Detailed explanation-1: -Is the statement true or false? Because they share similar structures, cells all carry the same function. False.

Detailed explanation-2: -Cells of various types have different functions because cell structure and function are closely related. It is apparent that a cell that is very thin is not well suited for a protective function. Bone cells do not have an appropriate structure for nerve impulse conduction.

Detailed explanation-3: -A group of cells of similar origin that are structurally similar and perform a particular function are called tissue e.g., nervous tissues, blood, etc.

Detailed explanation-4: -Tissue is a group of cells that have similar structure and that function together as a unit. Primary types of body tissues include epithelial, connective, muscular, and nervous tissues. Epithelial tissues form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.

Detailed explanation-5: -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.
