Cell specialization.
yes it does
more specialized to do different jobs.
no
Different cells in an organism have different jobs and functions to do. With all of them functioning properly, they can work together to perform more complex jobs like sustaining life. Cells that are similar to each other and do the same job are grouped together to form tissues. Muscle cells make muscle, nerve cells make nerve tissues and so on.

Unicellular organisms do NOT have specialized cells. By definition.

They do different jobs.
Cellular Differentiation
Multicellular organisms carry out functions through the division of labor among specialized cells and tissues. Different cells perform specific roles in processes such as respiration, digestion, and movement. Coordination and communication between cells are essential for the overall functioning of the organism.
Cells differ because they have different functions. Nerve cells have to do nerve jobs while muscle cells have to do muscle jobs and so on. This means cells vary in shape, size etc. Some may contain more mitochondria, for example, then otehr cells. Each type of cell contains different genetic materials.
Plant and animal cells have different organelles because they have evolved to meet the specific needs of each type of organism. Plant cells have chloroplasts for photosynthesis and a cell wall for structure, which are not present in animal cells. Animal cells have lysosomes for digestion and centrioles for cell division, which are not typically found in plant cells.
