प्रश्न
How is food transported in plants?
उत्तर १
Phloem transports food materials from the leaves to different parts of the plant. The transportation of food in phloem is achieved by utilizing energy from ATP which helps in creating osmotic pressure that transports food from the area of high concentration to low concentration.
उत्तर २
- The transport of food from the leaves to the other parts of the plant occurs through the vascular tissue called phloem. The food (sugar) made in leaves is loaded into the sieve tubes of phloem tissue by using the energy derived from ATP.
- As a result, the osmotic pressure in the tissue increases, causing the water to move into it. This high pressure produced in the phloem, moves the food to all the parts of the plant that have less pressure in their tissues. This process is helpful in moving the food materials according to the needs of the plant.

The transport system in plants consists of two kinds of tissues X and Y. The tissue X is made up of living cells and consists of two components A and B. The component A has tiny pores in its end walls and contains only cytoplasm but no nucleus. On the other hand, component B has cytoplasm as well as nucleus. The tissue Y is made up of dead cells and consists of two components C and D. The component C has open ends whereas component D does not have open ends. In flowering plants, either only C or both C and D transport water but D is the only water conducting tissue in non-flowering plants.
