1 Answer
A diagram of a Marchantia thallus, as per NCERT, typically shows:
1. Dorsiventral, flattened green thallus
2. Rhizoids on the ventral surface
3. Gemma cups on the dorsal surface
4. Midrib running along the center
5. Air pores on the upper surface
6. Air chambers beneath the upper epidermis
7. Male (antheridial) and female (archegonial) branches in dioecious species
These features illustrate the unique structure of this non-vascular plant.
