What is Ground Tissue? • Ground Tissue is simple non-meristematic tissue (non-dividing tissue) made up 3 cell types: paranenchyma, collenchyma and sclerenchyma.
What’s special about Ground Tissue? • Ground tissue is special because it is needed for food intake. It’s also special because it provides the leaves of a plant with mesophyll and without the plant wouldn’t be able to repair any of it’s wounds.
3 Cell Types • Parenchyma, the most abundant ground tissue, consists of thin-walled, metabolically active cells that carry out a variety of functions in the plant, including photosynthesis and storage. • Collenchyma tissue is composed of narrow, elongated cells with thick primary walls. Collenchyma cells provide structural support to the growing plant body. • Sclerenchyma consists of two types of cells, sclereids and fibers Both have thick secondary walls and are frequently dead at maturity. Sclereids occur in a variety of shapes, ranging from roughly spherical to branched, and are widely distributed throughout the plant.
What does it do? • Ground tissue is responsible for storing carbohydrates , produced by the plant, it lies between the vascular and dermal tissue. • The major cells of the ground tissue have thin walls, many chloroplasts and large vacuoles, and they form the mass leaves, stems and roots. • Many different functions are performed by ground tissue including photosynthesis, storage, and support
