Detailed explanation-1: -Tissues are groups of similar cells that are specialised to perform specific functions.

Detailed explanation-2: -Specialized cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate to form a tissue, such as a muscle. Different tissues are in turn grouped together to form larger functional units, called organs.

Detailed explanation-3: -This means that they’re designed differently so that they can perform different functions. For example, your muscle cells have a very different function than your nerve cells, just like your heart cells are different from your liver cells for the same reason.

Detailed explanation-4: -Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.
