There are three types of ground tissue: collenchyma, sclerenchyma, and parenchyma. Collenchyma (Figures \(\PageIndex{3-4}\)) is living supportive tissue that has elongated cells and an unevenly thickened primary cell wall. Its main function is the mechanical support of young stems and leaves via turgor. Figure \(\PageIndex{3}\): Collenchyma ...
These three cell types are parenchyma, collenchyma, and sclerenchyma. Figure \(\PageIndex{1}\): This diagram shows the three major cell types found in plants. In the upper left, parenchyma cells have an evenly thickened primary wall (shaded with stripes in the illustration).
Parenchyma cells are found in every soft part of the plant, but collenchyma cells are found in specific part of the plant like leaves, stems, and petioles, whereas sclerenchyma cells are found in mature parts of the plants or trees.
Ground tissue – This makes up the root vascular and epidermal system majorly made up of parenchyma, collenchyma, and sclerenchyma cells responsible for plant photosynthesis, storage of water and food, and the plant support system. Plant cells multiply by cell division, a mechanism known as Mitosis, which takes place within its nucleus.
Parenchyma cells typically have a thin cell wall and large central vacuole. Collenchyma Cells: These cells provide support for the plant, particularly in regions of new growth. They have irregularly thick cell walls and are often found under the epidermis, the outermost layer of the plant.
Sclerenchyma cells lying near the vessels and tracheids, and thus part of the vascular bundle. They are strung together end to end like the vessels and tracheids, but unlike those water carriers they have no pits or perforations and instead have thick primary and secondary cell walls.

Simple permanent tissues are of three types— parenchyma, collenchyma and sclerenchyma. i. Parenchyma: (Gk. para- beside, engchyma-tissue): Parenchyma is a simple permanent living tissue which is made up of thin-walled similar isodiametric cells. It is the most abundant and common tissue of plants.
The main tissue types of the ground tissue system are parenchyma, collenchyma and sclerenchyma. Parenchyma have thin walls of cellulose, whereas collenchyma have cell walls with thickened areas of additional cellulose. Sclerenchyma cells have lignified cell walls.
Simple tissues in plants are parenchyma, collenchyma, and sclerenchyma. Compound tissues in plants are the xylem and phloem, which make up the plant’s vascular system. The xylem transports water and mineral ions, whereas the phloem transports sugars and amino acids.
