1. Cell Review

2. Organelles!

3. Prokaryote vs. Eukaryote Prokaryote – simple, can’t carry out complex functions – Have DNA/RNA, ribosomes, cytoplasm, cell membrane – Bacteria and some other single celled organisms Eukaryotes – Have organelles-especially a nucleus – Very complex! – Includes plant and animal cells

4. Cell Differentiation Different types of cells make up our body

5. Cytoplasm The goo between the organelles

6. Nucleus Contains DNA DNA controls cellular function by containing the code for the proteins Nucleolus inside nucleus makes ribosomes Surrounded by nuclear envelope

7. Ribosomes Use code from DNA to produce proteins Contained either on Rough ER or floating in cell

8. Rough Endoplasmic Reticulum AKA Rough ER Transports newly synthesized proteins and other materials around the cell Studded with ribosomes

9. Vesicles Membrane bound sacs Float around the cell carrying different materials from place to place Has the ability to bind with cell membrane to allow things in and out of the cell

10. Mitochondria Uses glucose to produce a useable energy for the cell known as ATP This process is known as cellular respiration

11. Golgi Apparatus This organelle stores proteins until they are needed While the proteins are there, they may be modified before being packaged and shipped to their final destination (in a non-scary way)

12. Vacuoles Contain water, nutrients, waste, and ions for cellular use

13. Lysosomes Contain digestive enzymes Break down unnecessary/unused parts of the cell

14. PLANT CELLS Plant cells contain the features of the animal cell (minus the cilia and flagella) In addition they have: chloroplast, large central vacuole, and cell wall

15. Chloroplast Carries out photosynthesis Contains the pigment chlorophyll which absorbs the suns light

16. Cell Wall Plants have both! – Cell membrane controls what moves in and out of the cell – Cell wall gives the plant cell rigidity and a strong structure
