Explain the structure and functions of various types of conducting tissue

There are two types of conducting tissues- Xylem and Phloem. These tissues transport water and minerals to all the parts of the plant.

1. Xylem:- Xylem tissue transports water from root to all parts of the plant. It is also called the water conducting tissue. Xylem is made up of Vessels, Tracheids, Fibres and Xylem parenchyma.

conducting tissue

  • Xylem Vessels- Xylem vessels is a series of cells. It joined from end to end form a long tube. vessels does not have living Protoplasm at maturity.
  • Tracheids- It is a long narrow cell. It taper at the end. It also does not have living Protoplasm at maturity.
  • Fibres- Fibres provides strength to the tissue. It also lack living Protoplasm at maturity.
  • Xylem Parenchyma- It is only living component of Xylem. It helps in transportation of water and store food.

2. Phloem:- Phloem transports minerals to the other parts of the plants. It is also called the food conduction tissue. It is made up of Sieve cells, Phloem fibres and Phloem Parenchytma.

conducting tissue

  • Sieve cells- It is an enclosed cell with miute porse. It does not have nucleus at maturity. It transports food to the other parts of the plants.
  • Phloem fibres- It provides mechanical strength to the plants.
  • Phloem Parenchyma- It involved in the storage of reserve substances.

Xylem and Phloem tissues together are also called the Vascular  bundle.
