Cells are the basic unit of all living things and were first observed in the 17th century with the invention of the microscope. Key figures in early cell study include Anton van Leeuwenhoek who developed the first microscope, Robert Hooke who coined the term "cell", and Robert Brown who discovered the nucleus. The cell theory was developed from the work of Schleiden, Schwann, and Virchow and states that 1) the cell is the basic unit of life, 2) all living things are made of cells, and 3) all new cells come from existing cells.
This is about the history of cells. Furthermore, this includes the people behind the discovery of cells. Enjoy and have fun. This is made for the fourth grader class of Bethel International School, Pawing, Palo, Leyte, Philippines.
Godbless.

This is the report I made I uploaded it because i thought
it could be of help to those people who are looking for a simpler Fun Power Point...
it's coverages are
The cell history
the cell theory
Prokaryotic vs Eukaryotic
it doesnt have the cell structure
because my classmate
didnt gave me his report
and this is like introduction of the cell
:)
This presentation you will get how the cell theory developed.
Robert Hooke observed cells in cork and coined the term "cells”.
Anton Van Leeuwenhoek observed first living cells under the simple microscope.
Matthias Schleiden (1838) German lawyer turned botanist, concluded that, despite differences in the structure of various tissues, plants were made of cells and that the plant embryo arose from a single cell.
In 1839, Theodor Schwann, a German zoologist and colleague of Schleiden’s, published a comprehensive report on the cellular basis of animal life. Schwann concluded that the cells of plants and animals are similar structures.
By 1855, Rudolf Virchow, a German pathologist concluded that
“Omnis cellula e cellula”- new cells are formed only from pre-existing cells.
All organisms are composed of one or more cells.
2) The cell is the structural unit of life.
3) Cells can arise only by division from a pre-existing cell
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.

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”.
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.

He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

3. Cells
the basic unit of all living things.
the building blocks of all life.
The smallest unit that can still
carry on all life processes
Both unicelluar and multicellular
organisms are composed of
cells.
4. History of Cell Study
Scientists did not know about cells
until the invention of the
microscope in the 17th century
Most cells are so small they can
not be seen w/o a microscope.
5. Anton van Leeuwenhoek- Dutch naturalist
(1600’s). Developed the first microscope.
Robert Hooke- English (1665) was the first to
develop a compound microscope. He
came up with the term cell after looking at
a piece of cork
History
Robert Brown- (1831) discovered the nucleus of
the cell.
6. History cont…..
Matthias Schleiden- (German, around 1830’s) a
Botanist, concluded that all plants were made
up of cells.
Theodor Schwann- (German, worked during the
same time as Schleiden), studied animal cells.
Concluded that animals were made up of
cells.
Rudolf Virchow- (1858) concluded that all new
cells must come from previously existing
cells.
7. The Cell Theory
1. The cell is the basic unit of all living
things.
2. All living things are made up of cells.
