Question

What are the two components that initially move into the pollen tube after germination?

विकल्प

• The egg cell and polar nuclei

• The tube nucleus (vegetative nucleus) and the generative cell

• The exine and the intine

• The synergid and the antipodal cells

Answer 1

After the pollen grain germinates and the pollen tube begins to form, the contents of the tube nucleus (also called the vegetative nucleus) and the generative cell move into the pollen tube. These contents are essential for pollen tube growth and subsequent fertilisation.
