Cellular organelles are specialized structures within cells that perform distinct functions necessary for the cell's survival and operation. Examples of organelles include the nucleus, which houses genetic material, and mitochondria, known as the powerhouse of the cell for energy production. Other organelles, like ribosomes, are involved in protein synthesis, while endoplasmic reticulum helps in the production and transport of proteins and lipids. Each organelle plays a crucial role in maintaining cellular health and efficiency. The Golgi apparatus modifies and packages proteins, while lysosomes contain enzymes for digestion and waste removal. Together, these organelles work in harmony to support the life processes of the cell.
