Detailed explanation-1: -Solution : Meristematic cells, parenchymatous cells, cells of leaves and fruits.

Detailed explanation-2: -Thus, the primary cell wall is found in between the middle lamella and the secondary cell wall of the plant cell wall.

Detailed explanation-3: -COLLENCHYMA: A PRIMARY OR SECONDARY CELL WALL? Collenchyma cell walls are generally described as being primary walls which they resemble in properties and composition.

Detailed explanation-4: -Collenchyma is a simple plant tissue, consisting of only one cell type. Collenchyma cells are elongated, living cells that occur especially in peripheral positions in leaves and stems of eudicotyledons where they provide mechanical support while they are still growing [1, 2, 3].

Detailed explanation-5: -Collenchyma is not a primary tissue because it only develops from meristematic cells, for example, cambium and procambium. Collenchyma is usually found between the cortex of the stem and the endoderm of its vascular bundles.
