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:
- Green leaves produce food (primarily glucose) through photosynthesis, utilizing sunlight, carbon dioxide, and water.
- This food is converted to sucrose, a soluble sugar, which must be moved from the leaves (source) to other plant parts (sinks) such as roots, stems, fruits, and developing tissues.

The process of translocation:
- Translocation is the transport of food substances via the plant's phloem tissue.
- The phloem moves these food materials both upwards and downwards, based on the plant's requirements.
- This process is energy-dependent, utilizing ATP. It involves the active transport of sugars into phloem cells, establishing a concentration gradient that facilitates the movement of materials.

Conclusion:
Food manufactured in leaves is distributed throughout the plant via a process known as translocation, which takes place within the phloem tissue.
