Q. Female gametophyte is also called as

1. embryo sac
2. ovary
3. microspore mother cell
   
4. endosperm

Q.

What is the correct sequence of the formation of female gametophyte in angiosperms?

1. Nucellus, megaspore tetrad, megaspore mother cell, megaspore, female gametophyte.

2. Megaspore tetrad, nucellus, megaspore mother cell, megaspore, female gametophyte.

3. Nucellus, megaspore mother cell, megaspore tetrad, megaspore, female gametophyte.

4. Megaspore mother cell, megaspore tetrad, megaspore, nucellus, female gametohyte.

Q. Which of the following statements is/are true?
A. Endothecium lies below the epidermal layer
B. Fusion of egg with male gamete is called apogamy.
C. Synergids are haploid.
D. The point at which funicle touches the ovule is raphe.

1. A and D only
2. A and B only
3. A and D only
4. A and C only

Q. Endosperm surrounds the zygote so endosperm should get nutrition from endosperm so why does haustaurium cells of zygote take nutrition from nucellus?
