Question:
In the given diagram of developing monocot embryo, identify the labels 'i', 'ii' and 'iii'.
In the given diagram of developing monocot embryo, identify the labels 'i', 'ii' and 'iii'.
Show Hint
The embryo develops with a suspensor on top, and the cells next to it form the root tip.
Updated On: Nov 13, 2026
i - Radicle, ii - Suspensor, iii - Cotyledon
i - Cotyledon, ii - Suspensor, iii - Radicle
i - Suspensor, ii - Cotyledon, iii - Radicle
i - Suspensor, ii - Radicle, iii - Cotyledon
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
The diagram shows a young embryo in which the large basal cell lies on top, followed by a short row of cells and then the mass of embryo cells.
Step 2: Identify labels
The large cell and its connection to the embryo is the suspensor region (i).
The small cells just below it (the hypophysis) give rise to the radicle (ii).
The large mass of cells at the bottom develops into the cotyledon and plumule region (iii).
Step 3: Conclusion
The labels are i - Suspensor, ii - Radicle, iii - Cotyledon.
Final Answer:
Label i is the suspensor, ii the radicle and iii the cotyledon. \[ \boxed{\text{(D) }\text{i - Suspensor, ii - Radicle, iii - Cotyledon}} \]
