Directions: In the following questions, a statement of assertion (A) ...
Assertion: Unisexual flowers have separate male and female flowers whereas a typical monocot embryo comprises an embryonal axis with a single cotyledon.
Reason: Cucumber, pumpkin, and watermelon are examples of unisexual flowers.
Explanation:
The given assertion states that unisexual flowers have separate male and female flowers, while a typical monocot embryo has an embryonal axis with a single cotyledon. The reason provided is that cucumber, pumpkin, and watermelon are examples of unisexual flowers.
Unisexual Flowers:
Unisexual flowers are those that have either male or female reproductive organs but not both. In these flowers, the male and female parts are present on separate flowers of the same plant. For example, in cucumber, pumpkin, and watermelon plants, the male and female flowers are present on different plants. The male flowers produce pollen, which is transferred to the female flowers for fertilization.
Monocot Embryo:
A monocot embryo refers to the embryo found in monocotyledonous plants (monocots), which are a type of flowering plants. Monocots have a single cotyledon (seed leaf) in their embryos. The cotyledon is an important part of the seed that provides nutrients to the developing plant.
Explanation of Assertion and Reason:
The assertion is true because unisexual flowers do have separate male and female flowers. This is evident in plants like cucumber, pumpkin, and watermelon, where male and female flowers are present on separate plants.
The reason is also true because cucumber, pumpkin, and watermelon are indeed examples of unisexual flowers. In these plants, the male and female flowers are present on different plants. The male flowers produce pollen, while the female flowers have the ovary where fertilization takes place.
However, the reason does not explain why a typical monocot embryo has a single cotyledon. The reason only provides an example of unisexual flowers but does not establish a connection with the structure of the monocot embryo.
Therefore, both the assertion and reason are true, but the reason is not the correct explanation of the assertion. Thus, the correct answer is option B: Both assertion (A) and reason (R) are true, but reason (R) is not the correct explanation of assertion (A).
Reason: Cucumber, pumpkin, and watermelon are examples of unisexual flowers.
Explanation:
The given assertion states that unisexual flowers have separate male and female flowers, while a typical monocot embryo has an embryonal axis with a single cotyledon. The reason provided is that cucumber, pumpkin, and watermelon are examples of unisexual flowers.

Therefore, both the assertion and reason are true, but the reason is not the correct explanation of the assertion. Thus, the correct answer is option B: Both assertion (A) and reason (R) are true, but reason (R) is not the correct explanation of assertion (A).
