Plant tissue is composed of two main types: XYLEM and parenchyma. XYLEM is a type of tissue that transports water and minerals from the roots to the leaves of a plant. It is composed of dead cells that form a network of tubes throughout the plant. Parenchyma is a type of living tissue that is found in all parts of a plant. It is responsible for photosynthesis, storage of food, and other metabolic activities. Together, these two types of tissue are essential for the growth and development of a plant.
