Frequently Asked Questions

What are the four types of gymnosperm?

There are four major types of gymnosperms. They are conifers, cycads, ginkgo, and gnetophyte.

What is difference between pteridophytes and gymnosperm?

Differences between Pteridophytes and Gymnosperms: The sporophytic plant body is by and large arborescent in gymnosperms while it is not so in pteridophytes. Roots are adventitious in pteridophytes while they arise from the radicle (tap root) in gymnosperms. ADVERTISEMENTS: Pteridophytes may be homosporous or heterospoers, while all gymnosperms are heterosporous. More items...

What is an example of a gymnosperm?

Examples of gymnosperms are fir trees, spruce trees, pine trees, cycads and ginkgo trees. Examples of angiosperms include oak trees, maples, birches, forsythias, daisies, lilies and lilac bushes. Gymnosperm means "naked seed," although the seeds of these types of plants aren't found in fruit as they are in angiosperms.

What is the meaning of gymnosperms?

Definition of gymnosperm. : any of a group of vascular plants that produce naked seeds not enclosed in an ovary, that were formerly considered a class (Gymnospermae) of seed plants, but that are now considered polyphyletic in origin and divided into several extinct divisions and four divisions with surviving members typified by the cycadophytes,...
