Question

The group of amphibian plants is
A. Funaria, Marchantia
B. Marsilia,Horse-tail
C. Pinus, Cycas
D. Typha, Hydrilla

Answer 1

Hint: Bryophytes are called the amphibians of the plant kingdom. Their male gametes need water to reach out to the female gamete to fertilize them. They need to grow in the moist damp soil area. Flowering plants make the fertilization happen in the ovules of their female gametophyte.

Complete answer:
Amphibian plants are those plants that can live both on land and in water. Bryophytes are the amphibian plants which need water for sexual reproduction but live on the land.

Let us see which among the options belong the bryophytes and are amphibian plants.
> Option A. -Funaria, Marchantia: They are the non-flowering plants belonging to the cryptogame group of bryophytes. They have soft leaves and roots. Funaria is a moss with rhizoids like structure. It is multicellular, autotrophic and amphibious. Marchantia has gemma cups with gemmae-small packets of tissue for reproduction. It can reproduce by both sexual and asexual ways. It reproduces with the help of water in a sexual method.

> Option B. -Marsilia, Horse-tail: Marsilia is a herbaceous plant that grows on the soil surface or creeper. They are usually aquatic and amphibious. Their roots are embedded in damp soil. Horsetails are primitive plants. They belong to the phyla pteridophytes. They are high growing plants.

> Option C. -Pinus, Cycas: They belong to the gymnosperm. pinus is a monoecious plant whereas cycas is a dioecious plant. Sexual reproduction occurs within the ovaries. So they can not be amphibians.

> Option D. -Typha, Hydrilla: They are aquatic plants which can survive only in the water. So they cannot survive on the land thus, cannot be the amphibians.

So the answer is option A: Funaria, Marchantia

Note: The kingdom Plantae includes all types of plants like mosses, ferns, flowering, conifers etc. they include more than the2,50,000 species. They are all multicellular and eukaryotic. They are at the second position in the number of the species after the Arthropoda phylum with 8,00,000 species.
