FC: All About Cells | By:Dharini And Destiny

1: Cell Theory | 1)All living things are made up of cells and the products of those cells. | 2)Cells carry out their own life functions and are the basic unit of structure. | 3)New cells come from other living cells.

2: Scientists | In 1838,Matthias Schleiden concluded that all plants are made of cells. In 1839,Theodore Schwann concluded that all animals are made of cells. In 1855,Rudolf Virchow concluded that all cells came from pre-existing cells. In 1665 ,Robert Hooke described cells when looking at a piece of cork under a microscope He called the small spaces in the wood “cellulae”[latin for rooms] | Schleidan | Schwann | Virchow | Hooke

3: Prokaryotic Cells | Cell Membrane Cell Wall Capsule Nucleoid Cytoplasm Chromosomes[One long DNA] Cilia & Flagella[Simple] Ribosomes Plasmid Glycocalyx | [bacteria has prokaryotic cells]

4: Eukaryotic Cells | Nucleolus Nucleus Ribosomes Vesicle[bubbles of liquid inside a cell that stores and transports various substances within that cell] Rough Endoplasmic Reticulum Golgi Apparatus Cytoskeleton Smooth Endoplasmic Reticulum Mitochondria Cytoplasm Lysosome Cell Wall | People[we] have eukarotic cells

5: Nucleus Cilia Cytoplasm Endoplasmic Reticulum[smooth and rough] Ribosomes Mitochondria Centrioles Golgi Apparatus Cell Membrane Mictotubules/Microfilaments Flagella[found in some cells] | Animal cells

6: Plant Cells | Nucleus Chloroplast Cytoplasm Endoplasmic Reticulum(smooth and rough] Ribosomes Mitochondria Plastids Golgi Apparatus Cell Wall Cell Membrane Flagella[found in some cells] Onlarge vacuole

7: How It Works: | The keeping up of a constant environment in the body. | When there's too much of a substance inside the cell, the membrane excretes it to where the cell is under control/ maintained | Homeostasis: | The opposite occurs when there is not enough of the substance inside the cell.

8: How It Works: | Cell Structures | Cell Wall[provides support and protection,found in plant,fungi,bacteria cells] | Cell Membrane[Controls movement of materials in/out of out of cells, found in all cells] | Nucleus[Controls cell activities]

9: Cell Structures | Cytoplasm[Supports and protects cell organelles, found in all cells] | Vacuole[Store food, water, metabolic & toxic wastes, found in animal and plant cells] | Chloroplast[Uses energy from sun to make food (glucose) for the plant. found in plant cells and algae]

10: Cell Structure | Cilia[moves cells around, found in animal cells] | Nucleolus[Makes ribosomes, found in all cells except prokaryotes] | Centrioles[Separate chromosome pairs during mitosis, found in animal cells] | Cytoskeleton[Strengthens cell and maintains shape, found in all cells]

11: Cell Membrane | The cell membrane maintains/decides what comes in the cell and what goes out of it. | hospholidid heads, the hydrophobic tails, carbohydrates, and the carrier proteins | The hospholidid makes sure the membrane stays in place. | The hydrophobic head/tail sets the boundary on cell contents | Carbohydrates make the membrane stronger | The Protein supports the membrane.
