Do you know about the levels of the cellular organization of an animal's body? Try out these levels of organization quiz questions and answers and evaluate yourself. The body is made up of different systems that ensure it can perform at its best. These said systems are made up of organs, and they each have a specific function in the body. How much do you know about the organization of the human body and how the organs operate? Take up the test below and get to find out!

Questions and Answers

1.

The 1st level of organization is......
- A.
  
  The cell
- B.
  
  Tissues
- C.
  
  Organs
- D.
  
  Populations
Correct Answer
A. The cell

Explanation
The 1st level of organization refers to the basic structural and functional unit of all living organisms, which is the cell. Cells are the building blocks of life and are responsible for carrying out various functions necessary for an organism's survival. They can work independently or together to form tissues, organs, and ultimately, entire organisms. Therefore, the correct answer is the cell.

Cardiac muscle, cardiac tissue, and the heart are grouped in what system?
- A.
  
  Circulatory
- B.
  
  Respiratory
- C.
  
  Digestive
- D.
  
  Nervous
Correct Answer
A. Circulatory

Explanation
Cardiac muscle, cardiac tissue, and the heart are all part of the circulatory system. The circulatory system is responsible for transporting blood, nutrients, and oxygen throughout the body. The heart, which is made up of cardiac muscle and tissue, pumps the blood and helps maintain the flow of blood through the blood vessels. Therefore, it is logical to group cardiac muscle, cardiac tissue, and the heart in the circulatory system.

What term describes adaptation of cells for a specific job?
- A.
  
  Multicellular
- B.
  
  Structure
- C.
  
  Level of organization
- D.
  
  Specialization
Correct Answer
D. Specialization

Explanation
Specialization is the term that describes the adaptation of cells for a specific job. In multicellular organisms, different cells have specific functions and characteristics that allow them to perform specific tasks. This specialization enables cells to work together efficiently and effectively, contributing to the overall functioning of the organism.

The brain and spinal cord work together to do a specific job. This is an example of?
- A.
  
  Organ system
- B.
  
  Cell
- C.
  
  Tissue
- D.
  
  Muscle
Correct Answer
A. Organ system

Explanation
The brain and spinal cord work together to perform various functions, such as transmitting signals, coordinating movement, and processing information. They form the central nervous system, which is responsible for controlling and coordinating the activities of the body. An organ system is a group of organs that work together to perform a specific function, and in this case, the brain and spinal cord function as a unit to carry out their specific job. Therefore, the correct answer is organ system.

Which is the correct order for the five levels of organization in the human body, from most to least complex?
- A.
  
  Cell, tissue, organ, organ system, organism
- B.
  
  Organism, organ system, organ, tissue, cell
- C.
  
  Organism, organ, organ system, tissue, cell
- D.
  
  Organism, cell, tissue, organ, organ system
Correct Answer
B. Organism, organ system, organ, tissue, cell

Explanation
The correct order for the five levels of organization in the human body, from most to least complex, is organism, organ system, organ, tissue, cell. This order starts with the highest level of organization, which is the organism, representing the entire individual. The next level is the organ system, which consists of multiple organs working together to perform a specific function. Organs are the next level, which are composed of different tissues and have specific functions. Tissues are then formed by groups of similar cells working together. Finally, the cell is the smallest and most basic unit of life.

What level of organization would describe an animal's eye?
- A.
  
  Cell
- B.
  
  Tissue
- C.
  
  Organ
- D.
  
  Organ system
Correct Answer
C. Organ

Explanation
An animal's eye is an example of an organ. Organs are composed of different types of tissues that work together to perform specific functions. In the case of the eye, it is made up of various tissues such as the cornea, iris, lens, and retina, which work together to enable vision. Organs are a higher level of organization compared to cells and tissues, as they are composed of multiple tissues working together. Organ systems, on the other hand, are a higher level of organization that consists of multiple organs working together to carry out specific functions in the body.

Cells make up
- A.
  
  Organs
- B.
  
  Organ Systems
- C.
  
  Tissues
- D.
  
  Organisms
Correct Answer
C. Tissues

Explanation
Cells are the basic building blocks of living organisms. They come together to form tissues, which are groups of cells that work together to perform a specific function. Tissues then combine to form organs, which are structures made up of different types of tissues that work together to carry out specific functions in the body. These organs further integrate to form organ systems, which are groups of organs that work together to perform complex functions and maintain homeostasis in the organism. Therefore, the correct order is cells, tissues, organs, and organ systems, with organisms being the highest level of organization made up of all these components.

Organ Systems make up....
- A.
  
  Tissues
- B.
  
  Cells
- C.
  
  Organisms
- D.
  
  Populations
Correct Answer
C. Organisms

Explanation
Organ systems make up organisms. An organism is a living entity that consists of multiple organ systems working together to perform various functions necessary for life. These organ systems include the respiratory system, circulatory system, digestive system, and many others. Each system is made up of different organs, which are composed of tissues, which in turn are made up of cells. Therefore, the correct answer is organisms.

The highest level of organization is
- A.
  
  Organs
- B.
  
  Organisms
- C.
  
  Cells
- D.
  
  Populations
Correct Answer
D. Populations

Explanation
In biological organization, populations represent the highest level of organization among the options given. A population consists of individuals of the same species living and interacting in a specific area. This level is higher than cells, organs, and organisms, as it encompasses multiple organisms and considers their interactions, genetic diversity, and dynamics within an ecosystem, reflecting broader ecological and evolutionary processes.

The tissue level of organization comes.....
- A.
  
  After cells
- B.
  
  After organs
- C.
  
  After cells before organs
- D.
  
  A and b
- E.
  
  This is not an organizational level
Correct Answer
C. After cells before organs

Explanation
The tissue level of organization comes after cells and before organs. This means that cells are the building blocks of tissues, and tissues are groups of similar cells that work together to perform a specific function. Tissues then come together to form organs, which have a more complex structure and perform more specialized functions. Therefore, the correct answer is that the tissue level of organization comes after cells and before organs.
