a student is comparing the cells of a prokaryote, an animal, and a plant. identifying which two cell parts would show that the cell was a plant cell, and not a cell of a prokaryote or an animal?

a nucleus and mitochondria
b cell wall and cell membrane
c cell wall and chloroplast
d cell membrane and mitochondria

Explanation:

Question 19

Lysosomes have hydrolytic enzymes that break down macromolecules (lipids, carbs, proteins) for digestion/recycling. Packaging (b) is Golgi, building (c) is ribosomes/ER, storing (d) is vacuoles. So (a) is correct.

Prokaryotes lack organelles, animal cells lack cell wall/chloroplast. Plant cells have cell wall (not animal) and chloroplast (for photosynthesis, not in animal/prokaryote). Nucleus (a) is in eukaryotes, cell membrane (b/d) is in all, so (c) is correct.

Answer:

a. Lysosomes break down lipids, carbohydrates, and proteins
