Question
Which of the following statements are correct w.r.t. liverworts?a) Commonly found on banks of streams and moist and shady places.b) Gemmae are green, multicellular, asexual buds.c) Marchantia is a thalloid, dioecious liverwort.d) Rhizoids are multicellular.
Solution
All of the statements are correct with respect to liverworts.
a) Liverworts are commonly found on the banks of streams and in moist and shady places. They prefer damp habitats because they lack the protective structures against desiccation that are found in more advanced plants.
b) Gemmae are indeed green, multicellular, asexual buds. They are produced in structures called gemma cups located on the thallus (the leaf-like part of the liverwort). When raindrops fall into the gemma cups, the gemmae are splashed out and can grow into new plants if they land in a suitable habitat.
c) Marchantia is a thalloid, dioecious liverwort. This means it has a flat, leaf-like body (thalloid) and separate male and female plants (dioecious).
d) The rhizoids in liverworts are multicellular. Rhizoids are hair-like structures that help the plant attach to the substrate and absorb water and nutrients.
