Question

Find incorrect statement w.r.t. pollen grains:

• A. Generally spherical measuring about 25-50 micro meters
• B. Exineless areas in pollen wall are called germ pore
• C. The vegetative cell is bigger, has abundant food reserves and a large irregularly shaped nucleus.
• D. The generative cell has abundant cytoplasm and an irregular shaped nucleus

Answer 1

Answer: (D)

The generative cell is much smaller than the vegetative cell and floats in its cytoplasm. It has a spindle-shape with dense cytoplasm and a nucleus. The generative cell produces the male gametes, whereas the vegetative cell produces an elongated pollen tube, a gametophytic cell, for the male gametes to be delivered to the embryo sac.
