Looking inside cells notes (1)
This document summarizes the structures and functions of organelles found within cells. It explains that organelles such as the cell membrane, cell wall, mitochondria, vacuoles, lysosomes, chloroplasts, endoplasmic reticulum, ribosomes, Golgi bodies, and nucleus carry out specific functions to keep the cell alive. While plant and animal cells contain these organelles, bacterial cells are smaller and lack a nucleus.
Cell Similarities
All cells share several key components: a cell membrane that acts as a barrier between the interior and exterior of the cell and controls what passes in and out, hereditary material in the form of DNA that is copied when cells divide and directs the cell's activities, cytoplasm and organelles that contain the structures and chemicals that allow the cell to function, and they are generally too small to be seen without a microscope.
Life Science
The document discusses the history and development of microscopy and the cell theory. It explains that Robert Hooke first observed cells in 1663 using a compound microscope. Anton van Leeuwenhoek later observed single-celled organisms using a simple microscope. Their findings led to the cell theory, which states that all living things are made of cells, cells are the basic units of structure and function, and new cells are produced from existing cells. The document also describes how light microscopes work using lenses to magnify objects and resolve fine detail, and how electron microscopes provide even higher resolution.

All living things are made of cells, which are the basic building blocks of life. Animal cells contain a nucleus that controls cell activities, cytoplasm in the center where reactions occur, and a cell membrane that regulates what enters and exits. Plant cells have these parts as well as a cell wall, vacuoles that store water, and chloroplasts for photosynthesis. While animal and plant cells share some components, plant cells differ in having a cell wall, vacuoles, and chloroplasts.
Animal Cell comparison book
The document compares different organelles in animal cells to things in countries. It describes mitochondria as the cell's power plant, the cell membrane as security, cytoplasm as the people, the nucleus as the president, centrioles as factories, the endoplasmic reticulum as airplanes, chromosomes as a family business, the nuclear membrane as gates, the nucleolus as the government, ribosomes as a cement factory, the vacuole as jail, the Golgi body as the mail system, and the lysosome as the internet. Each comparison explains how the organelle and country thing are analogous in the functions they serve.

Plant cell wall.pptx
The cell wall surrounds plant, bacteria, fungi, algae and some archea cells but not animal and protozoa cells. It provides structural support and protection. The cell wall has three layers - the middle lamella, primary cell wall and sometimes a secondary cell wall. The primary cell wall contains cellulose, hemicellulose, pectin and cutin/wax. Secondary cell walls contain lignin. Cell walls are formed from the cell plate during cell division and provide shape and structure to cells while allowing for communication through pits. The main functions of the cell wall are mechanical strength, security, storage, communication and protection.
