1. Organelles Little organs of the cell

2. Endoplasmic Reticulum E.R. is a complex system of membranes. These membranes help to transport materials around in the cell. Acts like a highway system.

4. Smooth Endoplasmic Reticulum Membranes do NOT have ribosomes attached to them. Smooth E.R. membranes are where * synthesis of lipids * steroids are produced (gland cells) * toxic substances (alcohol) are broken down (liver cells)

6. Rough Endoplasmic Reticulum Ribosomes attached to the membranes give a “rough” appearance Proteins are produced on the ribosomes and then transferred through the rough e.r. membranes

9. Golgi Apparatus Series of membranes that aid in –1. processing –2. modifying –3. packaging and secreting (exporting proteins)

13. Lysosomes Small spherical (round) organelles that store strong hydrolytic (acidic) enzymes. Lysosomes are common in animals, protists and fungal cells. Enzymes can digest (breakdown): a. Bacteria, viruses, sugars, proteins, and old worn out cell parts.

15. Vacuoles: Plants Plants: Large central vacuole Takes up the majority of the space in the plant cell. –Stores large quantities of water –Stores metabolic waste products –Stores enzymes

16. Nucleolus Spherical area inside the nucleus where ribosomes are produced

17. Flagella Structure on cell that helps in movement Whip-like structure
