Question

Photosynthesis takes place in the leaves and the food prepared by it reaches other parts of the plants. Name the process involved and explain it.

Answer 1

Process Involved: Translocation

Explanation:
- Photosynthesis is the process by which green leaves prepare food (mainly glucose) using sunlight, carbon dioxide, and water.
- This food is converted into sucrose (a soluble form of sugar) and needs to be transported from the leaves (source) to other parts of the plant (sinks) like roots, stems, fruits, and growing tissues.

The process of translocation:
- Translocation is the movement of food substances through the phloem tissue of the plant.
- The phloem transports these food materials in both upward and downward directions, depending on the need of the plant.
- This process requires energy in the form of ATP and involves the active transport of sugars into the phloem cells, creating a concentration gradient that drives the flow of materials.

Conclusion:
The food prepared in leaves is distributed to all parts of the plant through a process called translocation, which occurs in the phloem tissue.
