Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The vascular tissue in a stem and a leaf is an adaptation for the
A
breakdown of inorganic raw materials
B
transport of nutrients and water
C
regulation of auxin distribution
D
removal of gases from the plant
Explanation: 

Detailed explanation-1: -Vascular tissue transports water, minerals, and sugars to different parts of the plant. Vascular tissue is made of two specialized conducting tissues: xylem and phloem. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem.

Detailed explanation-2: -The vascular adaptation hypothesis proposes that the environment controls the plant’s vascular system through its control of plant’s development, height, and shape. Limiting conditions suppress plant growth and shorten the active growth period, which restrict plant development resulting in small plants.

Detailed explanation-3: -Phloem is the vascular tissue which transports food from leaves to the other parts of the plant. Phloem is composed of various specialized cells called sieve tubes, companion cells, phloem fibers and phloem parenchyma cells.
