3: Robert Hooke was the first person to discover cells in 1665. | The cell is the basic unit of structure and organization of all living organisms.

4: Cell Membrane | Looks like a plastic baggie with holes in it. | Found in prokaryotic cells and animal cells | Allows certain ions and proteins to enter the cell | The cell membrane interacts with cytoplasm. The cell membrane surrounds the cytoplasm

5: Cytoplasm | Gel-like substance that holds the cells organelles together | Found inside of cells, piecing them together | Acts like a medium for transport through the cell and offers support for the cell. | Cytoplams is like glue, it holds everything together in the cell

6: Cell wall | only found in plant cells | helps form the structure of the cell. | works with the cell membrane to control the molecules going in and out of the cell | human skin is related to the cell wall because they are both used for the absorption of nutrients.

7: connects every part of the cell. | Cytoskeleton | connects ever part of the cell membrane so therefore it interacts and works with the cell membrane. | located all throughout the cell. | similar to a system of conveyor belts. | looks like straws that are all bunched together.

8: Nucleus | Membrane-enclosed organelle | Found in eukaryotic cells | Like a brain, it's in charge of everything inside of a cell | It controls all actions of the cell | Prokaryotic cells are known to not have nuclei

9: Nucleolus | Non-membrane bound structure composed of proteins and nucleic acids found within the nucleus. | Looks like a nucelous inside of another nucelous | Found in Eukaryotic cells, in the center | It's like a copy machine, replicating RNA throughout the nucleous

10: Ribosomes | A component of cells that assembles the twenty specific amino acid molecules | Looks like tiny grains on sand inside the cell | Found in the cytoplasm of both prokaryotic and eukaryotic cells | Ribsomones work well with rough endoplasmic reticulum | Like factories that produce the things you need

11: Food (sugar) is combined with oxygen to produce ATP - the primary energy source for the cell | Mitochondria | part of the cytoskeleton and powers the center of the cell | it is size of bacteria but may have different shapes depending on the cell type. | similar to a power plant in a city, because the mitochondria supplys the energy for the cell.

12: Golgi apparatus | works with the Endoplasmic Reticulum which sends proteins to the Golgi apparatus, which then modifies and packs the proteins and lipids. | looks like a stack of pancakes. | made of a series of five to eight cup-shaped, membrane-covered sacs | found in both plant and animal cells, near the Endoplasmic Reticulum.

13: Endoplasmic Reticulum (Rough & Smooth) | Found in Eukaryotic cells | The organelle called 'endoplasmic reticulum' occurs in both plants and animals and is a very important manufacturing site for lipids (fats) and many proteins | Works closely with the gogli apparatus | Rough looks like a bumpy sheet, and smooth looks like tubes

14: Vacuoles | membrane sacs that get rid of cellular waste products | found in both plant and animal cells. | in animal cells the vacuoles store water and food for the cell. | located near lysosomes. | interacts with vacuoles that fuse together to deposit waste products. | similar to a school book bag.

15: Lysosomes | interacts with vacuoles that fuse together to deposit waste products. | acts as the digestive system for a cell. | located near the vacuoles. | has a membrane around it. | lysosomes look like little membrane bubbles. | are similar to the human stomach because it breaks down food.

16: Centrioles | Ring of nine groups of fused microtubules, three microtubules in each group. It is part of the cytoskeleton. | found in animal cells only. | interacts with the cytoskeleton because the groups of microtubles are part of the cytoskeleton. | similar to police in a city they keep everything in order.

17: Cilia/Flagella | Structures that help move fluids across cell tissues | Found in animal cells | Is sometimes associated with the centriole | Considered to be like taxi, to move people place to place

18: located in plant cells. | Chloroplast | Organelles found in plant cells and other eukaryotic organisms that conduct photosynthesis | Makes food for the cell | It is like a solar panel. It takes the light and converts it to usable energy | Chloroplasts works with the whole cell

19: The End.
