Question

It is easier to pull out a wheat or maize plant, but it is difficult to pull out a tomato or brinjal plant. Why is it so?

Answer 1

Roots:

1. The roots of the plants attaches the plant in the soil.
2. Tomato and brinjal are dicot plants which have taproots.
3. Taproots bear a main thick root and many side branches which firmly attaches the plant in the soil.
4. Wheat and maize are monocot plants which have fibrous roots.
5. Fibrous roots are formed in clusters and do not attach the plant as strongly as taproots.
6. Therefore, it is easy to pull out a wheat or maize plant than to pull out tomato or brinjal.

Final answer: It is easy to pull out a wheat or maize plant than to pull out tomato or brinjal due to presence of strong taproots.
