Question

What is the eye of a potato?
A. Axillary bud
B. Accessory bud
C. Adventitious bud
D. Apical bud

Answer 1

Hint: Potato is the one of tuber bearing species of Solanum genus. This tuber bear spirally arranged as a bud in the axils of aborted leaves. This bud is called the eyes of a potato. If the potato is left for too long then the sprout will grow on it. So it is called the eye. Before growing the sprout it can be easily identified that the surface of the potato will look like a dry nub sticking straight out from the potato. So the sprout is the reason for growing new potatoes on it.

Complete explanation:
Option A: Axillary bud is formed in between the leaf and stem. Shoot apex is inhibiting outgrowth of axillary buds. This process is called apical dominance. The first leaf primordial develops into scales and forms an axillary bud. This is an embryonic or organogenic shoot which was located in the axil of the leaf. So every bud has potential to form shoots and it will produce either vegetative shoots or reproductive shoots. So it is the reason for new sprout growth. So it looks like the eye of a potato.
Hence Option A is correct.
Option B: Accessory bud is growing near the bud and it is in addition to the normal axillary bud. It occurs near the axillary bud. This bud is the source of new growth of buds when the primary bud is damaged by the frost or some external factors.
Hence Option B is incorrect.
Option C: Adventitious bud grows except the leaf axils, stem tips and plant apices. It is produced at the leaf notches. It is used for the vegetative propagation. It is formed after the stem is wounded. It is used to replace the lost branches.
Hence Option C is incorrect.
Option D: Apical bud located at the apex of the stem. This bud is called the dominant bud over all the buds. It is the main area of growth in more plants. It produces the hormone called auxin. It is the reason for the growth of lateral buds.
Hence Option D is incorrect.

Hence, Option A is the correct answer.

Note:
Potato eyes look like a simple dimple on the surface of potatoes. Both stems and roots sprout in the potato. Most of the seed potatoes or small whole potatoes have at least two eyes. The food in the seeds is reserved. Each tuber or potato has several buds. It looks like small eyes. Due to the potato's dormancy period this eyes of potatoes will produce. Unfavorable weather conditions are the reason for sprouting. Because during the long storing time of potatoes it will break the dormancy. So the sprout is produced.
