Question

In plants, food is transported through
A. Phloem parenchyma
B. Xylem parenchyma
C. Xylem
D. Phloem

Answer 1

Transportation is an important function in all living organisms because it allows water, minerals, and other essential nutrients to reach all areas of the plant. The process of transporting food from the leaves to other areas of the plant is known as translocation.
Water is the most significant barrier in plant transportation since it is a growth limiting factor. Trees and other plants have the perfect system for water absorption and transport to solve this problem.

Complete answer:
Option A: The phloem parenchyma stores food as well as other compounds like resins, latex, and mucilage. They also aid in food's delayed lateral conduction.
So option A is not correct.
Option B: The storage of dietary material in the form of carbohydrates, lipids, tannins, and crystals is one of the key roles of the xylem parenchyma. The ray parenchymatous cell is responsible for water radial conduction.
So option B is not correct.
Option C: The vascular plant's xylem is the tissue that transfers water and nutrients from the soil to the stems and leaves. The Supporting' role of xylem is to provide strength to tissues and organs, as well as to maintain plant architecture and resistance to bending.
So option C is not correct.
Option D: The phloem transports food within the plant.
The vascular tissue responsible for transporting sugars from source tissues to sink tissues is referred to as phloem. The phloem also transports other compounds such as proteins and mRNAs throughout the plant.

So option D is the correct answer.

Note:
The synthesised food molecules by the leaves are delivered to the various storage organs in plants, such as the roots, stems, and fruits, via vascular tissue called phloem.
Functions of phloem-
1. Food supplies are transported from the leaves to other sections of the plant with the help of phloem.
2. Food is transported both upwards and downwards through phloem.
3. Transportation necessitates the use of ATP as a source of energy.
