Question

Describe the stages in embryo development in a dicot plant.

Answer 1

• The zygote divides into a basal cell and a terminal cell.
• The basal cell forms the suspensor; the terminal cell forms the embryo proper.
• The embryo passes through proembryo, globular and heart-shaped stages, then differentiates into two cotyledons and an embryonal axis bearing plumule, hypocotyl and radicle.
