CELL ORGANELLE STRUCTURE AND FUNCTION: You have taken the quiz on the structures and functions of organelles
and hopefully have passed! You will now need to know those so you can answer application questions about the cells.
Here are some sample questions.
4. What organelle(s) would be plentiful in a cell that makes large amounts of protein? Why?
5. What do you think would happen if digestive enzymes in a cell were NOT contained in lysosomes but floated freely
around in the cytoplasm?
6. Some cells (muscle and sperm cells) have large numbers of mitochondria. Other cells have few mitochondria. Why
is there a difference? (HINT: think about the function of the mitochondria).
Prokaryotic vs. Eukaryotic Cells
Cell wall
Cell membrane
You should also be familiar with the structure and function of the above structures found in prokaryotic & eukaryotic
cells. Be able to pick out the different cells based on a picture. Know the kingdoms that belong in each category of cell
too.
Structure & Function Lab- review the structure and function difference of the 6 cells we labeled in the lab. Be familiar
with the structures of those cells and why they have those structures (their function). Be able to identify the cells,
kingdoms, functions, and their structures.
