Transport In Plants — Flashcards

Answer

Transportation in plants is the process in which substances absorbed or made in one part of the plant are moved to other parts of the plant. It helps water, minerals, and food reach the parts that nee…

Answer

Xylem and phloem together form the vascular bundle. This conducting system helps the plant move water, minerals, and food through the root, stem, branches, and leaves.

Answer

Xylem is a vascular tissue that transports water and mineral salts from the roots to the aerial parts of the plant. It also gives mechanical strength because some of its cells are strong and thick-wal…

Answer

The four types of xylem cells are xylem tracheids, xylem vessels, xylem parenchyma, and xylem sclerenchyma. Tracheids and vessels conduct water, xylem parenchyma stores food and helps in transport, an…

Answer

Xylem tracheids are elongated dead cells with tapering ends and pitted thickened walls. They help conduct water upwards and also provide mechanical strength to the plant.

Answer

Xylem vessels are tube-like dead structures open at both ends and placed one above the other to form long channels. They conduct water upwards and also provide mechanical support.

Answer

Xylem parenchyma consists of small, thick-walled, living cells. These cells store food and also help in the conduction of water and mineral salts.

Answer

Xylem sclerenchyma, also called wood fibres, consists of thick-walled, long, narrow dead cells with tapering ends. Their main role is mechanical support.
