Question

First land inhabiting plants are ________.
A) Bryophytes
B) Angiosperms
C) Pteridophytes
D) Gymnosperms

Answer 1

The plants which inhabit themselves to survive on the land are known as land inhabiting plants. Algae are commonly found in water while the Bryophytes are known as amphibians. They depend on water for their fertilization. Water is the pollinating agent of these plants. First land inhabiting plants are nonvascular plants.

Complete answer:
Bryophytes constitute the non-vascular land plants. They can also survive in the dry environments. They produce enclosed reproductive structures such as gametangia and sporangia. The gametes are transported with the help of water for the process of fertilization. They do not produce flowers and seeds. They have un-branched sporophytes and life cycles are dominated by the gametophytes stage. They do not contain lignin. They exist in a wide variety of habitats. For ex- liverworts, hornworts and mosses, etc.
Angiosperms are plants that produce flowers. They bear their seeds in fruits. These are the largest and most diverse groups within the kingdom plantae. Fruits, trees, shrubs, grasses and flowers are angiosperms. They are of two types: monocots and dicots.
Pteridophytes are vascular plants that have free-living gametophyte and sporophyte phases that are independent at maturity. It is well differentiated into roots, stem and leaves. for ex- Ferns, horsetails and club-mosses.
Gymnosperms are the group of seed producing plants that includes conifers, cycads and gnetophytes. These are vascular plants whose seeds are enclosed by mature ovaries or fruits.
Bryophytes lie lower than pteridophytes from the point of view of evolution. These are land inhabiting plants and have adapted themselves to a terrestrial life. Bryophytes are known as the amphibians of the kingdom Plantae. The gametes move by the help of water.
From the above information we have found that First land inhabiting plants are Bryophytes.

Therefore, the correct answer is option A.

Note:
Bryophytes can grow where vascularized plants cannot because they do not depend on roots for an uptake of nutrients from the soil. They can survive on rocks and bare soil. They have life cycles with alterations of generations. Chlorophyll a and b is present in Green algae, bryophytes and vascular plants. They can also produce starch stored in the plastids and contain cellulose in their walls.
