Question
How is food transported in plants?
✓
Answer
The transport of soluble products of photosynthesis is called translocation.
$\rightarrow$ Translocation occurs in the part of the vascular tissue known as phloem.
$\rightarrow$ Besides, the products of photosynthesis, the phloem transports amino acids and other substances. These substances are especially delivered to roots, fruits, seeds and to growing organs where it is stored.
$\rightarrow$ The translocation of food and other substances takes place in the sieve tubes with the help of adjacent companion cells both in upward and downward directions.
$\rightarrow$ The translocation in phloem is achieved by utilising energy.
$\rightarrow$ Sucrose (Sugar/Carbohydrate) is transferred into phloem tissue using energy from ATP. This increases the osmotic pressure of the tissue causing water to move into it.
$\rightarrow$ This pressure moves the material in the phloem to tissues having less pressure. The phloem thus moves material according to the plant's need.
e.g., In the spring, sugar stored in root or stem tissue is transported to the buds which need energy to grow.
