Match It Monday

1. Match It Monday • Mitochondria • Nucleus • Cell Membrane • Ribosome • Cytoplasm • Controls what comes in and out of cell • Where protein synthesis occurs • Powerhouse of the cell • Holds up all the organelles • Controls all cellular activity

2. Organelles What do they look like? What is their function?

3. Cytoplasm • Gel-like substance residing within the cell membrane. • It holds up all of the organelles. • Most cellular activities occur here. • 70%-90% water.

4. Cell Membrane(aka Plasma Membrane) • Cell Membrane performs a number of critical functions for the cell. • The membrane separates and protects the cell from the outside environment. • It regulates all that enters and leaves the cell; in multicellular organisms it allows self recognition. • It is composed of a phospholipid bilayer.

5. Centrioles • Centrioles are only found in animal cells. They function in cell division. The have 9 groups of 3 arrangement of the protein fibers.

6. Lysosomes • Lysosomes are called suicide sacks. They are produced by the Golgi body. They consist of a single membrane surrounding powerful digestive enzymes. They help protect you by destroying the bacteria that your white blood cells engulf. Lysosomes act as a clean up crew for the cell.

7. Mitochondria • Mitochondrion is the powerhouse of the cell. It is the site of respiration. It has a double membrane. The inner membrane is where most aerobic respiration occurs. The inner membrane is ruffled with a very large surface area. The ruffles are called cristae.

8. Rough Endoplasmic Reticulum(Rough ER) • Rough Endoplasmic Reticulum (ER) is a series of double membranes that loop back and forth. It manufactures membranes. The rough ER has ribosomes attached to it. This gives it its texture. These ribosomes manufacture proteins for the cell

9. Smooth Endoplasmic Reticulum(Smooth ER) • Smooth ER lacks ribosomes. It acts as a pathway throughout the cytoplasm. • It also produces lipids for the cell.

10. Nucleus • Nucleus is called the headquarters of the cell. It controls all cell activity. The nuclear membrane has many pores. The DNA is wrapped up as chromosomes. • The large solid spot is the nucleolus. The nucleolus is a knot of condensed chromatin. It manufactures ribosomes. It stores the information needed for the manufacture of proteins.

11. Golgi Body • Golgi Body is responsible for packaging proteinsfor the cell. Once the proteins are produced by the rough ER, they pass into the sack like cisternae that are the main part of the Golgi body.

12. Vacuoles • Vacuoles serve as the storage sites for the cells. • They are generally filled with water. • In plants they help to maintain the pressure inside the cell. • They are very large in plant cells.

13. Cilia and Flagella • Cilia are the small hair like structures around some cells. Used for locomotion. • Flagella are the long Whip like structures around a cell. Used for locomotion.

14. CytoSkeleton • The cytoskeleton is a network of protein filaments and tubules. • It transports organelles within the cell • And connects adjacent cells.

15. Organelles/features found only in plants

16. Cell wall • The Cell wall is the outer layer of the plant cell • It is located outside the cell membrane. It provides the cell with structural support and protection. • Cell walls can be found in plants, some bacteria, fungi, algae and archea. • The cell wall is made of carbohydrates, including cellulose.

17. Chloroplasts • Chloroplasts are the site of photosynthesis. They consist of a double membrane. The stacks of disk like structures are called the grana. The membranes connecting them are the thylakoid membranes. • Only in Plant cells

18. Plastids • Plastids are major organelles found in the cells of plants and algae. They are the site of manufacture and storage of important chemical compounds used by the cell. Plastids often contain pigments used in photosynthesis , and the types of pigments present can change or determine the cell's color.
