Question

Write distinguished features of Gymnospermic plants​

Answer 1

Answer:

Plant body is differentiated into roots, stem and leaves. ... Leaves are of two types-foliage leaves and scaly leaves. They are pinnately compound as in Cycas or needle-like as in Pinus.

OR

Gymnosperms represent a primitive group of seed bearing plant (Spermotophytes) in which the seeds are naked i.e. they are not covered by the fruit wall as in Angiosperms (the word Gymnos means naked and spermos means seed). This is because in Gymnosperms the ovules are exposed and they are not covered by ovary.

Answer 2

Answer:

The word “Gymnosperm” comes from the Greek words “gymnos”(naked) and “sperma”(seed), hence known as “Naked seeds.” Gymnosperms are the seed-producing plants, but unlike angiosperms, they produce seeds without fruits. These plants develop on the surface of scales or leaves, or at the end of stalks forming a cone-like structure.

Gymnosperms belong to kingdom ‘Plantae‘ and sub-kingdom ‘Embryophyta’. The fossil evidence suggested that they originated during the Paleozoic era, about 390 million years ago.

Basically, gymnosperms are plants in which the ovules are not enclosed within the ovary wall, unlike the angiosperms. It remains exposed before and after fertilisation and before developing into a seed. The stem of gymnosperms can be branched or unbranched. The thick cuticle, needle-like leaves, and sunken stomata reduce the rate of water loss in these plants.
