Answers
Answer:
1) Root, in botany, that part of a vascular plant normally underground. ... Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.
2) Stem. It functions as a skeleton by constituting a major part of the shoot system and firmly supports the other components like leaves, buds, flowers and fruits. The main stem originates through the direct prolongation of tigellum of the embryo and gives rise to the lateral stems, comprising leafy appendages, buds etc.
3)Taproot penetrates deep into the soil, while a fibrous root is shallow and does not penetrate as deeply. A taproot is the differentiated primary root of the plant, while the fibrous root is not the differentiated primary root of thethe plant, while the fibrous root is not the differentiated primary root of the plant. ... Taproot is found in dicots, while a fibrous root is found in monocots.
4) Each leaf typically has a leaf blade (lamina), stipules, a midrib, and a margin. Some leaves have a petiole, which attaches the leaf to the stem; leaves that do not have petioles are directly attached to the plant stem and are called sessile leaves.
