Match List - I with List - II.
| List - I | List - II |
|---|---|
| Name of the part | characteristics |
| A. Non-albuminous seed | I. Residual endosperm present |
| B. Albuminous seed | II. Fruit wall |
| C. Perisperm | III. Residual endosperm absent |
| D. Pericarp | IV. Residual nucellus |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A-III, B-I, C-IV, D-II
(A) Non-albuminous seed — this matches (III) Residual endosperm absent. The endosperm is used up by the embryo, as in pea and groundnut.
(B) Albuminous seed — this matches (I) Residual endosperm present. Part of the endosperm remains, as in wheat, maize and castor.
(C) Perisperm — this matches (IV) Residual nucellus. In black pepper and beet the nucellus persists.
(D) Pericarp — this matches (II) Fruit wall. The wall of the ovary becomes the fruit wall.
NCERT Extract:
Seed – “… Mature seeds may be non-albuminous or ex-albuminous. Non-albuminous seeds have no residual endosperm as it is completely consumed during embryo development (e.g., pea, groundnut). Albuminous seeds retain a part of endosperm as it is not completely used up during embryo development (e.g., wheat, maize, barley, castor). Occasionally, in some seeds such as black pepper and beet, remnants of nucellus are also persistent. This residual, persistent nucellus is the perisperm.”
Seed – “… The wall of the ovary develops into the wall of fruit called pericarp.”
