Multicellularity allows for specialization of cells, leading to more efficient function and greater complexity. It also provides increased strength and protection against environmental stresses. Additionally, multicellularity allows for larger body sizes and the ability to perform more complex behaviors.
An organism being "uncellular" means that it is not composed of cells like typical living organisms, such as bacteria, plants, or animals. Instead, it may exist as a single structure or in a non-cellular form. An example of an uncellular organism is a virus.
Not all cells in a multicellular organism are constantly being replaced. While some cells, like skin cells or blood cells, have short lifespans and are regularly replaced, other cells, like neurons, have a longer lifespan and may not be replaced as frequently. Additionally, some cells, like muscle cells, can repair and regenerate themselves without being completely replaced.

No. An organism made of many cells would be a multicellular organism.
No, unicellular organisms do not have specialized cells. Instead, the entire organism carries out all functions needed for survival. Each cell in a unicellular organism is responsible for carrying out all functions necessary for life, such as metabolism, reproduction, and response to stimuli.
No. This is why you have different types of cells.
Anton von Leewenhook discovered cells, those ones specifically being cork cells.

The cells of an organism carry out the functions it needs to live. Healthier cells carry out the functions more efficiently making it easier for the organism to live aka making the organism healthier
A virus is a small infectious agent that can only replicate inside the living cells of an organism. A host is an organism that provides nourishment and a habitat for another organism. A parasite is an organism that lives on or inside another organism (the host) and benefits at the host's expense.
Different cells in a multicellular organism have specialized functions that help the organism to survive and function efficiently. Each type of cell is uniquely adapted to perform specific tasks, such as nerve cells for signaling, muscle cells for movement, and blood cells for transporting oxygen. This division of labor allows the organism to carry out complex functions necessary for its overall health and well-being.
Cells are the basic structural and functional unit of an organism.

Any tissue of a living organism containing cells that are being replaced when they die.
No. An organism made of many cells would be a multicellular organism.
