What is phloem tissue? Phloem contains two types of cells joined side by side. Name these two types of cells. State whether these cells are living or dead.

Phloem is a conducting tissue in plants, which helps in the translocation of the food prepared in the leaves to all the other parts of the plant. Sieve tubes and companion cells are components of Phloem tissue. These cells are living cells.

BiologyClass 10ICSE

What is xylem tissue? Name the two kinds of cells in xylem tissue. State whether these cells are living or dead.

Xylem is a conducting tissue in plants, which helps in the translocation of water and minerals. These are absorbed from the soil by the roots of the plants, to transport to various parts of the plant such as stems, leaves and flowers. The two kinds of cells in xylem tissue are xylem vessels and tracheids. These cells are dead cells.
