1. Cell Ultrastructure

2. Parts of a cell Standard grade level required only 3 parts of an animal cell. Now we have to learn around 15!

3. What are the parts of a cell? Nucleus – now includes: Nuclear membrane Nuclear pores Nucleolus The nucleolus is the dark patch inside the nucleus, ribosomes are made here

4. New parts of a cell The cytoplasm was basically anything which didn’t include the nucleus or cell membrane It contains: Mitochondria Endoplasmic reticulum Vesicles Golgi apparatus

5. Nucleus Nucleolus makes ribosomes and RNA Nucleus contains chromatin (DNA) Nuclear membrane encloses the nucleus Nuclear pore allows movement into and out of the nucleus

6. Cell membrane Controls what enters and exits the cell

7. Golgi apparatus Process and package substances before release from the cell

8. Rough endoplasmic reticulum Transports proteins made by the ribosomes attached to the surface

9. Ribosomes These are found free in the cytoplasm or attached to the rough ER. They are where protein synthesis takes place

10. Smooth endoplasmic reticulum Produces steroids and lipids

11. Mitochondria Site of ATP production. ATP is the energy currency of the cell

12. Centriole They pull the chromosomes apart during cell division
