what are the functions of parenchyma collenchyma and sclerenchyma
Ground tissue
The ground tissue of plants includes all tissues that are neither dermal nor vascular . It can be divided into three classes based on the nature of the cell walls . Parenchyma cells have thin primary walls and usually remain alive after they become mature . Parenchyma forms the `` filler '' tissue in the soft parts of plants. usually present in cortex , pericycle , pith , and medullary rays in primary stem and root . Collenchyma cells have thin primary walls with some areas of secondary thickening . Collenchyma provides extra structural support , particularly in regions of new growth . Sclerenchyma cells have thick lignified secondary walls and often die when mature . Sclerenchyma provides the main structural support to a plant .
