Which of the following is pollinated by water?

Options:
A Viola
B Yucca
C Oxalis
D Zostera

The correct answer is:
Zostera

Solution:
Transfer of pollen grains from the anther of one flower to the stigma of another flower by the agency of water is called hydrophily. Hydrophily are of two types â hypohydrophily and epihydrophily.
a) Hypohydrophily: In this type, pollination occurs below the water surface. e.g., Zostera, a hypohydrophilous flower bears elongated needle-like pollen grains without exine.
b) Epihydropily: In this type, pollination occurs on the surface of water. e.g., Vallisneria.

Which of the following is reducing and non-reactive sugar?

Options:
A Galactose
B Gluconic acid
C Methygalactoside
D Sucrose

The correct answer is:
Sucrose

Solution:
A sugar without a hemiacetal is non-reducing because it does not behave as a reducing agent toward oxidizing metal salts. Sucrose is one example of a non-reducing sugar. Different tests can work out whether sugar is reducing or non-reducing, by detecting the presence of free aldehyde or ketone groups. Sucrose is less reactive and more likely to survive the journey in the phloem.
