In which of the following plants, hydrophily is a common phenomenon
1 Water hyacinth
2 Water lily
3 Hydrilla
4 Amorphophallus
Explanation:
Pollination carried out through water is called Hydrophily. - Pollination by water quit rare in flowering plant and it is limited to about 30 genera mostly monocotyledones. - Some examples of water pollinated plants are vallisneria and Hydrilla which is grown in fresh water and several marine sea grasses such as zosteria.

The additional nuclear ploidy levels found in a diploid angiosperm species in full bloom compared to its vegetative stage are
1 $1 \mathrm{~N} \& 2 \mathrm{~N}$
2 $2 \mathrm{~N} \& 3 \mathrm{~N}$
3 $3 \mathrm{~N} \& 4 \mathrm{~N}$
4 $1 \mathrm{~N} \& 3 \mathrm{~N}$
Explanation:
In diploid species ploidy level is $2 \mathrm{~N}$, while additional ploidy level are $1 \mathrm{~N}$ and $3 \mathrm{~N}$. $1 \mathrm{~N} \rightarrow$ found in gametes and $3 \mathrm{~N} \rightarrow$ found in endosperm (triploid).

3 A, C
4 B, D
Explanation:
$\bullet$ In South India, Hilly areas transform in to blue stretches by the flowering of Neelakurinji (Strobilanthes kunthiana). It flowers only once in 12 years. - In Angiosperms pollen grains are shed at 2-celled stage, contain one vegatative and one generative cell.

Select the mismatch :
1 Pinus Dioecious
2 Cycas Monoecious
3 Salvinia Heterosporous
4 Equisetum Homosporous
Explanation:
Pinus is the gymnosperm which posses both male and female reproductive parts and thus called monoecious and is generated on the same plant. - On other hand, cycas possess either male or female reproductive so, it is dioecious. Equisetum produces the same type spore (Homosporous) and Salvinia produces different types of spores (Heterosporous).
