Question

Egg of frog is
a. Microlecithal and homolecithal
b. Polylecithal and centrolecithal
c. Moderately telolecithal and mesolecithal
d. Heavily telolecithal and polylecithal

Answer 1

The yolk of intermediate size and eggs strongly concentrated into the one side of the hemisphere also known as the mesolecithal egg. These eggs are present in the later stage of the development and in the young hatch phase and characteristic by amphibian’s frog and lung of the fishes.

Complete answer:
There are several stages of the life cycle that help the frog to continue reproduction over and over again. The volume present in the frog is very huge in size about 1.6 million times larger than the normal egg present in the frog cell.

In the first stage frogs lay their eggs in the water and hatch into aquatic larvae called tadpoles and have highly specialized rasping mouths that are part of the planktivorous omnivorous and herbivorous. When metamorphosed into the adults that time, the life cycle of the frog completes and has a carnivorous diet that consists of small invertebrates. Microbiomes are highly present in the frog skin and play a vital role in the frog’s health. In their breeding season frog’s produce a wide range of vocalizations and exhibit complex behaviors to attract mates. Chytridiomycosis fungal disease spread around the world arising because of the number malformations among the frogs.

Hence, the correct answer is option (C).

Note: The moderate amount of yolk present in the mesolecithal egg. The yolk is concentrated in the upper part of the cytoplasm and lower part of the egg. The eggs present in the mesolecithal part of the frog are moderately telolecithal. Frog eggs are telolecithal and occur holoblastic cleavages and give the unequal results after the second cleavage.
