Phloem and xylem are two types of conductive tissues present in plants, which play a fundamental role in the transport of nutrients and essential substances.

 Phloem and xylem are two types of conductive tissues present in plants, which play a fundamental role in the transport of nutrients and essential substances. Below is a brief description of each:

Conductive Tissues

Phloem

1. Function: Transports nutrients produced during photosynthesis (sugars, amino acids, etc.) and other organic compounds from the leaves to the rest of the plant, including the roots.

2. Components: It is composed of living cells, such as sieve elements and sieve tubes, which allow the transport of substances.

3. Characteristics: Phloem is capable of transporting substances in both directions (up and down).

Xylem

1. Function: Transports water and minerals from the roots to the leaves, allowing photosynthesis and plant growth.

2. Components: It is composed of dead cells, such as tracheids and xylem vessels, which form a system of rigid conduits.

 3. Characteristics: Xylem transports substances mainly in one direction (from the roots to the leaves).
