Animal tissues can be grouped into four basic types: connective, muscle, nervous, and epithelial. Multiple tissue types comprise organs and body structures. While all animals can generally be considered to contain the four tissue types, the manifestation of these tissues can differ depending on the type of organism. For example, the origin of the cells comprising a particular tissue type may differ developmentally for different classifications of animals. The epithelium in all animals is derived from the ectoderm and endoderm with a small contribution from themesoderm which forms the endothelium.
Generally, cells differentiate into different tissues depending on the tissues surrounding them.
Different types of tissues working together to perform a function make up an organ. cell-> tissue -> organ -> organ system -> organism
Cells are the smallest unit of life. Large groups of cells with the same purpose are called tissue, groups of tissue with the same purpose form organs, organs with similar purposes form systems and systems form organisms.
Groups of cells working together form tissues, groups of tissues working together form organs, organs working together form organ systems, organ systems cooperating and working together form organisms.

The organization levels of multicellular organisms are cells, tissues, organs, and organ systems. Cells are the basic unit of life, tissues are groups of cells with similar functions, organs are structures composed of different tissues working together, and organ systems are groups of organs that work together to perform specific functions in the organism.
Organs are structures in the body that perform specific functions. They are made up of different types of tissues that work together to carry out these functions. Tissues are groups of cells that are similar in structure and function. In an organ, different types of tissues come together to form a specialized structure that performs a specific task.
Cells are the building blocks that make up all living organisms. Tissues are groups of like cells that, together, perform a function for the living organism. Organs are relatively independent groups of tissues (tissue or tissues) that work together to perform a function for the living organism

Cells are the basic building blocks of tissues. Tissues are groups of similar cells working together to perform a specific function. Organs are made up of different types of tissues working together. Organ systems are groups of organs working together to perform complex functions within the body.
Groups of cells that work together are called tissues.
