Phloem: The Plant's Food Transport System
The primary function of transporting manufactured food (sugars) from the leaves to other parts of the plant is carried out by a complex tissue called Phloem.
Phloem is composed of several types of living cells. The key components involved in food transport are:
- Sieve tubes: These are elongated cells responsible for conducting sugars.
- Companion cells: These cells are closely associated with sieve tubes and provide metabolic support. They are also living cells.
Therefore, the complex tissue that transports food in plants is called Phloem and it consists of living cells like sieve tubes and companion cells.
