Final answer:
Small structures inside cells that perform specific functions are called organelles. They have specific roles to perform for proper functioning of the cell.
Step-by-step explanation:
Small structures inside cells that perform specific functions are called organelles. These are essentially the organs of the cell, each with a specific role to perform to ensure the cell functions properly. Examples of organelles include the nucleus which controls the cell's genetic material and metabolism, the mitochondria (the 'powerhouse' of the cell) which produce energy in the form of ATP, plastids that are involved in synthesis and storage of food, and lipids which form part of the cell membrane but are not considered organelles.
