Question

Characteristics of pteridophytes and campare it with bryophytes and gymnosperms

Answer 1

Explanation:

The plant body of bryophytes is not differentiated into true roots, leaves and stem (i.e. they are thalloid plants) while the plant body of pteridophytes are distinguished into true roots, leaves and stem. Bryophytes are non-vascular plants while pteridophytes are vascular plants (i.e. contain xylem and phloem).

Answer 2

Answer:

first of all, I would like to mention that all these categories are under plantae kingdom.

-: THALLOPHYTES :-

thallophytes are plants with non-well differentiated body. most of the plants are aquatic. examples - cladophora, Chara etc.

-: BRYOPHYTES :-

bryophyta are also known as the amphibian of plant kingdom since they need both water and land for their survival. they are differentiated to form leaf and stem structures. but don't have any specialised tissue for the conduction of water. example - moss, funaria etc.

-: PTERIDOPHYTA :-

pteridophytes are well differentiated into roots, stems and leaves. they also have specialised tissue for the conduction of water and other minerals throughout the plant body. examples - fern, marsilea etc.

now, these three types of plant don't beat fruits or seeds. bryophyta, thallophyta, pteridophyta have naked embryos called spores and the reproductive organs are hidden.

let's come to gymnosperms and angiosperms. they are seed and fruit bearing plants. they both together are called phanerogams.

-: GYMNOSPERMS :-

gymnosperms bear naked seeds and the plants are usually perennial or Woody. gymnosperms are non-flowering plants. example - pinus, cycas etc.

-: ANGIOSPERMS :-

angiosperms are flowering plants and the seeds develop inside the organ which is modified to become a fruit. examples - mango, apple tree etc.
