Question

Which of the following is a correct statement?
A. Origin of seed habit can be traced in pteridophytes
B. Pteridophytes gametophyte has protonema and leafy stage
C. In gymnosperms female gametophyte is free living
D. Antherdiophores and archegoniophores aaj present in pteridophytes.

Answer 1

Hint: The pteridophyte is a plant that is vascular. This plant has sports. These plants do not have seeds. That is why they are also known as vascular cryptogams. Pteridophytes reproduce by means of spores.

Complete answer:
The seed habit is the process in which heterospory is adopted. Under this retention and the germination of a single port also known as megasporangium. Is done to form a female gametophyte that is traced in pteridophytes.
Some of the features of pteridophytes are as under-
Pteridophytes have a life cycle of heterologous diplohaplontic type.
Pteridophytes are known to be the first land plants. They are known to be the first plants that have evolved in the earth.
Pteridophytes are seedless plants that have vascular crypto games.
The sex organs of this plant is multicellular.
These plants are mostly primitive. in one of its species leaves are even absent but rhizoids are present. The sporophyte is homosporous. .
Some of its species have well-defined body with adventitious plant body as well as root stem and leaves
The leaves of this plant are very unique as they look like feathers. It is represented by 400 jeans and 10500 species mature sporophyte is nutritionally known as independent of gametophyte. It includes living as well as fossil vascular plants.
Thus, from the above discussion we can conclude that the correct answer is option A.

Note: The division of pteridophytes include a group of primitive vascular plants. They are considered to be the first plants that were landed on earth. The adult plant body of pteridophytes is known as sporophyte.
