Question

Arrange the stages of embryo development in dicots from earliest to latest.

• A. Heart-shaped
• B. Mature
• C. Pro-embryo
• D. Globular

Answer 1

In dicots, the zygote develops into an embryo at the micropylar end. Zygote gives rise to the proembryo and subsequently to the globular stage which later forms a cordate shaped or heart-shaped embryo. Further development of the heart shaped embryo leads to the mature embryo stage.
