<span>Similarities</span> between Gymnospermes and Angiospermes:
<span>·
</span>Having seed-Gymnospermes and Angiospermes are types of plants bear seeds. They belong
to a single class known as Spermatophyta. Spermatophyta or seed
plants are those <span>plants that produce seeds.</span>
<span>·
</span>Diferentiation- The sporophyte (diploid
multicellular stage in the life cycle of a plant) of both,<span> Gymnospermes and Angiospermes,</span> is differentiated into root, stem, and leaves.

<span>·
</span>Seed-Although both
have seeds, differences between them are huge. Gymnospermes have bare, non-encased seeds. The term
"gymnosperm" in Greek means "naked seeds".
On the other hand, seeds of Angiospermes are enclosed within an ovary,
usually in a fruit.
<span>·
</span>Pollination- In Gymnospermes, the pollination is
