A. Provides structural support to the anther

Answer

B. Conducts water and nutrients to the anther

Answer

D. Positions the anther at an optimal height for pollination

Question 8

In the double fertilization process of angiosperms, one sperm nucleus fuses with the egg nucleus. What is the ploidy level of the resulting zygote?
