Concept explainers
The plant bodies are made up of three types of essential tissues includes ground, vascular and dermal tissues. The ground tissues make up the majority of plant body and contribute in wound repair and photosynthesis. The dermal tissues regulate the flow of
Answer to Problem 1TQ
The water is transported through the plant body by xylem. Therefore, option (a) is correct.
Explanation of Solution
Justify the reasons for the correct statement:
A type of vascular tissue that present all over the body of the plant is called as the xylem. The essential function of the xylem is to transport the water from the roots to different parts of the plant shoots system such as stems and leaves. It also involved in transporting nutrients.
Option (a) is given as, “xylem”.
Hence, the option (a) is correct.
Justify the reasons for the incorrect statements:
Option (b) is given as, “phloem”.
The phloem is the living tissue that involved in transporting the soluble organic compounds that made during the photosynthesis. The specialized cells present in the phloem helps to transport sugar such as sucrose. Thus, the phloem is a food conducting tissue that is not involved in the transport of water. Hence, it is a wrong answer.
Option (c) is given as, “stomata”.
The pore found in the epidermis of stems, leaves and other organs are called as stomata. It mainly facilitates the gaseous exchange during transpiration. The stomata does not transport the water. Hence, it is a wrong answer.
Option (d) is given as, “root hairs”.
A root hairs is a tube-like outgrowth of a trichoblast. The root hairs increase the surface area of absorption. It is not involved in transporting the water. Hence, it is a wrong answer.
Option (e) is given as, “flowers”.
The flowers are the reproductive structure present in the flowering plants. The natural function of the flower is reproduction. The water is not transported by the flowers. Hence, it is a wrong answer.
Hence, options (b), (c), (d), and (e) are incorrect.
Therefore, the xylem function as the transporting of water and nutrients in upward direction to different parts of the plant body.
