Cell :Structure & Functions for Medical and Health allied StudentsRajendra Dev Bhatt
The cell is the basic structural and functional unit of all known living organisms.
It is the smallest unit of life that is classified as a living thing, and is often called the building block of life.
Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles. Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall. This feature was lost in the distant past by the single-celled organisms that gave rise to the kingdom Animalia. Most cells, both animal and plant, range in size between 1 and 100 micrometers and are thus visible only with the aid of a microscope.
All living organisms are made of cells and cellular products. The cell is the smallest structural, functional, and biological unit of all living organisms. It can capable of biosynthesis, replication and energy transformation. All cellular organelles carry out specific functions that are necessary for the normal functioning of the cell. Animal cells work together and function interdependently. Human cells vary in size, shape, and function. Most animal cells are so small they can only be seen with the aid of a microscope. Based on function, there are more than 200 different kinds of animal cells that help each system contribute to the homeostasis of the entire body. Despite their many differences, human cells have several similar structural features: a cell membrane, a nucleus, and cytoplasm and cell organelles.

Cells are the basis of life—the basic structural unit of living things. Molecules such as water and amino acids are not alive but cells are! All life is comprised of cells of one type or another.
One of the hallmarks of living systems is the ability to maintain homeostasis, or a relatively constant internal state. The cell is the first level of complexity able to maintain homeostasis, and it is the unique structure of the cell that enables this critical function.
In this section of the course, you will learn about the cell and all the parts that make it functional. You will also focus on the cell membrane, which is the structure that surrounds the cell and separates its internal environment from the external environment. It is a critical component because it controls what can enter and exit the cell. This section will also describe how cells reproduce to maintain homeostasis.Cells are the basis of life—the basic structural unit of living things.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
The Art Pastor's Guide to Sabbath | Steve ThomasonSteve Thomason
What is the purpose of the Sabbath Law in the Torah. It is interesting to compare how the context of the law shifts from Exodus to Deuteronomy. Who gets to rest, and why?
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
3. It is a basic living structural and functional unit of body.
The cell can be studied under two major parts- cell membrane &
cell organelles.
The living cells are made up of a substance called protoplasm,
which is slightly opaque, colorless & soft jelly like substance
consisting of water and large no. of substances in solution or
suspension.
Protoplasm within the cell and outside the nucleus is called
cytoplasm.
4. Outermost layer consist of cytoplasmic membrane.
It consist of bio-molecular layer of lipid molecule, coated
with a protein layer on each surface.
It is composed of various layers.
It has small pores and acts as selective sieve through which
certain substances are allowed to enter into the cell and the
transport outside the cell few other substances in the form
of excretion.
5. It has active transport processes across the cell membrane.
Lipids mainly are phospholipids, cholesterol and glycolipids.
Also some carbohydrates are involved in the cell membrane.
Approximate composition is as follows
Proteins 55 %
Phospholipids 25 %
Cholesterol 3 %
Other lipids 4 %
Carbohydrates 3 %
6. Principally cell membrane is made up of lipids and
proteins.
1. Membrane Lipids
All membrane lipids are amphipathic.
It is divided into the hydrophilic polar head and the
hydrophobic hydrocarbon tails.
The glycolipids are sugar containing lipids.
Cholesterol is more abundant towards the outside of the
plasma membrane.
7. 2. Membrane Proteins
It is studied under 2 main forms
a. Integral proteins/
transmembrane proteins
b. Peripheral proteins
i. Channel protein
ii. Carrier protein
iii.Receptor protein
iv.Pumps
8. a) Integral proteins/ transmembrane proteins
i. Channel protein
They are responsible for the transfer of small water-
soluble substance.
ii. Carrier protein
They helps to transfer materials across the bilayer through
active transport mechanism.
iii. Receptor protein
These bind with different neurotransmitters or other
chemical substances leading to the changes in
intracellular reactions.
iv. Pumps
These are also proteins and they actively transfer the ions
across the bilayer against the concentration gradient.
9. b. Peripheral Protein
They are also called as extrinsic protein.
They do not penetrate the lipid membrane completely, but
remain attached to the integral proteins.
10. They act as the receptor, some are enzyme.
It having small pores and active transport process and that
will help in the transferring of substances across the cell
membrane.
