Plant Tissues and Meristems

The types of simple tissues are parenchyma, collenchyma, sclerenchyma, and aerenchyma. Parenchyma tissue functions in photosynthesis, storage, and secretion. Collenchyma tissue provides mechanical support to the growing plant. Sclerenchyma tissue provides rigidity and strength to the plant. Aerenchyma tissue facilitates gaseous exchange in aquatic plants.

Apical meristem is characterized by active cell division and elongation. It is found at the tip of the root or shoot of the plant, responsible for primary growth and the formation of new tissues.

Tissues in plants work together by coordinating their functions to carry out specific tasks. For example, parenchyma tissue in leaves performs photosynthesis, while xylem and phloem tissues transport water, nutrients, and sugars throughout the plant.
