Which plant tissue would not be affected by treatment with a chemical that disrupts chromosome pairing for crossing over?

Question

Quizplus · Accepted Answer

Antheridium is the male reproductive structure in hornworts which produce sperm. As sperm cells are produced by mitosis and not meiosis, they do not undergo crossing over. Thus, treatment with a chemical that disrupts chromosome pairing for crossing over would not affect the antheridium of hornworts.
