Question

Human egg are
A. Microlecithal
B. Alecithal
C. Macrolecithal
D. Mesolectithal

Answer 1

Hint: Human egg is very small and produces very little yolk. This type of egg has a limited amount of yolk or no yolk.

Complete answer:
The ovum, or egg, is one of the largest cells in the body of humans. It is very thin, with a diameter of about 0.12 mm. Ovaries produced eggs, which are usually found behind the belly of a woman under the kidneys. The eggs grow from small cells inside the ovaries through different stages of growth, known as oogenesis, to release during ovulation once a month. Typically, every ovary takes turns releasing eggs every month, but the remainder of the ovary continues to supply eggs for release if one is inactive or defective.
Single eggs with tiny yolk are called microlecithal, medium-sized yolk-like eggs are called mesolecithal, and large condensed yolks are known as macrolecithal. This group of eggs is based on chordate eggs, but the concept encompasses the entire animal world.
Human egg is very small and produces very little yolk, called alecithal egg. An alecithal egg has a limited amount of yolk or no yolk. Yolk provides the nutrients required for the growth of the embryo and its existence is also important for oviparous species.

Hence, the correct answer is option (B)

Note: The egg is the organic vessel which contains the zygote where an embryo grows until it can live alone. The fertilization of an egg cell results in an egg. Many vertebrates, arthropods, and mollusks lay eggs, but others such as scorpions do not.
