Question

Which statement best distinguishes plant cells and animal cells?
1. There are more ribosomes in animal cells than in plant cells.
2. Plant cells have more lysosomes than animal cells have.
3. Plant cells have large vacuoles, and animal cells do not.
4. The position of the nucleus in the cells is different in plants and animals.

Answer 1

Option 1: Ribosomes exist in all cells and there is no major difference between animal cells and plant cells. It depends more on the function or purpose of the cell. Recall that ribosomes are involved in protein/gene expression. There would be more ribosomes, in let's say, GABA-producing neuron as compared to a osteocloast because a GABA-producing neurons need to produce the inhibitory amino acid neurotransmitter GABA, in which ribosomes' roles are vital. Osteoclasts clean up bone tissue instead. There is less need for ribosomes.

Option 2: Plant cells don't normally have lysosomes. Animal cells do. This is wrong.

Option 3: This is correct. Plant cells have large central vacuoles, animal cells would just have contractile, normal, and a few other. No large

Option 4: Position of nucleus is arbitrary and insignificant

Answer 2

A nice thing to remember is this:

Animal cells ONLY
Lysosomes, Centrioles, Flagella
Plant cells ONLY
3'Cs, Plasmodesmeta

3'Cs are: cell wall, chloroplasts, central large vacuole

Answer 3

thank you so much
