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.

true is the

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
