Where it is/What it looks like
Function
Plasma Membrane
Cell Wall
Nucleus
Nucleolus
Smooth/Rough Endoplasmic Reticulum
Golgi Apparatus
Lysosome
Vacuole
Cytoplasm

Cillia/Microvilli/Flagella

3. Be able to fill out the following chart!
Organelle
Where it is/What it looks like
Function
Plasma Membrane
Outside boarder of the cell, made of phospholipids
Lets things in and out of the cell
Cell Wall
Only in plant cells, outside of the cell
Gives plants structure
Nucleus
Middle of the cell
Brain of the cell, contains DNA
Nucleolus
Inside the nucleus
Makes Ribosomes
Smooth/Rough Endoplasmic Reticulum
Right outside the nucleus, smooth vs. Rough
Smooth – Makes Lipids, Rough – Makes Proteins
Golgi Apparatus
Flat sacks outside of the ER
Packages, and makes proteins functional
Lysosome
Used for destroying cell structures when they are old
Destroys old cell parts
Vacuole
Holds water and nutrients
Cytoplasm
The liquid part of the cell including organelles
Site for chemical reactions
Chloroplast
Only in plant cells, photosynthesis happens here.
Site of Photosynthesis
Centriole
Used in mitosis, two cylinders
Helps during cell division
Mitochondria
Found all over the cell, oval with a squiggly line.
Site of Cellular Respiration - Energy
Cytoskeleton
All over the cell
Gives the cell structure, helps in moving cells parts around.
Cillia/Microvilli/Flagella
Outside of the cell, helps to move the cell or things next to the cell.
Helps move the cell or interact with the environment.

4. The cell would be less able to break down molecules that come from the cytoplasm.
The cell would produce more proteins than it needs
The cell would have chloroplasts that appear yellow instead of green.
The cell would be less able to regulate the amount of fluid in its cytoplasm.
If a cell’s lysosomes were damaged, which of the following would most likely occur?

5. The cell would be less able to break down molecules that come from the cytoplasm.
answer

6. DNA

Mitochondria
Lysosomes
A cell from heart muscle would probably have an unusually high number of:

7. Mitochondria
Answer

8. DNA can be found in two states what are the?

9. Answer Chromatin – like spaghetti on a plate
Chromosomes – look like X’s
Answer

10. Use the picture of a cell membrane for the next question.

11. What is the molecule labeled B in the picture?
Polar phosphate molecules
Hydrophilic fatty acid tails
Non-polar phosphate molecules
Hydrophobic fatty acid tails
What is the molecule labeled B in the picture?

12. Hydrophobic fatty acid tails
Part of the phospholipid bilayer
Answer

13. t/f: The cell membrane is a phospholipid bi-layer with polar phosphate heads on the outside and non-polar fatty acids on the inside.

14. True