11. Nucleus
Endoplasmic Reticulum (ER)
a. Smooth endoplasmic reticulum or Agranular ER
b. Rough Endoplasmic reticulum or granular ER
Ribosomes
Golgi apparatus or Golgi bodies
Mitochondria
Lysosomes
Centrioles
Microtubules
12. Central mass within the cell called nucleus.
Protoplasm inside the nucleus called nucleoplasm
The eukaryotic nucleus is bound by double membrane, called
nuclear membrane
And this nuclear membrane externally continuous with the
endoplasmic membrane.
Nuclear membrane contain pores.
13.
14. Nucleus contain nucleoli (Singular is nucleolus)
Nucleolus is cluster of DNA
Nucleus contain 46 Chromosomes which contain genes, which
are responsible for the maintenance of the cellular structure as
well as for the control of the cellular activities.
Nuclear membrane has pores, the pores allow transfer of water
and water soluble material.
15. Layers of plasma membranes are folded inwards and forms
a vesicles are called endoplasmic reticulum.
It is largest membrane in eukaryotic cell.
It is of 2 types:-
a. Smooth endoplasmic reticulum or Agranular ER
b. Rough Endoplasmic reticulum or granular ER
16. a. Smooth endoplasmic reticulum or Agranular ER
The amount of smooth endoplasmic reticulum, varies from
cell to cell.
Function of Smooth Endoplasmic reticulum
Synthesis of fatty acids and phospholipids
Certain enzymes present in smooth ER, modify and detoxify
many toxic chemicals and carcinogens.
17. b. Rough Endoplasmic reticulum or granular ER
Those endoplasmic reticulum carries granules and that
granules are called as Ribosome.
And hence that ER called as Rough ER because
appearance is granular and rough.
Function of Rough Endoplasmic reticulum
Because of presence of ribosome, rough ER is responsible
for synthesis of certain proteins.
Also responsible for production of antibodies.
18. Ribosomes are small granules which are made up of ribosomal
RNA (rRNA) and many ribosomal proteins.
They are made up of 2 subunits; the smaller one and the larger
one both containing RNA of smaller and larger size
respectively.
Ribosomes are of 2 types
One attached to endoplasmic reticulum
Others observes free in cytosol, called cytoplasmic or free
ribosomes.
19. Synthesis of protein
Free ribosomes produces proteins to be utilized by
the cell itself.
20. Tightly packed system of smooth-surfaced vesicles
near the nucleus called Golgi apparatus.
It is made up of continuous series of flattened
membranous sacs.
The stack of Golgi sacs has 2 defined regions- Cis &
Trans.
The proteins from endoplasmic reticulum come to he
Golgi apparatus through transfer vesicles, and fuse
with the sacs of cis region.
These raw proteins are then carried to trans region.
21.
22. They stores proteins and is also responsible for
modifying them.
Through secretary vesicles these proteins are secreted
outside the cell when needed.
23. It is called as powerhouse of cell.
Intracellular organelles which are surrounded by double
unit membrane.
The number of mitochondria vary from cell to cell.
It can be less than hundreds, to more than several
thousand, depending on energy requirement of cell.
The mitochondria is composed of two lipo-protein
membranes.
a. The outer one is intact and covers the whole structures
b. Inner one is folded internally to form shelves.
24.
25. Many oxidative enzymes present in mitochondria.
These enzymes causes oxidation of nutrient, CO2 & water.
Releases energy which is utilized in formation of ATP
(Adenosine Triphosphate)
Hence, mitochondria are called as powerhouse of cell.
Causes Oxidation of
Energy
Mitochondria
Oxidative
Enzymes
Nutrient, CO2 &
Water
That energy is
utilized in the
formation of ATP
26. It is also intracellular structure surrounded by a
lipoprotein unit membrane.
It is filled with a large number of small granules
which are aggregates of digestive enzymes.
These digestive enzymes can digest proteins, nucleic
acid, mucopolysachharides and glycogen.
27. Each cell contains two centrioles which are small
cylindrical structures.
Two centrioles, together form the centrosome.
Situated near the nucleus.
Important role in cell division.
28. Many cells contain fine tubular structures called
microtubules which are arranged in bundles.
Provides rigid physical structures for certain parts of
cells like cilia.
They are also used for movement of cytoplasm.
