Verified step by step guidance

Understand the hierarchy of biological organization: The levels of organization in biology typically follow this order: cells, tissues, organs, organ systems, and organisms.

Identify the smallest unit of life: Cells are recognized as the smallest unit of life, capable of performing all life processes.

Recognize how cells form tissues: Cells of similar structure and function group together to form tissues.

Clarify the composition of organs: Organs are made up of different types of tissues working together to perform specific functions.

Understand the role of organ systems: Organ systems consist of different organs that work together to perform complex functions necessary for the survival of an organism.
