Gymnosperms (meaning "naked seeds") are seed-bearing plants that don't produce flowers, instead they have male and female reproductive organs mostly in the form of cones. Their microsporophylls release pollen into the air to make available to the ovule, in the megasporophylls causing fertilization. Their seeds develop without a protective covering of ovary wall. Conifers (like pines, redwoods, and fir), gingkos, seed ferns, cycadeoids, and cycads are gymnosperms.

Hope this is helpful!

Plants that reproduce from seeds fall into two groups angiosperms and gymnosperms. They both produce seeds but the gymnosperms do not have flowers the seeds mature in cones.

1. Gymnosperms are vascular plants and mosses are non-vascular 2. Gymnosperms reproduce by seeds and mosses by spores

Plants belonging to bryophytes and Pteridophytes etc. reproduce with spores and thoseof gymnosperms and angiosperms reproduce with seeds.

The main difference between angiosperms and gymnosperms is their reproduction. Angiosperms are flowering plants and bear seeds while the gymnosperms reproduce through exposed seed.

They both are plants that reproduce, and they both have seeds.

Sequoias are gymnosperms and do not produce flowers to reproduce.

Vascular plants reproduce by using seeds. For example, gymnosperms and angiosperms. Nonvascular plants reproduce by using spores or other methods.

Gymnosperms ( naked seeds ) and angiosperms ( enclosed seeds ).

Sperm cells are located in the pollen grain, as with most plants that reproduce sexually.

Gymnosperms (conifers and other cone bearing plants) are a non-flowering plant group that do not reproduce via spore

NOConifers are gymnosperms, which literally translates to naked seeds, they have seeds. They reproduce with pollen just like flowering plants (angiosperms) and do not use spores to reproduce.

Many non-flowering plants (such as ferns) reproduce by means of spores; the other major non-flowering plant group are gymnosperms, which produce seed, but in cones not flowers

Most of the vascular plants have flowers, thus implying that they reproduce by seeds-gymnosperms. By contrast, non-vascular plants don't usually have flowers and thus reproduce by other means; for example, fungi reproduce by spores.

Most gymnosperms have reproductive structures called cones. Cones are covered with scales. Most gymnosperms produce two types of cones: male cones and female cones. Usually, a single plant produces both male and female cones. In some types of gymnosperms, however, individual trees produce either male cones or female cones. A few types of gymnosperms produce no cones at all.

Two adaptions that help seed plants reproduce on land are pollen and flowers. Other adaptions that help are shape, gymnosperms and angiosperms.

Both can reproduce by sexual means by producing seeds. The only difference between the reproduction of angiosperms and gymnosperms is that seeds in angiosperms are produced inside the fruit but in gymnosperms seeds remain nacked on the megasporophyll.

There are various types of submerged plants, they may be algae , brophytes ,pteridophytes, gymnosperms and angiosperms. Submerged plants also reproduce like terrestrial ones. There may be isogamy , anisogamy, oogamy.

It starts with a seed or spores and slowly turns into maturity. It germinates later. Angiosperms are flowering seeds, so it is covered by a fruit such as apples. Gymnosperms are unprotected seeds,so there are less possibilities to reproduce than angiosperms. Gymnosperms are usually all spores and there are more gymnosperms than angiosperms because of the possibility of growing.

All pine trees are conifers, which are gymnosperms or "naked seeds" due to the fact that they reproduce by cones instead of by flowers.

Both have a dormant stage called a sporophyte Both reproduce using seeds Both are vacular plants

Yes, gymnosperms DO have leaves.

Some things which reproduce asexually:some kinds of worms (eg. earthworms)some kinds of snailSome kinds of insectsmushroomfungibacteriaSome things which reproduce sexually:MammelsMost reptilesPlants (most gymnosperms and angiosperms)

both are seed plants and seed plants share two characteristics: having vascular tissue and uses seeds to reproduce
