Which of the statements is correct about Marchantia ?
1 Plant body is a thallus-like structure, closely attached to substrate
2 The leafy members have tiny leaf-like appendages in one row
3 Gemmae are sexual buds.
4 2 and 3 both.
Explanation:
The plant body of a liverwort is thalloid, e.g., Marchantia . The thallus is dorsiventral and closely appressed to the substrate. The leafy members have tiny leaf-like appendages in two rows on the stem-like structures. Asexual reproduction in liverworts takes place by fragmentation of thalli, or by the formation of specialised structures called gemmae.

Which of the following statement(s) is/are Incorrect about gemmae?
1 These are specialised structures by which sexual reproduction take place in liverworts.
2 They are green, multicellular and asexual buds.
3 They develop in small receptacles called gemma cups.
4 They detach from parent body and germinate to form new individuals.
Explanation:
Gemmae are a means of asexual reproduction found in many bryophytes (e.g, liverworts). They are 1 to many celled, specially produced clonal plant fragments. They are green, multicellular, asexual buds which develop in small receptacles (called gemma cups) located on the thalli. Gemmae become detached from the parent body and germinate to form new individuals.

Marchantia is
1 Monoecious
2 Dioecious
3 Both monoecious and dioecious
4 None of them
Explanation:
During sexual reproduction, male and female sex organs are produced either on the same or on different thalli. In Marchantia, archegoniophore and antheridiophore are on two different thalli. Hence, dioecious.
