Transportation in Plants Biology Class 6th to 10th  Revision of  Chapters

Vascular tissues are tissues that conduct water, minerals and nutrients throughout the plant body in higher plants.

Xylem is a conducting tissue for water and minerals from roots to various parts of plant body.

Transpiration is a process in which water evaporated from leaves through stoma.

Root pressure is a phenomenon to absorb water from soil.

Guttation is appearance of xylem sap drops on tips and margins of leaves.

Translocation is transport of nutrients from leaves to other parts of plant body.

Phloem is a conducting tissue for nutrients from leaves to other parts of plant body.

Active transport is transport of a substance across a cell membrane against the concentration gradient, requires an expenditure of energy.

Xylem tissue is present in the roots, stems and leaves. It has four different types of cells: tracheids, vessels, xylem fibers and xylem parenchyma. The xylem transports water and minerals from the roots to the leaves.

Tracheids and vessels are interconnected to form a continuous system of water-conducting channels that reach all parts of a plant.

Cells in the roots take up ions to create a high ion concentration. This causes water to move into the roots

Transpiration is the process of loss of water from a plant's body. It causes the movement of water and dissolved minerals from the roots to the leaves through the xylem.

Translocation is the process of the movement of dissolved substances from the leaves to the roots and other parts of a plant's body through the phloem.

The phloem is a conducting tissue for nutrients from the leaves to the other parts of a plant's body. The phloem is made of four types of cells: sieve tubes, companion cells, phloem fibres and phloem parenchyma.

Translocation takes place in the sieve tubes, with the help of adjacent companion cells.

Glucose molecules in the leaves are transferred to the phloem tissue using energy from ATP. This process is called active transport.
