A permanent plant tissue made up of living cells having thickening at the corners is ______________________.
A permanent plant tissue made up of living cells having thickening at the corners is ______________________.
The correct option is B Collenchyma
Sclerenchyma tissues are a type of permanent tissue. They are dead, long, thin narrow cells with thickened walls without any internal space.
Parenchyma is a type of permanent tissue. They are thin-walled, flexible and loosely packed cells. They are often alive at maturity. Therefore, option C is incorrect.
Phloem complex permanent tissue made of four types of cells as sieve tubes, companion cells, phloem fibers, and phloem parenchyma. It is the vascular or conductive tissues of the plant. Their key function is to transport food material from leaves to other parts of the plant. Hence, option D is incorrect.
Collenchyma cells are thin-walled with irregular thickening at the corners. They provide extra structural support and flexibility to plant. Therefore, option B is correct.
