(i) They are specialised structures by which asexual reproduction take place in liverworts.

(ii) They are green, multicellular and asexual buds.

(iii) They develop in small receptacles called gemma cups.

• A. (i) and (ii)
• B. (ii) and (iii)
• C. (i), (ii) and (iii)

Answer 1

The correct option is D (i), (ii), (iii) and (iv)

Gemmae are a means of asexual reproduction found in many bryophytes for e.g. liverworts. They can be one to many celled, green, multicellular structures. These asexual buds develop in small receptacles called gemma cups located on the thalli. Gemmae detach from the parent body and germinate to form new individual gametophytes.
