| I. Parthenium is a plant that causes pollen allergy. |
| II. If tapetum is destroyed, then unfeasible male gametophytes are produced. |
| III. Egg apparatus has 3 synergids and 2 antipodal cells. |
| IV. Megaspore is the first cell of gametophytic generation. |
A) I and II
B) I and III
C) Ill and IV
D) I and IV
Correct Answer: C
Solution :
Only statements I and IF are correct. As the pollens Parthenium plant can cause pollen allergy. The malfunctioning of tapetum does not nourish the developing pollen grains, thus fails to produce viable male gametopbyte. In an embryo sac, there are 2 synergids +3 antipodal cells +1 egg cell and polar nuclei. Microspore or pollen grain is the tot cell of gametophytic generation.
