Plants have two types of tissues: meristematic and permanent. Meristematic tissue consists of actively dividing cells found in root and shoot tips, responsible for growth. Permanent tissue forms from meristematic tissue. It is divided into simple and complex tissues. Simple tissue includes parenchyma, which stores food and performs photosynthesis, collenchyma, which provides flexibility and support, and sclerenchyma, which gives strength. Complex tissue includes xylem, which transports water and minerals, and phloem, which transports food.
