CBSE Class 10 Science 2022 · Paper 31/2/2 · Question 5
In the following figure showing a germinating gram seed, name the parts labelled as A, B and C :
Why is part ‘B’ considered to be important during germination ?
Answer
A is the plumule, B the cotyledon and C the radicle; the cotyledon is important as it stores food for the germinating seed.
A – Plumule (grows into the shoot); B – Cotyledon (the seed leaf that stores food); C – Radicle (grows into the root).
Part B, the cotyledon, is important because it stores food: during germination the growing plumule and radicle use this food, and they depend on it until the seedling has green leaves and can make its own food by photosynthesis.
