Open in App
Solution
The correct option is B Cucurbita
Collenchyma cells contain protoplasm and are living without intercellular spaces. These are chiefly found in the hypodermis of dicot herbaceous plants like Cucurbita.These are divided into four types on the basis deposition and intercellular space:
(A)Angular - Thickening of cells is confined to the corners of the cell.
(B)Plate - When the thickenings are present on the tangential wall.
Ex-sunflower
(C)Lacunar-If the thickened cell is associated with the intercellular spaces of the adjacent side.Ex-Cucurbita,Salvia
(D)Annular -These are uniformly thickened throughout the wall.
So the correct option is 'Cucurbita'.
