Tissue renewal

In multicellular organisms, tissue is a level of structure that consists of a group of physically and functionally identical cells and their intercellular substances. Unicellular organisms do not have tissues. Tissues are absent or poorly differentiated even in the simplest multicellular animals, such as sponges. However, more evolved multicellular animals and plants have specialized tissues that may organize and govern an organism's reaction to its surroundings. The word tissue is derived from the Latin word 'weave.' Plants and animals have various kinds of tissue systems that differ in their work and composition according to the different requirements.
