Epithelial tissue is characterized by closely packed cells with minimal extracellular matrix, forming continuous sheets that cover body surfaces and line cavities and organs. It exhibits polarity, with distinct apical and basal surfaces, and is anchored to underlying connective tissue by a basement membrane. Epithelial tissue functions primarily in protection, absorption, secretion, and sensation, playing a crucial role in processes such as filtration and gas exchange. Additionally, it is avascular, relying on diffusion from nearby blood vessels for nutrient and waste exchange.

What is tessue culture?
Tissue culture is a technique used in biology to grow cells, tissues, or organs in a controlled environment outside of their natural habitat, typically in a nutrient-rich culture medium. This method allows for the propagation of plants, the study of cellular processes, and the development of medical treatments, such as regenerative medicine. By isolating and cultivating specific cells, researchers can study their behavior and characteristics in detail. Tissue culture is widely used in agriculture, horticulture, and biotechnology for plant breeding and conservation.
