Cell membrane the thin layer of protein and fat that surrounds the cell but is inside the cell wall. Ground tissue carries out different functions based on the cell type and location in the plant and includes 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 is the site of photosynthesis provides a supporting matrix for the vascular tissue provides structural support for the stem and helps to store water and sugars.
