Lipids and solutions/ inside of the cell
1. Explain what it means to be selectively permeable
Selectively permeable means the cell membrane only let a certain molecules to move through them.
2. What happens to a cell that has been dropped into a hypotonic solution?(explain in case of animal cell and plant
cell and what makes the difference?)
In hypertonic solution the cell will get shriveled, and in animal cell it will be plasmolyzed. In an hypotonic
solution, animal cell will be lysed and might burst but a plant cell will be turgid. The reason why there is a
difference in the reaction is because plant cells have cell walls
3. Fill out the following table
Type of transport
Facilitated diffusion
Simple diffusion
Protein required?
yes
No
ATP required?
no
no
What type of molecules?
Ions, bigger molecule
Small non polar molecule
Down the concentration? yes
yes
4. What are the major differences in between prokaryotic cells and eukaryotic cells?
Active transport
yes
Yes
Ions, bigger molecule
No, up the concentration
Presence of nucleus, and organelles
5. What are the things that prokaryotic cells and eukaryotic cells have in common?
Cytoplasm, ribosome, DNA, and cell membrane
6. Matching
a. Mitochondria(ii)
i. site of protein synthesis
b. Lysosome (iii)
ii. Energy house
c. Rough ER (i)
iii. Break down dead organelles
d. Nucleus
(v)
iv. Post office of the cell. And modify protein
e. Golgi apparatus (iv)
v. house DNA
7. Which of the following is common in animal and plant cells?
a. Cell wall
b. Mitochondria
c. Chloroplast
d. vacuole
8. Explain the difference between pinocytosis, phagocytosis and receptor mediated endocytosis. Where does this
endocytosis occur? Pinocytosis is cell drinking, phagocytosis is cell eating. Receptor mediated endocytosis
requires receptors to recognize the right molecule
9. (T/F) plant cells don’t need mitochondria because it can produce energy from sunlight using photosynthesis
F- plant cells make monosaccharide from sunlight but the plant cells need to get ATP from this source.
10. (T/F) mitochondria and nucleus have double membrane
11. (T/F) The major difference between eukaryotic cells and prokaryotic cells is prokaryotic cells don’t have DNA and
eukaryotic cells do. False because prokaryotic cells still have DNA just not nucleus to house it.
12. (T/F) prokaryotic cells have mitochondria because they need energy to move using their flagellum. Prokaryotic
cells do not have organelles.
