Detailed explanation-1: -Parenchyma cells are responsible for storage of food and water. These cells are living and vacuolated protoplasm. The parenchyma cells of epidermis have cuticles in their walls.

Detailed explanation-2: -The main tissue types of the ground tissue system are parenchyma, collenchyma and sclerenchyma. Parenchyma have thin walls of cellulose, whereas collenchyma have cell walls with thickened areas of additional cellulose. Sclerenchyma cells have lignified cell walls.

Detailed explanation-3: -Ground tissue is all the other tissue in a plant that isn’t dermal tissue or vascular tissue. 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).

Detailed explanation-4: -Ground tissue comprises the majority of a young plant and lies between the vascular and dermal tissues. The major cells of the ground tissue are parenchyma cells, which function in photosynthesis and nutrient storage.

Detailed explanation-5: -Ground tissue makes up much of the interior of a plant and carries out basic metabolic functions. Ground tissue in stems provides support and may store food or water. Ground tissues in roots may also store food.
