a. It is a sac found in the ovule containing 8 nucleated 7 cells
2) What is the others name of female gametophyte?
a. Embryosac
3) Where do you find the embryyosac in the flowers
a. It is found in the ovule of ovary of a flower
4) How many cells are found in embryosac & name them
a. 7 cells are found in the embryosac 3-Antipodals, 2 synergids, 1 egg & one secondary
nucleus
5) What do you mean by monosporic condition
a. Monosporic condition is referred to the embryosac obtained from one megaspare
mothercell
6) How many nuclei are found in female gametophyte
a. Totally there are 8 nuclei in female gametophyte
7) Name the part of theovule that brings the nutrition for the development
a. Funicle brings the nutrition from placeuta
8) Differentiate between a gamete and a gametophyte
a. A gamete is ahaploid fertile structure found in pollen tube and a female gametophyte

a. These cells degenerate
13)Name the pore through which pollen hibe enters the ovule
a. Generally the pollen hibe enters through micropyle
