ADVERTISEMENTS: The below mentioned article provides a study on the sclereids and sclerenchyma in plant cell with diagram. Ground tissue cells include parenchyma, (photosynthesis in the leaves, and storage in the roots), collenchyma (shoot support in areas of active growth), and schlerenchyma (shoot support in areas where growth has ceased). This is a spongy tissue also known as a mesenchymal tissue, in which several types of cells are lodged in their extracellular matrices. Phloem, on the other hand, is the living, permanent tissue that carries food and other organic nutrients from leaves to all other parts of the plant.
