Explanation:
Gymnosperms:
Gymnosperms are those plants in which the ovules are not enclosed inside the ovary wall and remain exposed before and after fertilisation.
They are perennial and woody, forming either bushes or trees. Some are very large (Sequoia sempervirens) and others are very small (Zamia pygmia).
Stem may be unbranched(Cycas) or branched(Pinus). Root is taproot. Leaves may be simple or compound.
They are heterosporous, produce haploid microspore and megaspore in male and female Strobili respectively.
Male and female gametophytes do not have independent free-living existence. Pollination occurs through air and zygote develops into embryo and ovules into seeds. These seeds are naked.
Example- Pines, Cycus, Cedrus, Ginkgo, etc.
