TRANSPORT IN PLANTS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ are tubes that carry nutrients to other parts of the plant.
A
stomata
B
roots
C
xylem
D
xylophone
Explanation: 

Detailed explanation-1: -The two primary vascular tissues are xylem, which transports water and dissolved minerals from the roots to the leaves, and phloem, which conducts food from the leaves to all parts of the plant.

Detailed explanation-2: -The vascular system is comprised of two main types of tissue: the xylem and the phloem. 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-3: -The xylem transports water and minerals from the roots up the plant stem and into the leaves. In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels. Vessels: Lose their end walls so the xylem forms a continuous, hollow tube.

Detailed explanation-4: -Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.

Detailed explanation-5: -xylem tracheids. The xylem tracheary elements consist of cells known as tracheids and vessel members, both of which are typically narrow, hollow, and elongated. Tracheids are less specialized than the vessel members and are the only type of water-conducting cells in most gymnosperms and seedless vascular plants.
