Question

Select the statements that are true for a typical dicotyledonous embryo from the given options.

• A. It consists of an embryonal axis and scutellum.
• B. (i) and (ii)
• C. (i) and (iii)
• D. (iii) and (iv)

Hint:

Dicot embryos have two cotyledons, an epicotyl, a radicle with root cap, and lack structures like coleorhiza and scutellum that are found in monocots.

Answer 1

The Correct Option is D

In a typical dicot embryo:
- Statement (ii) is correct: The epicotyl is the part of the embryonal axis above the level of cotyledons and gives rise to the shoot system.
- Statement (iv) is correct: The radicle is the embryonic root, and it is covered by a root cap.
- Statement (i) is incorrect because scutellum is a feature of monocot embryos, not dicots.
- Statement (iii) is incorrect as coleorhiza is also a monocot feature.
