1. When the volume of a cell increases, what happens to its surface area?
2. Cells that can change their shapes are suited to what functions?
3. cell: plasms membrane : :
a. nucleus: chromosome
b. nucleus: nuclear envelope
c. chromosome: DNA
d. cell: DNA
4. heavy rains: flooding : :
a. osmosis: plasmolysis
b. high solute concentrations: isotonic solution
c. active transport: ATP
d. concentration difference: osmosis
(i think it's c)
5. what can be said about channels utilizing facilitated diffusion?
6. explain how ions transport across cell membranes.
7.which processes do not expend energy? diffusion, endocytosis, active transport, sodium- potassiom pump.
8. ion channels: ions : :
a. facilitated diffusion: carrier protein
b. plasmolysis: tugor pressure
c. sodium- potassium pump: ATP
d. sodium- potassium pump: sodium ( i think its d)
9. endocytosis: exocytosis : :
a. phagocytosis: bacteria
b. secrete: exocytosis
c. cold: hot (i think its c)
d. white blood cell: bacteria
10. photosynthesis: oxygen : :
a. respiration: darkness
b. light reactions: dark reactions
c. respiration: carbon dioxide
