Which type of liverworts form umbrella-shaped structures that raise gametangia above the main gametophyte body and sporophytes develop below these structures?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Marchantia.
- Marchantia liverworts exhibit umbrella-shaped structures that elevate gametangia above the main gametophyte body, facilitating reproduction and fertilization. Sporophytes develop below these structures, remaining dependent on the gametophyte for nutrients.
- This reproductive strategy ensures successful fertilization and dispersal of spores, contributing to the survival and propagation of Marchantia liverworts in diverse habitats.
