Question

Soil around stem of potato plant is constantly removed from very young stage so that only roots remain in the soil. Potato tubers in plant will be:
A) Larger          
B) Smaller
C) Formed normally
D) not formed

Answer 1

Hint: Before we proceed into the problem, it is important to know the definition of potato tuber.
The underground adaptation of the stem that stores starch is known as a tuber. Its surface has axillary buds, which aid in the development of new plants because they are meristematic in nature. The buds are also called scales or eyes. The buds grow into new plants after sprouting. Watering potatoes frequently is necessary.

Step by step solution:
Most potato tubers in a plant will be small and buried deep in the soil where they will not see much sunlight. As a result, their stalks (soil around them) are constantly being removed very young so that only the roots remain which then concentrate minerals from the surrounding soil.
This helps to promote healthy growth of potatoes since they don't have to compete with other plants for resources or space, as well as ensures that there are enough nutrient uptakes for optimal potato production.
The formation of potato tubers in the plant will not occur if the soil surrounding the stem of the potato plant is continuously removed starting at a very young stage and only roots are left in the soil.
This is so because potatoes have both a tuber and a modified stem.
Therefore, potato tubers in the plant will not form.
Hence, the option D is correct.

NOTE:
If only the roots remain in the soil, tubers are created from the underground branches of the stem. The potato tubers in plants won't form as a result.
