Parenchyma is a type of plant tissue that plays a crucial role in various functions, including photosynthesis, storage, and tissue repair. It consists of living cells that are typically thin-walled and can vary in shape. This tissue is found in many parts of the plant, such as leaves, stems, and roots, making it essential for overall plant health. In addition to its structural role, parenchyma cells can also store nutrients and water, helping the plant survive in different environments. These cells are versatile and can adapt to different functions depending on the plant's needs, contributing to its growth and development.
