Both chorion and endometrium form the placenta, which is the embryo’s principal organ of respiration, nutrition, and excretion.Chorion is covered with ectoderm, lined with mesoderm and is separated from other embryonic membranes by the coelom. Chorion develops a rich supply of blood vessels and forms an intimate association with the endometrium (lining) of the mother’s uterus.

Conversion of spermatids to spermatozoa involves cell division.<br> a. True<br> b. False
FrozenT [24]

Answer:

The correct answer will be option-False.

Explanation:

Spermatogenesis or formation of sperm cells in humans takes place in two stages: cellular division called "spermatocytogenesis" and metamorphic changes in spermatids to spermatozoa called "Spermiogenesis".

The mitotic and meiotic cellular division produces round spermatids which undergo much physical change during the process called Spermiogenesis.  During Spermiogenesis spermatids modify themselves for fertilization like acrosome cap formation, tail development and nuclear condensation.

Thus, option-false is the correct answer.
