and energy without oxygen. Common applications of fermentation mentioned include bread making, wine making, brewing and dairy fermentation.
Genetics And Society
Selective breeding by gamekeepers in the 1800s led to the development of new dog breeds. Gamekeepers needed dogs that were large, quick, and strong to chase poachers. They bred mastiffs with bulldogs, creating the bullmastiff breed which had the desired qualities. Humans have changed dogs' appearances and behaviors through selectively breeding dogs with certain traits together over many generations. Selective breeding is when humans influence evolution by choosing which animals to breed based on desirable characteristics.
What Is Inheritance
The document discusses inheritance and genetics. It defines key terms like genotype, phenotype, homozygous, heterozygous, and dominant and recessive alleles. It explains that chromosomes contain DNA and are passed from parents to offspring, determining characteristics. Offspring get one set of chromosomes from each parent through fertilization, forming a zygote with a full set from the species. Genes located on chromosomes control inherited traits and can be dominant or recessive.
A) Variation
An alien visiting Earth for the first time would see many differences between humans. While all members of a species are similar, there are two types of variation between individuals - discontinuous and continuous. Discontinuous variation results in distinct characteristics like blood type, while continuous variation shows a range of differences like height. The type of variation determines how the data can be represented graphically.
A) Variation
An alien visiting Earth for the first time would see many differences between humans. While all members of a species are similar, there is also variation between individuals in features like height, number of petals on a flower, or heart rate. Variation can be either discontinuous, where traits fall into distinct groups, or continuous, where traits show a range of differences. Examples of discontinuous human variations include blood type and ability to roll one's tongue, while continuous variations include height and heart rate.
D) Changing Levels Of Performance
The document discusses the physiological changes that occur in the body during periods of increased activity or exercise. It explains the processes of aerobic and anaerobic respiration, including the equations for each. It also describes what happens when oxygen is not available for aerobic respiration, the effect of lactic acid buildup in muscles, and the concept of oxygen debt. The notes section indicates the document is intended to help explain to charity runners the initial effects of exercise on breathing and heart rate, muscle fatigue and soreness after training, and how sustained training can improve the heart, lungs, and recovery over time.
Co Ordination
The document discusses several body systems and their coordination to allow for movement and response to the environment. It explains that the digestive, circulatory, and respiratory systems provide energy for muscle movement. It also discusses the sensory and nervous systems, describing how sensory organs detect information, the central nervous system processes it, and effectors produce responses through muscles and glands. The reflex arc is depicted and described as the basic process by which a stimulus leads to an automatic response.
