What vascular tissue inside a plant carries water from the roots to other parts of the plant?
A.
Phloem
B.
Spores
C.
Xylem
D.
Lignin
Correct Answer
C. Xylem
Explanation Xylem is the correct answer because it is the vascular tissue responsible for transporting water and minerals from the roots to the rest of the plant. It consists of specialized cells called tracheids and vessel elements, which are arranged in a tube-like structure. Xylem plays a crucial role in maintaining the plant's water balance and providing support to the plant.
