Question

name two gymnosperm species used for food​

Answer 1

Answer:

Cycads, Ginkgo, and gnetophytes

Answer 2

Answer:

Cycads, Ginkgo, and gnetophytes have two cotyledons in the embryo; pine and other conifers may have several (eight is common; some have as many as 18). In cycads and Ginkgo the cotyledons remain within the seed and serve to digest the food in the female gametophyte and absorb it into the developing embryo.
