Current Question (ID: 12274)

Question:

Which of the following is incorrect about A, B, C and D: (1) Tap roots of carrot, turnip and adventitious root of sweet potato, get swollen and store food (2) Pneumatophores help to get oxygen for respiration (3) Pneumatophore is found in the plants that grow in sandy soil (4) A, B and C are underground roots but D grows vertically upwards

Options:

1. (1) Tap roots of carrot, turnip and adventitious root of sweet potato, get swollen and store food
2. (2) Pneumatophores help to get oxygen for respiration
3. (3) Pneumatophore is found in the plants that grow in sandy soil
4. (4) A, B and C are underground roots but D grows vertically upwards

Solution:

Correction for C: In some plants such as Rhizophora growing in swampy areas, many roots come out of the ground and grow vertically upwards. Such roots, called pneumatophores, help to get oxygen for respiration.
