Solution and Explanation
Refer to the labelled diagram below for the stages of embryonic development in a dicot plant:
- The embryonic development in dicots progresses through distinct stages:
- Globular stage: A spherical mass of cells forms.
- Heart-shaped stage: Cotyledons begin to emerge, giving the embryo a heart shape.
- Torpedo stage: The cotyledons elongate, and the shoot and root meristems become prominent.
- Mature embryo stage: The embryo has two cotyledons, a plumule (shoot tip), and a radicle (root tip), ready for germination.
