Question

1. what structures are formed during pollination? select all that apply. embryonic nucleus generative nucleus endospermic nucleus tube nucleus

During pollination, the pollen grain germinates on the stigma. The generative nucleus and tube nucleus are formed. The generative nucleus will later divide to form sperm nuclei, and the tube nucleus controls the growth of the pollen tube. The embryonic nucleus is formed after fertilization (not during pollination). The endospermic nucleus is also formed after double - fertilization (not during pollination).

Answer:

generative nucleus, tube nucleus
