no
by spores
Plants belonging to bryophytes and Pteridophytes etc. reproduce with spores and thoseof gymnosperms and angiosperms reproduce with seeds.
in broad terms they are spermatophyte's
Through spores and seeds
The saffron crocus is infertile, but gets by in dividing the bulb. No doubt there are many more.Various plants such as red rose, jasmine, grass etc. do not reproduce by seeds.There are also spore-bearing plants like ferns. Those spores are not the same as seeds.
they have seeds
seeds
Yes they do. They make seeds or spores from which new plants grow.
While they have the same function- to reproduce- the main difference between seeds and spores is that seeds come from flowering plants (they are the ripened ovules of the plants) and spores are produced by non-flowering plants (they are tiny reproductive bodies). Seeds, since they are ripened ovules, have plant embryos with a food store and a protective covering around all of that. On the other hand, spores do not have stored food resources and can be made of one or many cells. So, seeds are multicellular while spores are usually unicellular, and seeds contain embryonic plants while spores do not (they themselves are the tiny reproductive bodies).
Not all plants do actually. Most Vascular Plants ( plants with tubes ) have seeds. Some plants have spores instead of seeds.
plants need spores pollen and seeds to reproduce
