Various Types of Plant Cells

Description: Parenchyma cells are thin walled components of the ground tissue. They make up the bulk of nonwoody structures and contain the chlorophyll necessary for photosynthesis. They also form epidermal cells and are part of transport tissues.

Description: Collenchyma cells are elongated cells with underdeveloped cell walls. They offer support to the growing leaves and shoots. They pass through a short stage during differentiation from the meristem where they appear similar to parenchyma, but the cell wall development is noticeably different.

Description: Sclerenchyma cells offer structural and mechanical support. They occur in two types, stone cells and fibers. They have a secondary cell wall.

Description: The tracheary elements include the tracheids and vessel elements. They are elongated cells that transport water and are found in the xylem.
