Answer 1

Answer: (D)

• A-Exine: The outer layer of pollen grain is made up of sporopollenin.
• B - Intine: The inner pecto-cellulosic layer.
• C - Vegetative cell: It functions in the extension of a pollen tube to transport the two sperm cells to the embryo sac.
• D - Germ pore: A thin-walled area through which the germ tube or pollen tube emerges on germination.
• E - Generative cell: This cell divides to form two male gametes (sperm cells).
