Relative sizes of egg cell, morula, blastula and gustrula cells are

Relative sizes of egg cell, morula, blastula and gastrula cells are (a) Egg cell is the smallest and gastrula cell is the largest (b) All are of equal size (c) Egg cell is the largest and morula cell is the smallest (d) Egg cell is the largest and gastrula cell is the smaller.

What is the correct observation regarding size of egg, blastula and gastrula? (a) There is progressive increase in size from zygote to blastula to gastrula (b) All the three are of same size (c) Zygote is small while blastula and gastrula are larger (d) Gastrula is larger while zygote and blastula are of same size

Find out the correct sequence from below. a. Fertilisation to zygote to blastula to morula to cleavage to gastrula b. Cleavage to zygote to fertilisation to morula to blastula to gastrula c. Fertilisation to cleavage to morula zygote to blastula to gastrula d. Fertilisation to zygote to cleavage to morula to blastula to gastrula e.Zygote to fertilisation to gastrula to cleavage to morula.

Differentiate between morula and blastula.

The function of egg cell is/are

Mention the number of cells in morula and that of blastula.

The teacher said that egg cells are lager than sperm cells. What is the reason for this ?
