Essential Cell Biology Vocabulary Quiz

1. What term describes an organism made up of only one cell?

Bicellular

Microbial

Unicellular

Multicellular

Unicellular organisms consist of a single cell, while multicellular organisms are made up of multiple cells. 'Bicellular' and 'Microbial' are not correct terms to describe single-celled organisms.

Explanation

Unicellular organisms consist of a single cell, while multicellular organisms are made up of multiple cells. 'Bicellular' and 'Microbial' are not correct terms to describe single-celled organisms.

2. What is the term for an individual living thing?

Organism

Ecosystem

Cell

Species

An organism refers to an individual living thing, different from species (a group of organisms with similar characteristics), cell (the basic unit of life), and ecosystem (a community of living organisms interacting with each other and their environment).

Explanation

An organism refers to an individual living thing, different from species (a group of organisms with similar characteristics), cell (the basic unit of life), and ecosystem (a community of living organisms interacting with each other and their environment).

3. What term describes an organism made up of more than one cell?

Multicellular

Monocellular

Unicellular

Single-celled

Multicellular organisms are made up of more than one cell, in contrast to unicellular organisms which consist of a single cell.

Explanation

Multicellular organisms are made up of more than one cell, in contrast to unicellular organisms which consist of a single cell.

4. A group of similar cells that work together to do the same job is known as?

Tissues

Organs

Cells

Organisms

Tissues are groups of cells that work together to perform a specific function, while organs are made up of tissues working together, organisms are individual living entities, and cells are the basic building blocks of living organisms.

Explanation

Tissues are groups of cells that work together to perform a specific function, while organs are made up of tissues working together, organisms are individual living entities, and cells are the basic building blocks of living organisms.

5. A group of similar tissues that work together to perform a specific body function is called?

Cell

System

Organ

Organism

Tissues are groups of cells that work together to perform a specific function. Organs are made up of different types of tissues working together. Systems consist of multiple organs working together. An organism is a complete individual living entity.

Explanation

Tissues are groups of cells that work together to perform a specific function. Organs are made up of different types of tissues working together. Systems consist of multiple organs working together. An organism is a complete individual living entity.

6. What is a group of organs that work together to perform a specific body function?

Body formation

Organ system

Tissue bundle

Cell cluster

An organ system is a group of organs that work together to perform specific functions in the body. It involves the coordination of multiple organs to carry out a particular task, such as the respiratory system or the digestive system.

Explanation

An organ system is a group of organs that work together to perform specific functions in the body. It involves the coordination of multiple organs to carry out a particular task, such as the respiratory system or the digestive system.

7. Place the following in correct order: Cell -> tissue -> organ -> organ system -> organism.

Organ system -> organ -> cell -> tissue -> organism

Organ -> cell -> tissue -> organism -> organ system

Tissue -> cell -> organ -> organism -> organ system

Cell -> tissue -> organ -> organ system -> organism

The correct order starts from the basic unit of life, the cell, and progresses to tissues, organs, organ systems, and finally to an organism as a whole.

Explanation

The correct order starts from the basic unit of life, the cell, and progresses to tissues, organs, organ systems, and finally to an organism as a whole.

8. What are the two primary plant organ systems?

Leaf system and stem system

Flower system and fruit system

Root system and shoot system

Branch system and vine system

Plants have two main organ systems - the root system responsible for anchoring and absorbing nutrients, and the shoot system responsible for photosynthesis and reproduction.

Explanation

Plants have two main organ systems - the root system responsible for anchoring and absorbing nutrients, and the shoot system responsible for photosynthesis and reproduction.

9. Which of the following are animal organ systems?

Nervous system, skeletal system, muscular system

Integumentary system, reproductive system, immune system

Endocrine system, lymphatic system, excretory system

Digestive system, circulatory system, respiratory system, etc.

Animal organ systems are groups of organs that work together to perform specific functions in the body. The correct answer includes systems responsible for digestion, transportation of nutrients and waste, and breathing. The incorrect answers list different organ systems that are not part of the main animal organ systems.

Explanation

Animal organ systems are groups of organs that work together to perform specific functions in the body. The correct answer includes systems responsible for digestion, transportation of nutrients and waste, and breathing. The incorrect answers list different organ systems that are not part of the main animal organ systems.

10. How do cells work together?

They work together to perform the same task for the body.

Cells have no role in the overall functioning of the body.

Cells work against each other in a competitive manner.

Cells work independently without any coordination.

Cells work in a coordinated manner to carry out specific functions required for the overall health and functioning of the body. This orchestrated effort ensures that different cell types collaborate to achieve common goals and support the various processes necessary for life.
