Question

write a note on the complex tissue which conducts water

Answer 1

the complex tissue which conducts water in plants known as xylem.
They transport water and mineral from roots to various plant parts.
in xylem transport of material takes place through vessels and tracheids which are dead tissues. xylem provides upward movement of water and dissolved materials mainly achieved by transportational pull it is caused due to Saksham created by evaporation of water molecules from their stomata of leaves.
movement of water in xylem is achieved by simple physical process there is no expenditure of energy so ATP molecules are not required for this.

✔✔Tissues composed of more than one type of cells are called complex permanent tissues. There are two types of complex permanent tissues:- 

⭕Xylem - Xylem is a vascular and mechanical tissue. it is composed of four different types of cells:- Tracheids, Vessels, Xylem parenchyma, Xylem sclerenchyma.
The cells have thick walls and many of them are dead cells. Tracheids and vessels are tubular structure. This allows them to transport water and Minerals vertically. The parenchyma stores food and helps in sideways conduction of water.

⭕Phloem - Phloem is made up of four types of elements:- Sieve tubes, Companion cells, Phloem Parenchyma and Phloem fibres. Except from phloem fibres phloem cells are living cells. Sieve tubes are tubular cells with perforated by numerous pores and are called sieve plates. Phloem transports food leaves to other plants of the plant.
