Female gametophyte of angiosperm consist of egg cell, synergids antipodal cell and central cell. Out of them egg apparatus consist
1 two synergids and one egg cell
2 three synergids cells
3 antipodal cells and egg cell
4 a nucleus and two antipodal cells
Explanation:
The egg apparatus of female gametophyte of angiosperm is three celled structures. It consists of one egg cell and two synergids on either side of egg cell. Three antipodal cells are present on chalazal side. The central cell (secondary nucleus) is binucleate and is present in centre of embryo sac (female gametophyte).

Eustele is present in :
1 algae
2 dicots
3 bryophytes
4 pteridophytes
Explanation:
Eustele is a type of dissected siphonostele in which vascular cylinder appears in a ring of collateral or bicollateral vascular bundles separated by medullary rays e.g., Dicot stem, which referes to the typical features of the group, namely that the seed has two embryonic leaves or cotyledons.

Consider the following statements associated with the germination of an angiospermous seed (1) as the seed gets hydrated and germinates, enzymatic activity is increased
1 1,2 and 3 are correct.
2 1 and 2 are correct.
3 2 and 4 are correct.
4 1 and 3 are correct.
Explanation:
The germination of an angiospermous seeds are associated with the following statements, as the seeds get hydrated and germinates, enzymatic activity is increased. The respiration rate of the germinating seed increases along with the increased enzymatic activity.

Triple fusion in angiosperm is the fusion of second sperm with
1 Antipodal cell and one synergid cell
2 Two antipodal cells
3 Two synergid cells
4 Two polar nuclei
Explanation:
In Angiosperm, fertilization involves two important events- Syngamy and triple fusion. The triple fusion is a characteristic feature in angiosperms where the sperm nucleus fuses with the secondary polar nuclei in the embryo sac. After pollination the pollen tube in formed carrying male gametes that move toward the egg cell one of them fuses with it by completing syngany.
