Question

which Complex permanent tissue conduct material in both direction define it​

Answer 1

plant tissue is of two type :---

1. complex tissue
2. permanent tissue

• complex tissue :- it is subdivided in to xylem and phloem made up of number of cell .It's function is of transportation of food and water from root to different part of plants .
• permanent tissue :---it is subdivided in to colenchyema,sclranchyema and parenchyma .

Answer 2

Answer:

Complex permanent tissues are conducting tissues, which take part in the transport function of plants. They are of two types– xylem (which transports water), and phloem (which transports food materials). The presence of this vascular tissue is an important feature of all complex terrestrial plants.

Xylem comprises of the following:

Xylem vessels and tracheids are tubular structures, which allow vertical transport of water and minerals. Vessel cells are continuous, while tracheids are discontinuous. They are both conductive tissues.

Xylem parenchyma stores food and conducts water sideways.

Xylem fibres are supportive in function.

Phloem comprises of the following:

Sieve tubes are tubular cells with perforated walls.

Companion cells are elongated cells, which are always associated with sieve tubes. They perform metabolic functions and helps in water translocation.

Phloem parenchyma is a cell associated with the phloem tissue. They pack other types of cells together.

Phloem fibres are non-living cells.
