“Inside Cells” Notes 10-3-2013

Organelles Tiny structures inside cell Have specific functions

1. Cell Wall Rigid Surrounds plant cells NOT in animal cells Protects & supports

2. Cell Membrane Controls what goes in & out Both animal & plant cells

3. Nucleus Cell’s control center Chromatin or chromosomes – contain genetic material “Brain” of the cell

4. Mitochondria Convert energy in food molecules to energy the cell can use to carry out its functions “Powerhouse” of the cell

5. Endoplasmic Reticulum (ER) Carry proteins and other material from one part of cell to another Maze of passageways

6. Ribosomes Make proteins Small!

7. Golgi Bodies Package materials and distribute them to other parts of the cell “mail room” of the cell

8. Chloroplasts Capture sun’s energy & use it to make food for cell

9. Vacuoles Storage areas Large in plants, small in animals

10. Lysosomes Break down materials “clean-up crew”
