Question :(i) Name and explain the two modes of asexual reproduction oberved in hydra.
(ii) What is vegetative propagation? List two advantages of using this technique.
The correct answer is -(i) The two modes of asexual reproduction observed in Hydra are:
-
Budding: In this mode, a small outgrowth or bud develops on the body of the parent organism, which grows and develops into a new individual. The bud may remain attached to the parent or detach and form a separate individual.
-
Regeneration: In this mode, a new individual develops from a small piece of the parent organism. When the parent is cut or injured, it can regenerate its lost parts, which develop into new individuals.
(ii) Vegetative propagation is a type of asexual reproduction in plants, where a new individual is produced from a vegetative part of the parent plant, such as stem, roots, or leaves. Two advantages of using this technique are:
-
Maintenance of desirable traits: When a plant with desirable traits is propagated vegetatively, the new plants will also have the same desirable traits. This allows the growers to maintain the desirable traits in the propagated plants.
-
Rapid multiplication: Vegetative propagation is a quick and efficient method of producing large numbers of plants from a single parent plant. This is especially useful in horticulture and agriculture, where large numbers of plants with similar characteristics are needed.
