Tissue, noun, refers to a group or collection of cells that work together to perform a specific function within an organism. It is an essential building block of living creatures, forming the foundation for various organs and body structures. Tissues can be found in plants, animals, and humans, with each having a distinct composition and purpose.
In animals and humans, there are four primary types of tissues: epithelial, connective, muscle, and nervous tissue. Epithelial tissue covers the external surfaces of the body, lines internal organs, and forms glands. Connective tissue primarily supports and connects various body parts, such as bones, tendons, and blood vessels. Muscles tissues are responsible for body movement by contracting and relaxing, while nervous tissue coordinates and transmits signals throughout the body.
In plants, tissues are classified mainly into three types: dermal, ground, and vascular tissues. Dermal tissues cover and protect the outer surfaces of the plant, ground tissues perform various metabolic functions such as photosynthesis, storage, and support, and vascular tissues transport water, minerals, and nutrients throughout the plant.
Overall, tissues are integral components of an organism's structure and function, enabling proper coordination and specialization of cells to carry out specific tasks. By working collectively, different tissue types contribute to the overall health, growth, and survival of an organism, ensuring its proper functioning.
A collection of cells or derivatives of cells, forming a definite structure.

The word "tissue" has an interesting etymology. The term originated from the Latin word "tessera", which referred to a small square stone or tile used in mosaics. In Medieval Latin, "tessera" was used to describe a piece of paper or a document that was rolled up and sealed with wax.
Over time, the meaning of "tessera" evolved, and by the 14th century, it started being used in English to refer to a thin, woven fabric. This sense of the word was influenced by the French word "tissu", which meant woven fabric or cloth.
In the medical context, the word "tissue" began to be used in the early 17th century to describe the woven structure of animal or plant cells. This usage was borrowed from the general sense of fabric or woven material.
