tissue, in physiology, a level of organization in multicellular organisms; it consists of a group of structurally and functionally similar cells and their intercellular material. By definition, tissues are absent from unicellular organisms.

In biology, tissue is an assembly of similar cells and their extracellular matrix from the same embryonic origin that together carry out a specific function. [ 1 ] [ 2 ] Tissues occupy a biological organizational level between cells and a complete organ .

2017年4月28日 · The word tissue comes from a form of an old French verb meaning “to weave”. There are four different types of tissues in animals: connective, muscle, nervous, and epithelial. In plants, tissues are divided into three types: vascular, ground, and epidermal.

In simple terms, tissue can be defined as a group of cells with similar shape and function are termed as tissues. They form a cellular organizational level, intermediate between the cells and organ system.

2024年10月8日 · Types of connective tissue include loose connective tissue (provides flexibility), dense connective tissue (provides strength), adipose tissue (stores fat), blood (transports nutrients and waste), and bone (provides structure).

2022年6月16日 · What is tissue in the body? The body tissue is an aggregation of cells that function together and have a similar function. The cells of a multicellular organism do not usually function independently instead they are usually associated with other cells forming a tissue.

2023年10月30日 · There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Epithelial tissue creates protective boundaries and is involved in the diffusion of ions and molecules.

There are four broad classifications of tissue: epithelial, connection, muscle, and nervous tissue. Each tissue type also has sub-classifications.
