Question

Which embryo (X or Y) is likely to develop into a normal dicot embryo?

Hint:

Asymmetry is crucial for establishing the polarity of the plant body.

Answer 1

Step 1: Understand the structure of a normal dicot embryo.
A normal dicot embryo consists of two cotyledons and has distinct parts such as the plumule (embryonic shoot), radicle (embryonic root), and hypocotyl. The embryo develops in a well-organized pattern where the cotyledons are clearly visible and symmetrically arranged.

Step 2: Identify the correct embryo structure.
Among the two embryos shown (X and Y), the embryo that shows two well-developed cotyledons and a properly differentiated embryo axis represents the typical structure of a dicot embryo.

Step 3: Determine the correct option.
Embryo X shows the proper dicot embryo structure with two cotyledons and a clearly defined embryo axis, while embryo Y does not show this normal organization.

Final Answer:
The embryo likely to develop into a normal dicot embryo is X.
