Question

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

Explanation:

During pollination in plants, the pollen grain germinates on the stigma and forms a pollen - tube. Inside the pollen grain, the generative nucleus and tube nucleus are important components. The generative nucleus divides to form sperm cells, and the tube nucleus guides the growth of the pollen - tube. The endospermic nucleus is formed during double - fertilization (after pollination), and the embryonic nucleus is also a result of fertilization events post - pollination.

Answer:

generative nucleus, tube nucleus
