Question

Both gymnosperms and angiosperms bear seeds, then why are they classified separately?​

Answer 1

.’Gymnosperms and angiosperms both bear seeds but they are classified separately because gymnosperms are a group of plants in which the ovules are freely exposed on open megasporophylls, whereas in angiosperms the seeds or ovules are enclosed within ovary which later forms the fruit.

Answer 2

Answer:

Following are the reasons for classifying Angiosperms and Gymnosperms separately.

• In gymnosperms, ovules are naked whereas they are enclosed inside the ovary in angiosperms

• In Gymnosperms endospore is haploid and produced before fertilization whereas in Angiosperms endosperm is triploid and formed after double fertilization.

• In Gymnosperms double fertilization does not occur, but in Angiosperms, double fertilization occurs.

• In gymnosperms, wood is nonporous and in angiosperms wood is porous.
