Test: Level of Organization - JAMB MCQ

The level of organization in living organisms progresses from cells to tissues, organs, and finally, organ systems. Organ systems consist of multiple organs working together to perform specific functions, representing the highest level of complexity in living organisms.

Tissues are formed by a group of similar cells that work together to perform a specific function. Different types of tissues include epithelial, connective, muscular, and nervous tissues. Tissues are the next level of organization above cells.

Organs are formed by the integration of different tissues that work together to carry out specific functions. Examples of organs include the heart, lungs, liver, and brain. Organs are the next level of organization above tissues.

Organ systems involve the integration of different organs that work together to perform specific functions necessary for the survival of the organism. Examples of organ systems include the respiratory system, circulatory system, and nervous system. Organ systems are the highest level of organization in living organisms.

Cells are the smallest and most basic unit of life. They are capable of carrying out essential functions necessary for the survival and functioning of living organisms. Cells are the building blocks of tissues, organs, and organ systems.

Organ systems, such as the nervous system and endocrine system, are responsible for the coordination and control of body functions. These systems integrate and communicate with different organs and tissues to maintain homeostasis and regulate various physiological processes.

The respiratory system, which is an organ system, is responsible for gas exchange and oxygen transport in the body. It involves the integration of organs such as the lungs, bronchi, and trachea to ensure the exchange of gases (oxygen and carbon dioxide) between the body and the environment.

Tissues are groups of cells with similar structure and function that work together to perform specific functions in an organism. Examples of tissues include epithelial tissue, connective tissue, muscle tissue, and nervous tissue.

Organ systems are composed of different organs that work together to carry out a specific function in the body. Examples of organ systems include the digestive system, respiratory system, circulatory system, and nervous system.

Cells are the basic structural and functional units of life. They are the smallest level of organization that can carry out all the essential functions necessary for life. Cells may exist as single-celled organisms or as part of multicellular organisms.
