In multicellular organisms, cells are often organized into tissues, organs, and organ systems.
Multicellular organisms require specialized organs and systems because in multicellular organisms, different jobs are done by different cells that are specialized, e.g. A blood cell carries oxygen. A nerve cell sends and receives signals. In multicellular organisms different functions are divided among different cells. The cells in multicellular organisms are organized in ways the enables them to survive and reproduce. For any multicellular organism to survive, different cells must work together. The right type of cell must be in the right place to do the work that need to be done.
Organisms consisting of only one a single cell are called unicellular. A bacteruim or a protist like amoebas and paramecia are unicellular. While, most of the oganisms you are familiar with, such as dogs and trees, are multicellular. Multicellular organisms may have their cells organized into tissues, organs, and systems.

From smallest to largest, a multicellular organism can be organized into cells, tissues, organ systems, and organisms.

Cells are organized into tissues in multicellular organisms. Tissues are further organized into organs. This organization allows for the localization and isolation of biological processes.
In most multicellular organisms, cells are organized by their function. Brain cells, for example, have a specific structure because of their purpose.

In unicellular organisms, all the functions to carry out life is taken place by only single cell like digestion, respiration, excreation, etc. where as in multicellular organisms different functions are carried by different organs consisting of different type of cells like Red Blood cells helps in respiration and liver cells helps in digestion and leukocytes helps in immunity so they are divided according to their function but work with coordinate to each other where as, as said earlier in unicellular organisms the single cell works independently.

The cells of multicellular organisms become specialized for particular tasks and communicate with one another to maintain homeostasis. Specialized cells in multicellular organisms are organized into groups. A tissue is a group of similar cells that performs a particular function.
