FC: Cells Project By: Landon Renner and Antonio Aguilar

1: Cells Theory 1.) All organisms are composed of one or more cells. 2.) The cell is the basic unit of life in all things 3.) All cells come from existing cells

3: Robert Hooke In1655 Robert Hooke looked at sliver of cork through a microscopic lens, and discovered "pores " or "cells".He thought that the cells only excited in plants.

5: Theador Schwann Theador Schwann recognized that cells are are the basic unit of an animal structure,just as Mathis Jacob Schliden was advancing his theory of cells about animals. He formulated the basic principals of embryology by observing that the egg is a single cell that eventually develops a complete organism.

7: Rudolf Virchow He stated that the multiplication of cells formed tissues. He also stated that, "every cell stem forms another cell".

9: Matthias Jakob Schliden He was the co-founder of the cell theory (with Theodor Schwann). He discovered that both plant and animal cells have a nucleus. The nucleus acts as the brain of the cell. It helps control eating,movement, and reproduction.

10: Prokaryotic vs Eukaryotic Prokaryotic dose not have a nucleus, and Eukaryotic does.

11: Plant vs Animal Cells There are two differences between a plant and animal cell. Plant cells have a cell wall. A cell wall gives plants more of a define shape, whereas animal cells do not. Also plant cells have chloroplast. Chloroplast contains chlorophyll which provides plants with the green color to it. Other than those to parts of the cell, the rest of the structures are the same.

13: Nucleus it is enclosed in a double mambrane and communicates with the surroundings cytosol via numerous nuclear pores. Within the nucleus is the DNA responsible for providing the cell with it's unique characteristics.

15: Cytoplasm This is a collective term for the cytosol plus the organelles suspended within the cytosol.

17: Lysosome lysosomes contain hydrolytic enzymes necessary for intracellular digestion. They are common on animal cells, but rare in plant cells. Hydrolytic enzymes of plant cells are more often found in the vacuole.

19: Centrosome Is an area in the cell where plant and animal cell centrosomes play similar roles in cell division.

21: Ribosomes Are packets of RNA and protein that play a crucial role in both prokaryotic and eukaryotic cells.

23: vacuole A vacuole is a membrane-bound sac that plays roles in the intracellular digestion and the release of cellular waste products.IN animal cells vacuoles are usually small.

25: Cytoskeleton Helps to maintain cell shape.But the primary importance of the cytoskeleton is in cell motility.The internal movement of cell organelles, as well as cell locomotion and muscle fiber contraction could not take place without the cytoskeleton.

27: Golgi The Golgi apparatus is the is a membrane bound-structure with a single membrane.It is actually a stock of membrane bound-vesicles that are important in packing macromolecules for transport elsewhere in the cell.

29: smooth endoplasmic reticulum Is a vast network of membrane-bound vesicles and tubules called the endoplasmic reticulum, or ER for short.The ER is the continuation of the outer nuclear mambrane and its varied functions suggest the complexity of the eukaryotic cell.

31: Rough endoplasmic reticulum Appears "pebbled' by electron microscopy due to the process of numerous ribosomes on it's surface.Proteins synthesized on these ribosomes collect in the endoplasmic reticulum for transport throughout the cell.

33: Homeostasis Homeostasis keeps conditions in organisms constant, even if there are changes in an organisms activity level or surroundings. Homeostasis is achieved by making sure the temperature, pH, and oxygen levels are stable for your cells to survive. If homeostasis gets out of balance then you could catch diseases or illnesses.
