There are five main types of plant tissues: parenchyma, collenchyma, sclerenchyma, xylem, and phloem. Parenchyma is made of thin-walled cells that perform photosynthesis and store food. Collenchyma provides flexibility and support to plant structures. Sclerenchyma is made of thickened, non-living cells that provide strength and support. Xylem and phloem make up the vascular tissue and transport water, minerals, and food throughout the plant.
