What are groups of similar cells called?

Rationale

Tissue

Tissues are groups of similar cells that work together to perform a specific function in the body. They are fundamental biological units that combine to form organs and systems, playing a crucial role in the organization of multicellular organisms.

A (Membrane) YOUR ANSWER

Membranes are not groups of cells but rather structures that serve as barriers or interfaces in biological systems. They are composed of lipid bilayers and proteins, and while they may contain cells, they do not represent an organization of similar cells working together for a common function.

B (System) YOUR ANSWER

A system is a higher level of biological organization that includes multiple organs working together to perform complex functions. While systems may involve various tissues, they do not refer to groups of similar cells, making this option incorrect for the question posed.

C (Organ) YOUR ANSWER

Organs are structures made up of different types of tissues that work together to perform specific tasks. While organs are composed of tissues, they represent a more complex level of organization than simply groups of similar cells, which is the focus of the question.

D (Tissue) CORRECT

Tissues are indeed the correct answer, as they are defined specifically as groups of similar cells that collaborate to execute particular functions, such as muscle tissue contracting or nervous tissue transmitting signals.

Conclusion

In biological terminology, tissues are essential units comprising similar cells that perform unified roles, contrasting with membranes, systems, and organs, which represent different levels of complexity. Understanding this distinction is vital in fields like anatomy and physiology, where knowledge of tissue types informs how various body functions are carried out.
