Question

multiple choice question
pollen allows fertilization in angiosperms to take place
without free water.
without an egg cell.
in moist habitats only.
with swimming sperm.

Explanation:

In angiosperms (flowering plants), pollen grains carry the male gametes. Pollen can be transported (e.g., by wind, insects) to the female reproductive structures (pistil). This eliminates the need for free - standing water (unlike in some primitive plants like mosses and ferns where water is required for sperm to swim to the egg). Fertilization in angiosperms always requires an egg cell (so the option “without an egg cell” is wrong). Angiosperms are not restricted to moist habitats only (many angiosperms live in dry habitats, so “in moist habitats only” is wrong). Angiosperm pollen does not have swimming sperm (the sperm are non - motile within the pollen tube, so “with swimming sperm” is wrong).

Answer:

without free water.
