Which of the following statements is not correct regarding sexuality i...
Explanation:
In earthworms, both male and female sex organs are present in the same individual, a condition known as hermaphroditism. This means that earthworms have both male and female reproductive structures, allowing them to undergo self-fertilization.
Sexuality in Organisms:
Sexuality in organisms can be classified into various types based on the presence or absence of male and female reproductive structures and the occurrence of self-fertilization. The given statements describe different types of sexuality in organisms. Let's discuss each statement individually.
a) Monoecious condition:
When both male and female flowers are present on the same plant, it is called monoecious condition. This condition is indeed present in some plants like cucurbits (e.g., pumpkin, cucumber) and coconuts. The presence of both male and female flowers on the same plant allows for self-fertilization or cross-pollination.
b) Dioecious condition:
When both male and female flowers are present on separate plants, it is called dioecious condition. This condition is observed in some plants like papaya and date palms. In dioecious plants, individual plants have either male flowers or female flowers, and cross-pollination is required for fertilization.
c) Earthworms:
In the case of earthworms, the statement is incorrect. Earthworms are hermaphrodites, which means that they have both male and female sex organs in the same individual. These sex organs are located in different segments of their body. Earthworms can cross-fertilize with other individuals, but they can also self-fertilize by exchanging sperm with another earthworm during mating.
d) Cockroach:
The statement about cockroach is correct. Cockroaches are unisexual animals, meaning that they have separate male and female individuals. They exhibit sexual dimorphism, where males and females have different physical characteristics. Male cockroaches usually have longer wings and are smaller in size compared to females.
In summary, the correct statement among the given options is option 'c'. Earthworms are hermaphrodites, not monoecious or dioecious. They possess both male and female sex organs in the same individual and can undergo self-fertilization.
