1. Chapter 3 Test Review

2. 1. State the function of each of the following parts:
Cell Membrane – allows material to enter and leave the cell
Mitochondria – take food and releases energy for the cell
Cytoplasm – jelly-like substance in the cell membrane
Nucleus – directs all cell activity

3. 1. State the function of each of the following.
Cell wall – protects the plant cell and gives it shape
Golgi Bodies- flattened materials that package cellular substances and sent them out
Organelles – structures within the cytoplasm of eukaryotic cells
Lysosomes – contain digestive chemicals to breakdown waste
Vacuoles – membrane bound space for temporary storage in cells

4. 2. State the Cell Theory
All cells come from other cells that already exist.

5. 3. What are the differences in an animal and plant cell?
Has a cell wall
Has chloroplast
Animal Cell
Do not have cell walls
Do not have chloroplast.

6. 4. Know the organization of all living things (start with the cell).
Tissue
Organ
Organ System
Organism
Cell is the smallest unit of an organism.

7. 5. What is tissue?
A group of cells that work together to do one job.

8. 6. What is an organ system?
A group of organs working together to perform a certain job.

9. 7. What is the definition of a prokaryotic cell? Give an example.
Cells found only in one – celled organisms.
Bacteria

10. 8. The ______ is usually the largest organelle in the cell.
Nucleus

11. 9. Explain the difference between eukaryotic and prokaryotic cell.
Eukaryotic Cells
Found in many celled organisms that contain organelles.
Have a membrane bound structure.
Prokaryotic Cells
A one celled organism that does not contain organelles. Found in bacteria.
Do not have a membrane bound structure.

12. 10. What is one difference between one celled organisms and cells that make up an organ?
Single celled – perform all their life functions by themselves.
Organ cells – work together and depend in some way on other cells.
