Which of the following statements are true of the cell wall?

i. composed of proteins and lipids
ii. composed of proteins and cellulose
iii. located in animal cells
iv. located in plant cells
v. semipermeable
vi. not permeable at all

a. ii, iii, iv, and vi only
b. ii, iv, and v only
c. i, iv, and vi only
d. i, iii, iv, and v only

The answer is B because:

Cell walls are made of cellulose and proteins (hence II).

Animal cells don't have cell walls (only cell membrane) but plant cells do so IV

They must be semipermeable since materials for example carbon dioxide and water for photosynthesis have to go into the cell some way.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

you can have just about every answer you can think of
