Detailed explanation-2: -Therefore, we can conclude that the order of these structures, from smallest to largest, is cells → tissues → organs → organ systems. An organism is one living thing. An organism may be made of one cell, in which case they are referred to as a unicellular organism.

Detailed explanation-3: -A cell is the smallest independently functioning unit of a living organism.

Detailed explanation-4: -Life processes of the human body are maintained at several levels of structural organization. These include the chemical, cellular, tissue, organ, organ system, and the organism level.

Detailed explanation-5: -Cells are the most basic unit of life at the smallest level of organization. Cells can be prokaryotic (without nucleus) or eukaroyotic (with nucleus). The four categories of tissues are connective, muscles, epithelial, and nervous tissues. Organs are made of different types of tissues and perform complex functions.
