Answer Details

An organism that operates at the cellular level of organization carries out its physiological activities by using its organelles. Cells are the basic unit of life, and each cell has organelles that perform specific functions to keep the cell alive and functioning properly. These organelles include the nucleus, mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes, among others. For example, the nucleus contains the cell's genetic material and controls the cell's activities by regulating the expression of genes. Mitochondria are responsible for producing energy in the form of ATP through cellular respiration. Ribosomes are responsible for synthesizing proteins. Endoplasmic reticulum and Golgi apparatus work together to synthesize and transport proteins and lipids. Lysosomes and peroxisomes are involved in the breakdown of cellular waste and toxins. Therefore, an organism that operates at the cellular level of organization relies on its organelles to carry out its physiological activities. These organelles work together in a coordinated manner to ensure the survival and functioning of the cell.
