• Vascular bundle comprises of xylem and phloem. Xylem transports water and minerals from roots to other plant parts. Phloem transports food from leaves to the plant parts.
• Aerenchyma is a special type of parenchyma. Cells of aerenchyma have air cavities filled with gases. This makes them light and provides buoyancy.
• Epidermis is the outermost protective layer of the plant body. Epidermis of aerial plants contains numerous stomata. They regulate transpiration and gaseous exchange.
• Cambium helps in increasing the girth of the stem. These are meristematic cells. They are present between phloem and xylem. They produce secondary phloem towards the outside and secondary xylem towards the inner side.
