Question

A fertilized egg can be recognized by the presence of a white patch floating on top of the egg (see picture below). This white patch is called the 1. ["blastocoel", "blastodisc", "blastomere", "blastoderm"]         . It results from the 2. ["holoblastic", "meroblastic", "deuterostomic", "protostomic"]         cleavage of an aggregation of cytoplasm, called the 3. ["blastomere", "blastocoel", "blastoderm", "blastodisc"]         . During cleavage, the yolk will also divide 4. ["True", "False"]         .

Explanation / Answer

1. Blastodisc

the embryo-forming portion of an egg with discoidal cleavage usually appearing as a small white patch floating on the top of the egg.

2 meroblastic.

Incomplete cleavage due to the presence of Yolk mass

3. Blastomere

cells produced after cleavage is known as blastomere.

4 . false

cleavage is superficial. Yolk will not devide.
