BOTANY

Detailed explanation-1: -The stem conducts water and nutrient minerals from their site of absorption in the roots to the leaves by means of certain vascular tissues in the xylem. The movement of synthesized foods from the leaves to other plant organs occurs chiefly through other vascular tissues in the stem called phloem.

Detailed explanation-2: -The stem is the part of the plant which develops from the shoot after germination. Its main function is to help in the movement of water which is absorbed by the roots to different parts of the plant. The stem provides support to the plant and helps in keeping the plant erect.

Detailed explanation-3: -(i) It supports branches, leaves, flowers, and fruits. (ii) It transports water and minerals from the roots to the leaves and other parts of plants. (iii) It transports food from leaves to different parts of the plant. (iv) It holds the plant upright.

Detailed explanation-4: -Xylem transports water, minerals, and nutrients from the soil to all the plant parts. There are two types of “transport” tissues in plants-xylem and phloem. Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem.

Detailed explanation-5: -Support: Primary function of the stem is to hold up buds, flowers, leaves, and fruits to the plant. Along with the roots, a stem anchors the plants and helps them to stand upright and perpendicular to the ground.
