Question

Heart shaped embryo is the feature of:

• A. Dicots
• B. Monocots
• C. Both of these
• D. None of these

Hint:

Monocots do not show a distinct heart-shaped stage because they only develop a single cotyledon (scutellum).

Answer 1

The Correct Option is A

Step 1: During embryogeny in dicotyledonous plants, the zygote gives rise to the proembryo.
Step 2: The development follows a specific sequence of shapes: Globular $\rightarrow$ Heart-shaped $\rightarrow$ Mature embryo.
Step 3: The two "lobes" of the heart eventually develop into the two cotyledons characteristic of dicots.
