Morphology of the potato plant; tubers are forming from stolons. Potato plants are herbaceous perennials that grow up to 1 metre (3.3 ft) high. The stems are hairy. The leaves have roughly four pairs of leaflets. The flowers range from white or pink to blue or purple; they are yellow at the centre, and are insect-pollinated.
Thirdly, plant morphology studies plant structure at a range of scales. At the smallest scales are ultrastructure, the general structural features of cells visible only with the aid of an electron microscope, and cytology, the study of cells using optical microscopy. At this scale, plant morphology overlaps with plant anatomy as a
Some plants also form smaller tubers or tubercules that act like seeds, producing small plants that resemble (in morphology and size) seedlings. Some stem tubers are long-lived, such as those of tuberous begonias , but many plants have tubers that survive only until the plants have fully leafed out, at which point the tuber is reduced to a ...
The potato tuber moth (Phthorimaea operculella) is an oligophagous insect that prefers to feed on plants of the family Solanaceae, especially the potato plant (Solanum tuberosum). Female P. operculella use the leaves to lay their eggs and the hatched larvae will eat away at the mesophyll of the leaf. After feeding on the foliage, the larvae ...
Non-vascular plants , with their different evolutionary background, tend to have separate terminology. Although plant morphology (the external form) is integrated with plant anatomy (the internal form), the former became the basis of the taxonomic description of plants that exists today, due to the few tools required to observe.

These potatoes also have coloured skin, but many varieties with pink or red skin have white or yellow flesh, as do the vast majority of cultivated potatoes. The yellow colour, more or less marked, is due to the presence of carotenoids. Varieties with coloured flesh are common among native Andean potatoes, but relatively rare among modern varieties.
Solanum is a large and diverse genus of flowering plants, which include three food crops of high economic importance: the potato, the tomato and the eggplant (aubergine, brinjal). It is the largest genus in the nightshade family Solanaceae , comprising around 1,500 species.
Flowering plants often produce no stolons. [19] Convolvulus arvensis is a weed species in agriculture that spreads by under ground stolons that produce rhizomes. [20] In studies on grass species, with plants that produce stolons or rhizomes and plants that produce both stolons and rhizomes, morphological and physiological differences were noticed.
