Q. Embryology in relation to taxonomy?

Embryological information has been used for taxonomic purposes at various levels of classification. You know of a very basic division of the plant kingdom into 2 units; the Thallophytes and the Embryophyta where plants are recognised on the basis of the behaviour of the zygote in addition to other characters.

1. Anther
2. Quadripartition of the microspore mother cell.
3. Pollen grain.
4. Development and structure of the ovule.
5. Origin and extent ,of the sporogenous tissue in the ovule.
6. Megasporogenesis and development of the embryo sac.
7. Form and organisation of the mature embryo sac.
8. Fertilisation.
9 .' Endosperm.
10. Embryo.
11. Seed-coat.
12. Special features.

In the same way you are also aware that the characters of the embryo along with several other features provide the basis for the division of the angiosperms into 2 major groups, the monocotyledons and the dicotyledons.
