Which of the following is the first cell of female gametophytic generation in Angiosperms?
1 Megaspore mother cell
2 Microspore mother cell
3 Functional megaspore
4 Egg cell
Explanation:
The mother cell of megasporangium goes through meiosis and form megaspore quadruplicate out of which one megaspore is functional. Functional megaspore divides from mitotically developed into embryo sac for example the female gametophyte. In this way the function/megaspore fills in as the primary cell of the female gametophyte.

The ability of the venus flytrap to capture insects is due to
1 chemical stimulation by the prey
2 a passive process requiring no special ability on the part of the plant
3 specialized "muscle-like" cells
4 rapid turgor pressure changes
Explanation:
The ability of the venus flytrap to capture insects is due to change in rapid turgor pressure. It does not have muscle cell and chemical secreted by different insects does not affect the working of insectivorous plants.

With respect to angiosperms, identify the incorrect pair from the following
1 Antipodal-2n
2 Vegetative cell of male gametophyte $-\mathrm{n}$
3 Primary endosperm nucleus $-3 n$
4 Cell of nucellus of ovule $-2 n$
Explanation:
All of the cells in the embryo sac are haploid, with the exception of the central cell, which is initially binucleate until fusing its polar nuclei to become diploid. A main endosperm nucleus carrying $3 n$ is created upon fusing with one of the male gametophytes (n). The three cells on the chalazal end of the embryo sac are called antipodal cells. They are the haploid.

The megasporangium proper of an angiosperm ovule is represented by
1 Integument
2 Funicle
3 Nucellus
4 Micropyle
Explanation:
Nucellus is the megasporangium in an angio sperm ovule. Nucellus is the inner part of the ovule. Cells of nucellus are diploid. Sometime when the ovule is immature the nucellous contain the megaspore mother cell which divides meiotically to give rise to megaspore.
