Question

What parts on a onion cell can you not see and why?

Answer 1

chloroplast :3

Answer 2

@pengembara_bumi1 you forgot to explain the "why" part

Answer 3

Because the chloroplasts that actually photosynthesize are found in the tops of the onions - the part that is actually above ground. There's no reason for there to be chlorophyll in the onion skin itself because these grow underground
