Which term means a group of similar cells combined to perform a common function?

Rationale

Tissue

A tissue is defined as a group of similar cells that work together to perform a specific function within an organism. This classification is fundamental in biology, as it forms the basis for higher levels of organization, such as organs and systems.

A (Tissue) CORRECT

This term accurately describes a collection of similar cells that are organized to perform a particular function, such as muscle tissue facilitating movement or epithelial tissue covering surfaces. Tissues are essential components of all multicellular organisms, providing structure and function through their collective activity.

B (Organism) YOUR ANSWER

An organism refers to an individual living entity that can function independently. It encompasses all levels of biological organization, from cells to systems, but does not specifically denote a collection of similar cells. Thus, it is too broad a term to fit the definition of a group of similar cells.

C (System) YOUR ANSWER

A system is a complex organization of different tissues and organs that work together to carry out specific functions within an organism. While systems are crucial for overall biological function, they consist of multiple types of tissues rather than a single group of similar cells, making this term incorrect.

D (Organ) YOUR ANSWER

An organ is a structure composed of different types of tissues that collaborate to perform a specific function, such as the heart or lungs. Like systems, organs involve multiple tissue types, thereby excluding them from being defined as a group of similar cells.

Conclusion

In summary, the term "tissue" specifically denotes a group of similar cells that function together, distinguishing it from broader or more complex biological terms such as organism, system, and organ. Understanding this classification is essential for grasping the hierarchical organization of biological structures and functions.
