This document provides an overview of key cellular structures and their functions, including:
- Eukaryotic cells contain membrane-bound organelles like the nucleus, mitochondria, and chloroplasts, while prokaryotes do not.
- The cytoplasm, including cytosol, organelles, and inclusions, is the "factory area" where most cell activities occur.
- The cytoskeleton helps give cells their shape and allows organelle movement.
- The cell nucleus contains most of the cell's genetic material and coordinates the cell's activities.
- Mitochondria produce energy in the form of ATP and play roles in metabolism, apoptosis, and hormone production.

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.

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 French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

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.

4. They contain membrane-bound organelles,
such as the nucleus, while prokaryotic cells
do not.
Differences in cellular structure:
eukaryotes include the presence of
mitochondria, chloroplasts,
cell wall and the structure
of chromosomal DNA.
Eukaryotic cells:
5. functions:
There are some types of cells are specialized
to perform specific functions for example:
nerve cells whose function is to transmit tiny
electrical pulses around an animal's nervous
system.
Although different types of cells generally
have different specialized functions, some
types of processes are common to all, or at
least most cell
7. Cytoplasm
Cytoplasm is the substance
of a cell other than that of
the nucleus.
Cytoplasm is made up of
three major elements;
cytosol, organelles, and
inclusions.
Most cellular activities
happen in the cytoplasm.
The cytoplasm can be
thought of as the “factory
area” of the cell.
8.
9. The structure of the
cytoplasm:
• contents of cells between the plasma
membrane and nucleus envelope.
It consists of a set of organelles suspended in
a liquid called essential cytosol, its consists
mostly of water containing mineral salts and
organic materials dissolved .
10. The function of the
cytoplasm:
responsible for many cellular
processes like:-
Movement of the different cellular
elements.
Convert physical and chemical stimuli
into action potentials.
Synthesis and secretion of steroids.
11. Cytoskeleton:
It is a series of intercellular protein that
help the cell with shape.
12. The structure
The main structures are:
Microfilaments: are hollow tubes made of tubulin.
Intermediate filaments
Microtubules
13. The function of cytoskeleton
Make the shape of the cell without
need to walls
Organelle movement: help move
organelles from place to place in the
cell.
14. It is the fluid in which organelles of the cell
reside. This is often confused with cytoplasm,
which is the space between the nucleus and
the plasma membrane.
Cytosol
15. The structure of cytosol :
It is composed of water, salts and organic
molecules. Cytosol is composed of a mixture of
cytoskeleton filaments, organic and inorganic
molecules that are dissolved. The inner, more
fluid and granular potion of the cytoplasm is
known as the endoplasm.
16. The function of cytosol
It has enzymes that take molecules and
break them down, so that the individual
organelles can use them as they need to.
The cytosol also contains the cytoskeleton
which gives the cell its shape and can help
in the movement of the cell.
17. Cell nucleus:
It is a membrane-enclosed organelle
found in eukaryotic cells and It contains
most of the cell's genetic material.
18. The Structure of Cell nucleus:
1- Nuclear envelope :
known as nuclear membrane, consists
of two cellular membranes, an inner and
an outer membrane, arranged parallel to
one another.
2- Nuclear pores:
which provide aqueous channels
through the envelope, are composed of
multiple proteins.
19. 3- Nuclear lamina:
two networks of intermediate filaments provide the
nucleus with mechanical support.
It is composed mostly of lamin proteins
4- Chromosomes:
The cell nucleus contains the majority of the cell's
genetic material in the form of multiple linear DNA
molecules organized into structures called
chromosomes
Each human cell contains roughly two meters of
DNA. During most of the cell cycle these are
organized in a DNA-protein complex known as
chromatin
20. 5- Nucleolus:
It is a discrete densely stained structure
found in the nucleus. It is not surrounded
by a membrane, and is sometimes called
a suborganelle
The main roles of the nucleolus are to
synthesize rRNA and assemble ribosomes
21. The function of nucleus
The nucleus is a highly specialized
organelle that serves as the information
processing and administrative center of the
cell.
It coordinates the cell's activities, which
include growth, intermediary metabolism,
protein synthesis, and reproduction
23. Structure of mitochondria:
Outer membrane
It is smooth and is composed of equal amounts
of phospholipids and proteins.
It has a large number of special proteins known
as the porins.
Inner membrane
It is folded into a number of folds many times
and is known as the cristae.
This folding help to increase the surface ares
inside the organelle.
24. Matrix
The matrix of the mitochondria is a complex
mixture of proteins and enzymes. These
enzymes are important for the synthesis of
ATP molecules, mitochondrial ribosomes,
tRNAs and mitochondrial DNA.
25. Functions of mitochondria:
The most important function of the
mitochondria is to produce energy. The
energy known as ATP molecules.
It is also help in building certain parts of
blood and hormones like testosterone and
estrogen.
play important role in the process of
apoptosis or programmed cell death.
