Which level of organization comes immediately after the cellular level?

The correct answer, which is tissue, follows the cellular level in the hierarchy of biological organization. At the cellular level, the basic structural and functional unit of life is recognized. Cells aggregate and work together to form tissues, which are groups of similar cells that perform a specific function within an organism.

Tissues serve as the next step in complexity, organizing cells into functional units that carry out specialized tasks. For example, muscle tissue allows for movement, while nervous tissue is involved in transmitting signals throughout the body.

The other options represent levels of organization that are further along the hierarchy. Organismal pertains to the entire living individual composed of various systems and tissues working together. System refers to a group of organs that work collaboratively to perform complex functions, while chemical refers to the most basic level involving atoms and molecules that constitute the cellular structures. Thus, all these options denote levels that come after or represent a different aspect of biological organization compared to tissue.
