Student Study Guide
Mr. petronio – 7th grade science - violet team

2. Is the Cell the smallest form of living things?

3. HOMEWORK REVIEW: Notice the cell parts

4. Organelles and cell parts to be familiar with…
Cell Membrane
Cell Wall
Nucleus
Mitochondria
Chloroplasts
Vacuoles
Cytoplasm
Additionally:
Be familiar with the diagram…

5. Plant Cell – Celery: “Do you recall??”
Some of celery stalks laying in the petry dish appeared to be shriveled up, while the celery stalks in water appear to stand tall.
What organelle (part of the cell) might be affected by this?
Do you believe the cell wall has been affected at all?

6. Unicellular (Prokaryotic) Cells:
Characteristics
Single celled organism
No organized nucleus
No organelles wrapped in a membrane
Ex: No nucleus, no mitochondria
Unicellular Example: Bacteria

7. Multicellular (Eukaryotic) Cells:
Characteristics
Multi-celled organism
Organized nucleus
Structured (membrane) organelles
:Life_timeline
Two types
Plant cell vs Animal cell
Examples: Skin cell, Leaf cell

8. "Karyote"Family Tree Which organism do you believe evolved first?
Will not be tested on this. Informational only…

9. What is happening here? “Do you recall?” Egg-nastic II!
1. We established the outside of an egg is covered by a protective covering of Calcium carbonate. This acts in place of what cell part not found in an actual egg?
2. What appears to have occurred in the egg labeled A? Labeled B?
3. How can we use the word "semi – permeable" to describe the two eggs?

10. Pre-Lab Review Questions: Homework questions due Wednesday 9/28/16.
1. What is the function of chloroplasts?
2. Name two structures found in plant cells but not animal cells.
3. Name three structures found in plant cells AND in animal cells.
4. What structure surrounds the cell membrane (in plants) and gives the cell support.

11. Additional practice beyond this slide…
