Question

what must a pollen tube digest its way through to reach the archegonia?
o the bark
o microgametocyte
o nucellus

Explanation:

In plant reproduction, the pollen tube needs to grow through the nucellus to reach the archegonia. The bark is the outer - layer of a woody plant and not relevant here. Microgametocyte is a cell that gives rise to microgametes and not a structure the pollen tube passes through to reach archegonia.

Answer:

Nucellus
