Step 1: Understanding pseudocopulation.
- Pseudocopulation is a process in which a male insect is attracted to a flower that mimics the appearance or scent of a female insect.
- During its attempt to copulate, the insect facilitates pollination by transferring pollen.
Step 2: Mimicry in flowers. - This is an example of mimicry used by flowers to attract specific pollinators, ensuring effective reproduction.
List-I (Kind of Pollination) | List-II (Features) |
(A) Autogamy | (I) Pollination involving flowers of two different plants |
(B) Geitonogamy | (II) Pollination involving water |
(C) Xenogamy | (III) Pollination involving two flowers of the same plant |
(D) Hydrophily | (IV) Pollination involving the same flower |
(a) State the following:
(i) Kohlrausch law of independent migration of ions
A solution of glucose (molar mass = 180 g mol\(^{-1}\)) in water has a boiling point of 100.20°C. Calculate the freezing point of the same solution. Molal constants for water \(K_f\) and \(K_b\) are 1.86 K kg mol\(^{-1}\) and 0.512 K kg mol\(^{-1}\) respectively.
