Question

differentiate between parenchyma collenchyma and sclerenchyma on the basis of their cell wall

Answer 1

Hey dear friend,

Parenchyma=>The cells of this tissue are isodiametric and spherical. Intercellular spaces are found and the cell wall is thin and made of cellulose.

Sclerenchyma =>The cells of this tissue are long ,elongated, narrow and tapering ends. Due to excessive deposition of lignin , the cell wall become very thick.

Collenchyma=>The cells are spherical,oval or polygonal in shape. The cell walls are thick at the corners facing the Intercellular sites due to deposition of cellulose and pectin.

this is perfect correct answer.
