Transportation of food and other substances in plants :
The food produced in leaves is transported to each cell in the plant body. Excess food,
except amino acids, is stored in roots, fruits and seeds. This process is called 'translocation'
of materials. It is carried out in both the upward and the downward directions by the
phloem. Translocation of materials is not a simple physical process; it requires energy.
This energy is obtained from ATP.
Whenever food material like sucrose is transported towards a part of a plant via the
phloem with the help of ATP, the water concentration decreases in that part. As a result
,
water enters the cell by the process of diffusion. The pressure on the cell wall increases due
to the increase in cellular contents. Due to the increased pressure, food is pushed into the
neighbouring cells where the pressure is low. This process helps the phloem to transport
the materials as per the need of the plant. During flowering season, the sugar stored in
roots or stem is transported towards the floral buds to make them open and blossom.
