Difference between angiosperm frtilisation and gymnosperm fertilisation

Answer 1

angiosperms also called flowering plants have seeds that are enclosed within an ovary usually a fruits , while gymnosperms have no flowering or fruits and have unenclosed or naked seeds on the surface of scales or leaves . ... I hope this help you.... mark me as brainlist

Answer 2

. In gymnosperms the reproductive structures are cones which are unisexual

2. The ovules are exposed, i.e., they are not located in the ovary.

3. After fertilization, the ovules develop into naked seeds.

4. The microspores and megaspores are produced by male and female cones

5. The pollen grains fall and germinate directly on the micropyle of the ovules

6. Fertilization is simple

7. Endosperm is haploid

8. In gymnosperms the pollination is by wind alone

9. In gymnosperms, generally the xylem contains only tracheids. Vessels are absent

10. The phloem has no companion cells

Angiosperms

1. In Angiosperms, the flowers are the reproductive organs and they may be both unisexual and bisexual.

2. The ovules are enclosed in the ovary.

3. After fertilization, the ovules develop into seeds inside the fruit.

4. The microspores are produced in anthers while the megaspores are produced in ovules of the ovary in flowers

5. The pollen grains fall on the stigma, germinate and the pollen tube carries the male gamete to the ovary

6. Fertilization is double

7. Endosperm is triploid

8. In angiosperms, different agents like wind, insects, bats etc are involved in pollination

9. Angiosperms vessels are always are present

10. Companion cells are present
