1. Organelles

2. Cell Wall Functions: -protects and supports plant cells -prevents water loss -made of cellulose Location: outer layer of plant cells Factory = exterior walls, sub floor and roof Body = not in animal cells

3. Cell Membrane Functions: -protects the cell, barrier -controls materials that go in and out of the cell Location: around the cell Factory = ceiling, floor, doors and windows Body = our skin with pores

4. Cytoskeleton Functions: -support structure of cell -prevents cell collapse -aids in movement -made of Microtubules (thin hollow) & Microfilaments (thin solid) network Location: Inside the cell Factory = interior walls, poles… Body = our bones

5. CYTOSKELETON

6. Functions: -control center -largest organelle Location: inside the cell, near the center Factory = Main boss’s office Body = our brain Nucleus

7. Nucleolus (Nucleoli) Function: -makes ribosomes Location: inside the nucleus (dark spot) Factory = CEO or boss man Body = cerebrum of the brain Nuclear Membrane Protects nucleus Lets things in/out of nucleus (pores) Location: around nucleus

8. Riobosomes Function: -makes proteins -float free or attached -smallest & most numerous Location: in cytoplasm or attached to E.R. Factory = secretary, memos, gophers Body = nerves of the nervous system

9. Endoplasmic Reticulum (E.R.) Function: -series of folded membranes -makes & transports proteins -two types: smooth & rough (w/ ribosomes) Location: attaches from cell membrane to nuclear membrane Factory = machines that make a product Body = stomach

11. Mitochondria Functions: -makes energy/powerhouse -has a double membrane -turns sugar to ATP Location: in cytoplasm Factory = electric power, generator Body = lungs & heart

12. Mitochondria

13. Functions: -smooth folded membrane packages proteins and secretes waste Location: in cytoplasm Factory = packaging part of assembly line Body = lg. & sm. intestines Golgi complex (or apparatus)

14. Golgi Apparatus

15. Chloroplasts Functions: -traps sun’s energy and makes food (photosynthesis) -full of chlorophyll Location: in plant cells Factory = vending machine Body = we don’t have

16. Lysosomes Functions: Contains digestive enzymes Destroys bacteria, old cell parts… Location: in cytoplasm Factory = inspectors, janitors Body = liver & kidneys

17. Functions: -stores food and water -has digestive enzymes -plants have a large one usually Location: in cytoplasm Factory = warehouse of goods Body = kidneys Vacuoles

18. Few Extra Cell Structures Cytoplasm Gel-like substances, holds all organelles in cell Location: in cell Centrioles -Helps the cell to divide Location: in cytoplasm
