Answers
As no image is attached, I'm gonna mention some identification features of each so that u can find the answer on ur own by following the mentioned characteristics.
a) Bryophytes- This will have no real stem, root or leaves. There will be just projections like those structures. Thallus(leaf-like) formation can be seen clearly. Rhizoids(root-like) can be observed under thallus.
b) Gymnosperms- Leaves, roots and stem present. To identify this kind of plants the seed structure must be seen, if the seed is naked(not covered by any pulp portion), the plant is a gymnosperm.
c) Pteridophytes- This will have real root(no tap root), stem or leaves but no flower or seed formation will be there.
d) Angiosperms- This can be easily identified by presence of flowers in it, and the seeds of this type of plants will not be naked, the seed will be covered by pulp or pulp like part.
