Levels Of Organization 7th Grade Science - Quiz

Explore the structural hierarchy in biological organisms with this engaging 7th-grade science quiz. Questions cover the progression from cells to tissues, organs, and organ systems, highlighting key biological concepts and structures.

Questions and Answers

1.

A group of organs working together to perform a specific function is know as a/an:
- A.
  
  Cell
- B.
  
  Tissue
- C.
  
  Organ
- D.
  
  Organ System
Correct Answer
D. Organ System

Explanation
An organ system is a group of organs that work together to perform a specific function. Each organ within the system has a specific role, and they collaborate to carry out a particular task or process in the body. For example, the respiratory system includes organs such as the lungs, trachea, and bronchi, which work together to facilitate the exchange of gases. Therefore, an organ system best describes a group of organs working together to perform a specific function.

2.

Cells that are similar in structure and function join together to form
- A.
  
  Cells
- B.
  
  Tissue
- C.
  
  Organ
- D.
  
  Organ Systen
Correct Answer
B. Tissue

Explanation
Cells that are similar in structure and function join together to form tissue. Tissues are groups of cells that work together to perform a specific function in the body. They can be categorized into four main types: epithelial, connective, muscle, and nervous tissue. Epithelial tissue covers and protects body surfaces, connective tissue provides support and structure, muscle tissue allows for movement, and nervous tissue transmits and processes information. By joining together, cells form tissues that enable specialized functions and contribute to the overall functioning of organs and organ systems.

Cells, tissue, and organs work together to form a/an
- A.
  
  Cells
- B.
  
  Tissue
- C.
  
  Organ
- D.
  
  Organ System
Correct Answer
D. Organ System

Explanation
Cells, tissues, and organs work together to form an organ system. An organ system is a group of organs that work together to perform a specific function in the body. Each organ within the system has a specific role, and they collaborate to maintain homeostasis and carry out vital processes. Examples of organ systems include the respiratory system, circulatory system, and digestive system. Therefore, the correct answer is Organ System.

The basic unit of structure and function in all living things:
- A.
  
  Cells
- B.
  
  Tissue
- C.
  
  Organ
- D.
  
  Organ System
Correct Answer
A. Cells

Explanation
Cells are the basic unit of structure and function in all living things. They are the smallest building blocks of life and are responsible for carrying out all the essential processes necessary for an organism's survival. Cells can exist as single-celled organisms or work together to form tissues, organs, and organ systems. They are responsible for carrying out functions such as reproduction, metabolism, and response to stimuli. Without cells, living organisms would not be able to carry out the complex processes required for life.

The brain, kidneys and lungs are all examples of:
- A.
  
  Cells
- B.
  
  Tissue
- C.
  
  Organs
- D.
  
  Organ System
Correct Answer
C. Organs

Explanation
The brain, kidneys, and lungs are all examples of organs. Organs are composed of different types of tissues that work together to perform specific functions in the body. Each organ has a unique structure and function, and they are part of larger organ systems that work together to maintain homeostasis and carry out essential bodily functions.

Rate this question:
6.

Cells that are ______________________ in structure and fuction join together to form tissues.

Correct Answer
similar, the same

Explanation
Cells that are similar in structure and function join together to form tissues. This means that the cells have comparable characteristics and perform similar tasks. When cells with similar properties come together, they can collaborate and work in harmony to carry out specific functions within the body. This organization at the cellular level allows for the efficient functioning of tissues and ultimately contributes to the overall functioning of organs and systems in the body.

7.

Tissues are the __________ (number) level of organization.

Correct Answer
2nd, 2, two, second

Explanation
Tissues are the second level of organization in living organisms. This means that after cells, tissues are formed by a group of similar cells working together to perform a specific function. This organization allows for more complex structures and functions to develop in multicellular organisms.

1
8.

In the levels of organization in an organism, a group of similar cells working together is called a __________.

Correct Answer
tissue, Tissue

Explanation
In biology, the levels of organization are structured hierarchically, starting from the simplest building blocks to the most complex living entities. A tissue is a group of similar cells that perform a specific function. For example, muscle tissue is composed of muscle cells that contract to produce movement, while nervous tissue is made up of neurons that transmit signals throughout the body. Tissues then combine to form organs, which further group into organ systems, ultimately creating a complete organism.

9.

Cells are what level of organization

Correct Answer
1st , first, 1, 3, third, 3rd

Explanation
The given correct answer is "1st, first, 1, 3, third, 3rd". This answer suggests that cells are the first level of organization. This is because cells are the basic structural and functional units of all living organisms. They are the building blocks of tissues, organs, and ultimately, entire organisms. Therefore, cells can be considered as the foundational level of organization in biological systems.

10.

Digestive system, respiratory system and integumentary system are examples of:

Correct Answer
organ systems, organ system

Explanation
The digestive system, respiratory system, and integumentary system are examples of organ systems. An organ system is a group of organs that work together to perform a specific function in the body. Each system has its own set of organs that contribute to the overall function of the system. Therefore, the correct answer is organ systems, referring to the multiple systems in the body, and organ system, referring to each individual system.
