1. Functions of Cell Organelles

2.  1. nucleus - controls all cell activities  2. endoplasmic reticulum - (ER)network of passageways, carries materials within cell  3. golgi body - receives materials from ER, packages and sends the materials to other parts of the cell. Also releases materials to outside of cell.

3.  4. cell membrane - forms a barrier between the cytoplasm and the environment. Controls what enters and leaves the cell.  5. vacuoles - store food, water, waste and other materials. Most plant cells have one large vacuole.  6. lysosomes - small organelles that digest food particles and worn-out cell parts.

4.  7. mitochondria – produce the cell’s energy  8. cytoplasm – gel-like fluid in which the organelles are found  9. ribosomes – produce proteins. May be attached to ER.  10. chromosomes – the instructions for all cell activities

5. Summary  Cell organelles each have…  Organelles work together to…  The chromosomes…  Some differences between plant and animal cells include…

6. Plant Cell differences.  Plant cells have a cell wall. (like our bones)  Plant cells have one large vacuole.  Plant cells have chloroplasts. (make their own food using sun)
