Organ and Organ System Quiz
Every multicellular animal, from a simple Hydra to a human being, solves the problem of survival through division of labour. Cells group into tissues, tissues build organs, and organs associate into organ systems.
This quiz tests your grasp of that hierarchy:
- The precise definition of a tissue
- The four basic tissue types of complex animals
- How tissues form organs such as the stomach, lung, heart and kidney
- How organs combine into organ systems like the digestive and respiratory systems
- The meaning of morphology and anatomy
Read each question carefully and choose the single best option. Good luck!
Q1. In multicellular animals, a group of similar cells along with intercellular substances performing a specific function is called:
The lesson defines a tissue as a group of similar cells along with intercellular substances performing a specific function.
Q2. How many basic types of tissues are found in all complex animals?
The lesson states that all complex animals consist of only four basic types of tissues.
Q3. Which of the following is NOT listed in the lesson as an example of an organ?
The digestive system is given as an example of an organ system, not an organ. Stomach, lung, heart and kidney are organs.
Q4. When two or more organs perform a common function by their physical and/or chemical interaction, they together form:
The lesson defines an organ system as two or more organs performing a common function through physical and/or chemical interaction.
Q5. Which of the following is given in the lesson as an example of an organ system?
The respiratory system is cited as an example of an organ system, along with the digestive system. Heart, kidney and stomach are organs.
Q6. The heart of our body consists of which types of tissues?
The lesson states that the heart consists of all four types of tissues: epithelial, connective, muscular and neural.
Q7. In unicellular organisms, functions such as digestion, respiration and reproduction are performed by:
In unicellular organisms, all functions like digestion, respiration and reproduction are performed by a single cell.
Q8. The term morphology refers to the study of:
Morphology refers to the study of form or externally visible features.
Q9. In animals, the word anatomy is conventionally used for the study of:
The lesson states that anatomy is conventionally used for the study of morphology of internal organs in animals.
Q10. Cells, tissues, organs and organ systems split up the work in a way that exhibits:
The lesson explains that this hierarchy exhibits division of labour and contributes to the survival of the body as a whole.
Q11. The body of a simple organism like Hydra is made of:
The lesson notes that Hydra is made of different types of cells and the number of cells in each type can be in thousands.
Q12. According to the lesson, each organ in our body is made of:
The lesson states that each organ in our body is made of one or more types of tissues.
Q13. The four basic tissues are organised in specific proportion and pattern to form:
The lesson states that the four basic tissues are organised in specific proportion and pattern to form an organ like the stomach, lung, heart and kidney.
Q14. The human body is composed of:
The lesson states that the human body is composed of billions of cells to perform various functions.
Q15. The discernable trend seen in the complexity of organs and organ systems is called:
The lesson names this discernable trend the evolutionary trend, to be studied in detail in class XII.
