Simple Permanent Tissue: They are divided into three types based on their function: sclerenchyma, collenchyma, and parenchyma.
Phloem and xylem are examples of complex permanent tissue.
Parenchyma is made up of living polygonal cells with a large central vacuole and intercellular gaps. Ground tissue and pith are created by parenchymatous cells.
Collenchyma are live cells that are spread out with minute intercellular gaps. Pectin and cellulose make up their cell walls.
Sclerenchyma is a type of dead cell that has lignin deposits in its cell wall. There are no gaps between the cells. Sclerenchyma can be seen on the outside of seeds and nuts, as well as around vascular tissues in stems and leaf veins.
The transfer of dissolved chemicals and water throughout the plant is aided by xylem. Vessels, tracheids, xylem fibres, and xylem parenchyma are some of the xylem’s many components. Lignin is found in Xylem fibres and Tracheids, and it gives structural support to the plant.
Food is transported throughout the plant thanks to phloem tissue. Phloem fibres, sieve tubes, phloem parenchyma, and companion cells are some of the many components of phloem.
Final Answer:
The following are two simple and two sophisticated permanent tissues found in plants:
Parenchyma, collenchyma, and sclerenchyma are simple tissues.
Phloem and Xylem are two complex tissues.
