Question

Differentiate between any two of the following:
(i) Hypocotyl and Epicotyl
(ii) Perisperm and Pericarp
(iii) Integument and Testa

Hint:

Hypocotyl → root part, Epicotyl → shoot part. Perisperm → nucellus, Pericarp → ovary wall. Integument → ovule covering, Testa → seed coat.

Answer 1

(i) Difference between Hypocotyl and Epicotyl:\[\begin{array}{|c|c|} \hline Hypocotyl & Epicotyl \\ \hline \text{Part of the embryonic axis below the cotyledons.} & \text{Part of the embryonic axis above the cotyledons.} \\ \hline \text{Develops into the radicle (root system).} & \text{Develops into the plumule (shoot system).} \\ \hline \text{Example: Elongates during germination in dicots like bean.} & \text{Example: Gives rise to stem and leaves.} \\ \hline \end{array}\](ii) Difference between Perisperm and Pericarp:\[\begin{array}{|c|c|} \hline Hypocotyl & Epicotyl \\ \hline \text{Part of the embryonic axis below the cotyledons.} & \text{Part of the embryonic axis above the cotyledons.} \\ \hline \text{Develops into the radicle (root system).} & \text{Develops into the plumule (shoot system).} \\ \hline \text{Example: Elongates during germination in dicots like bean.} & \text{Example: Gives rise to stem and leaves.} \\ \hline \end{array}\](iii) Difference between Integument and Testa:\[\begin{array}{|c|c|} \hline Hypocotyl & Epicotyl \\ \hline \text{Part of the embryonic axis below the cotyledons.} & \text{Part of the embryonic axis above the cotyledons.} \\ \hline \text{Develops into the radicle (root system).} & \text{Develops into the plumule (shoot system).} \\ \hline \text{Example: Elongates during germination in dicots like bean.} & \text{Example: Gives rise to stem and leaves.} \\ \hline \end{array}\]
