Detailed explanation-1: -Xylem is a type of vascular tissue present in plants, which primarily transports water and nutrients from roots to stem and leaves. They also provide mechanical strength to the plants.
Detailed explanation-2: -Xylem is the tissue of vascular plants that transports water and nutrients from the soil to the stems and leaves. Xylem plays an essential ‘supporting’ role providing strength to tissues and organs, to maintain plant architecture and resistance to bending.
Detailed explanation-3: -Both lignin and cellulose are found in the rigid cell walls of the xylem cells (those that conduct water) in the primitive plant Selaginella.
Detailed explanation-4: -Reason (R): Xylem parenchyma cells are living and thin walled. The main function of xylem parenchyma is to store starch and fatty substances.
Detailed explanation-5: -The correct answer is Transport of water from roots to leaves. Xylem is a type of tissue in vascular plants that transports water and some nutrients from the roots to the leaves.
