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.
