Question: 168. In bryophytes, the gemmae help in which one of the following?
(1) Sexual reproduction
(2) Asexual reproduction
(3) Nutrient absorption
(4) Gaseous exchange
Answer: Option (2)
Explanation:
Gemmae are small, multicellular, green structures produced in some bryophytes such as Marchantia.
They are formed inside cup-like structures called gemma cups on the thallus.
Gemmae detach from the parent plant and germinate directly into new individuals.
This process does not involve the formation or fusion of gametes.
Therefore, gemmae are involved in asexual reproduction.
Hence, the correct answer is Option (2).
