AP BIOLOGY

Detailed explanation-1: -The tubers originate from the swollen ends of stolons. At the farthest point away from stolon attachment and tuber, the terminal bud is produced. The bud shows apical dominance as a normal stem. The tuber is the vegetative propagation part of the potato.

Detailed explanation-2: -The potato tuber is an enlarged portion of an underground stem or stolon (Figure 1.1-1). Tuber eyes are the buds from which next season’s growth will emerge. Eyes are concentrated near the apical end of the tuber, with fewer near the stolon or basal end.

Detailed explanation-3: -A tuber is a plant that mainly grows underground. Potatoes and yams are tubers-and they’re delicious with a little butter and salt. The part of a potato plant that can be eaten is its thickened underground stem-and officially, that’s the part of the plant considered a tuber.

Detailed explanation-4: -The sink organs of potato are the underground tubers, and the source organs are its leaves (Fig.

Detailed explanation-5: -The tuber is modified for the storage of food. Potato grows on the underground stem. This stem is known as stolon.
