Biology - Xylem and Phloem
Xylem- transports water and minerals upwards from the roots. The dead cells of xylem (tracheids and vessels) are joined end to end forming long tubes , which conduct water along the length of the plants Phloem - transfers food made in the leaves to all parts of the plant. The sieve cell of food Phloem tissue also from long tubes for translocation of food . At maturity , sieve cells lack a nucleus and have very few organelles to allow translocation of food molecules
Biology- Absorption of water and minerals in plants: OSMOSIS
The movement of water molecules from the region of its higher concentration to the region of its lower concentration when both are separated from a semi permeable membrane is called osmosis . i.e. the water molecules from the soil (higher concentration) are absorbed by the root hairs of plant (lower concentration) through the process of osmosis.
