Question

What is a complex permanent tissue? Write the different types of complex permanent tissues.

Answer 1

Hint: Tissues that have reached full maturity and lost their ability to divide are known as permanent tissues. When meristematic tissues divide and differentiate, permanent tissues are created.
Simple permanent tissue- Based on their function, they are classed as sclerenchyma, collenchyma, or parenchyma.
Complex permanent tissue- Phloem and xylem are examples of these tissues. Water and soluble ingredients are transported by xylem, which is very useful. The xylem parenchyma, fibres, vessels, and tracheids make up this structure. Phloem plays an important role in the movement of food particles.

Complete answer:
Complex permanent tissues are made up of a variety of cell types that work together to achieve a specific purpose. Because they participate in the transport of many chemical compounds inside the plant body, complex permanent tissues are also known as conducting tissues of vascular tissues. There are two types of permanent complex tissues.
Xylem- Xylem is important for transporting water and nutrients from the roots to the plant's leaves, as well as providing support. Tracheids, vessels, xylem fibre, and xylem parenchyma are the different types of xylem.
Phloem- It's also known as bast, and it's in charge of transporting ready-to-eat organic food from the leaves to other sections of the plant. Sieve tubes, companion cells, phloem parenchyma, and phloem fibres make up phloem.

Note:
Protective tissues-
Epidermis- The epidermis is a layer of cells that forms the outer coating for all of the plant's components. At some points, the stomata perforate the epidermis. Stomata aid in water loss and gaseous exchange.
Cork- In adult stems and roots, this is the exterior protective tissue that replaces the epidermal cells. Cork cells are devoid of intercellular spaces and are dead. Suberin coagulates their cell walls, making them impermeable to gas and water molecules.
