Anatomy and Physiology II Practice Test

What is the name of the process by which tissues develop into organs?

1. Histogenesis

2. Orgogenesis

3. Cell differentiation

4. Embryogenesis

The correct answer is: Orgogenesis

The correct answer, orgogenesis, refers specifically to the process in which tissues develop into organs during the formation of an organism. This stage is critical in embryonic development, where various cell types that have already undergone differentiation come together to form structures and organs that will perform specific biological functions. Orgogenesis occurs after the initial stages of differentiation, where cells take on specific roles and characteristics. Throughout this process, cells organize themselves into layers and structures that will evolve into functional organs. This organized progression is essential for proper development in the embryo, leading to a fully functional organism. The other options relate to different aspects of biological development. Histogenesis refers to the formation of tissue from cells, while cell differentiation indicates the process by which a less specialized cell becomes a more specialized cell type. Embryogenesis is the overarching term for the entire development process from fertilization to the formation of a complete organism, encompassing both histogenesis and orgogenesis within it. Understanding these distinctions helps in grasping how complex biological systems are formed through coordinated cellular activities.
