Question

The process in which transport of soluble products of photosynthesis takes place in plants is known as:

• A. Transpiration
• B. Evaporation
• C. Conduction
• D. Translocation

Answer 1

The Correct Option is D

Step 1: Understand the products of photosynthesis
Photosynthesis in green plants produces glucose (a type of sugar), which is later converted into sucrose—a soluble form that can be easily transported.

Step 2: What needs to be transported?
The soluble products like sucrose, amino acids, and other organic nutrients need to be transported from the leaves (site of photosynthesis) to other parts of the plant such as roots, stems, fruits, and growing tissues.

Step 3: Name of the process
The movement of these soluble products through the phloem tissue is called translocation.
It occurs in both directions—upward and downward—depending on the plant’s needs.

Step 4: Why is it important?
Translocation is essential for the proper growth and development of plants. It ensures that food produced in leaves reaches all parts of the plant, including storage organs and growing regions.

Final Answer:
Translocation
