Read the following statements. (NEET 2021)(a) Metagenesis is observed...
- Those cnidarians which exist in both forms exhibit alternation of generation (Metagenesis), i.e., polyps produce medusae asexually and medusae form the polyps sexually (e.g., Obelia).
- The body bears eight external rows of ciliated comb plates, which help in locomotion.
- Roundworms have organ-system level of body organisation.
- They are triploblastic and coelomate animals.
- The most distinctive feature of echinoderms is the presence of water vascular system which helps in locomotion, capture and transport of food and respiration.
Most Upvoted Answer
Read the following statements. (NEET 2021)(a) Metagenesis is observed...
The correct answer is option (b) (b), (c) and (e) are correct.
Explanation:
(a) Metagenesis is observed in Helminths:
Metagenesis is the alternation of generations in the life cycle of an organism. Helminths are parasitic worms which do not exhibit metagenesis. Hence, this statement is incorrect.
(b) Echinoderms are triploblastic and coelomate animals:
Echinoderms belong to the phylum Echinodermata which includes starfish, sea urchins, and sea cucumbers. They are triploblastic animals, meaning they have three germ layers in their embryonic development. They are also coelomate animals, meaning they have a true body cavity called coelom. Hence, this statement is correct.
(c) Round worms have organ-system level of body organization:
Roundworms belong to the phylum Nematoda which includes organisms like Ascaris, hookworms, and pinworms. They have an organ-system level of body organization, meaning they have specialized organs for different functions. Hence, this statement is correct.
(d) Comb plates present in ctenophores help in digestion:
Ctenophores are a group of marine animals commonly known as comb jellies. They have eight rows of comb-like structures called ctenes which they use for movement. Comb plates are not involved in digestion in ctenophores. Hence, this statement is incorrect.
(e) Water vascular system is characteristic of Echinoderms:
Echinoderms have a unique system called the water vascular system which helps in locomotion, respiration, and feeding. This system is characterized by a network of fluid-filled canals and tube feet. Hence, this statement is correct.
Therefore, option (b) is the correct answer as statements (b), (c), and (e) are correct.
