Circulatory System in Plants

Circulatory System

Plants, like animals, also have a circulatory system.

Circulatory System

• 2 separate sets of tubes that run through the leaves, stems and roots.

• xylem, phloem.

Circulatory System

• xylem tubes turned red when placed in water containing food dye.

Circulatory System

The phloem tubes carry food made in the leaves to the other parts of the plants.

Circulatory System

• food made in the leaves transported to all parts of the plant by phloem

•water and dissolved mineral salts absorbed by the roots must be carried to all parts of the plant by xylem

• To anchor plant in the soil

• To absorb minerals and water from the soil

• To store food

• Roots form a passage way for water and dissolved substances from the root into the stem and also for foods from the stem down into the root.

Function of root

Function of root hair

• To increase the area of absorption

• layer of active dividing cells between the xylem and phloem

• To absorb minerals and water from the soil

• divide to form secondary xylem and phloem

• Roots form a passage way for water and dissolved substances from the root into the stem and also for foods from the stem down into the root.
