NEET BIOLOGY

Detailed explanation-1: -Plants have two transport systems-xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.

Detailed explanation-2: -In plants, the transport system consists of tube like passages made up of vascular tissue. There are two types of vascular tissues in plants-xylem and phloem.

Detailed explanation-3: -The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.

Detailed explanation-4: -Plants have two transport tubes to transport food and water throughout the plant.

Detailed explanation-5: -Pneumatic tubes (or capsule pipelines, also known as pneumatic tube transport or PTT) are systems that propel cylindrical containers through networks of tubes by compressed air or by partial vacuum. They are used for transporting solid objects, as opposed to conventional pipelines which transport fluids.
