1. Tour of The Cell

2. Learning Targets  I can distinguish between prokaryotic and eukaryotic cells  I can draw a prokaryotic cell, a plant cell and an animal cell  I can identify the structure and function of the following  ribosomes  rough and smooth Endoplasmic reticulum  golgi apparatus  nucleus  nucleolus  vessicle  vacuoles  lysosomes  mitochondria  chloroplasts  I can identify organelles that are shared by plant and animals cells and those that are unique to plant and animal cells.  I can explain the importance of the surface area to volume ratio with regard to cell efficiency, and limitation to cell size.  I can predict and justify how a change in a cellular organelle would affect the function of the entire cell or organism.

3. Focus Questions  1. What is the difference between prokaryotic and eukaryotic cells?  2. What are the organelles involved in the endomembrane system?  3. What organelles are unique to plant and are unique to animal cells?  4. What would happen to a cell that has nonfunctioning  ribosomes  golgi apparatus  endoplasmic reticulum  vesicles  nucleolus  Lysosomes  Mitochondria
