Answers
Explanation:
Parenchyma forms the "filler" tissue in the soft parts of plants, and is usually present in cortex, pericycle, pith, and medullary rays in primary stem and root. 2)Collenchyma cells have thin primary walls with some areas of secondary thickening.
3) Sclerenchyma provides the main structural support to a plant.
Parenchyma - it is made of thin-waled cells found in the no-woody parts of plant. The cells have large spaces between them. They are involved in photosynthesis and the storage of food. The Palisades cells of leaves that contains chlorophyll, the pulp in fruits and the cotyledon in seeds are all made of parenchyma cells.
Collenchyma - it consist of long cells with thick walls and thickest edges and and is found in soft growing tissue. They give support toto the plant. They provide flexibility to some parts of the plant. They are found in shoot and leaves.
Sclerenchyma - it consist of cells that are dead and thus do not contains any protoplasm. The cells are long and narrow, thick walls. Thier is no space between them. They form column like structure that give support to the plant. They are found in hard woody stems and veins in mature leave.
