Answer» Correct Answer - d The carpogonium (female sex organ) in Nemalion, one of the simplest red alga, consists of a swollen basal part containing the female nucleus and an elongated terminal hair-like structure called the trichogyne. During fertilization the spermatium (male gamete) discharges its contents into the latter. the spermatium nucleus migrates downwards to fuse with the egg nucleus in the basal swollen part of the carpogonium. soon after fertilization the trichogyne shrivels. |
