Hello and welcome to this science cells quiz that we've designed below to test your knowledge. The term “science” covers an incredibly broad range of topics and studies about the various facets of our universe; whether it’s a look at something as vast as space and the world we live in, or something as microscopic as the cell, science covers it all. Today we’ll be focusing on the latter in this cells quiz, as we test your knowledge on the little cell that makes up our bodies.
Cell Structures Questions and Answers
- 1.
What is the jelly-like substance found inside a cell?
- A.
Cytoplasm
- B.
Chloroplast
- C.
Nucleus
- D.
Cell membrane
Correct Answer
A. CytoplasmExplanation
Cytoplasm is the jelly-like substance found inside a cell. It is responsible for holding the cell's organelles in place and providing a medium for various cellular processes to occur. It contains water, ions, proteins, and other molecules necessary for cell metabolism and growth. The cytoplasm also acts as a buffer, protecting the cell's organelles from damage. Therefore, cytoplasm is the correct answer to the question.Rate this question:

What cells does a plant cell have, but an animal cell does not?
- A.
Nucleus and cell membrane
- B.
Cell wall and cytoplasm
- C.
Cell wall and chloroplast
- D.
Cell wall and nucleus
Correct Answer
C. Cell wall and chloroplastExplanation
A plant cell has a cell wall and chloroplasts, which are not present in an animal cell. The cell wall provides structural support and protection to the plant cell, while chloroplasts are responsible for photosynthesis, the process by which plants convert sunlight into energy. Animal cells do not have a cell wall because they do not require the same level of structural support, and they do not have chloroplasts because they obtain energy through other means such as consuming food.Rate this question:

The ____ controls all the activities in the cell.
Correct Answer
nucleusExplanation
The nucleus is the control center of the cell. It contains the cell's DNA and is responsible for regulating all the activities within the cell. It controls the synthesis of proteins, cell division, and the overall functioning of the cell. Without the nucleus, the cell would not be able to carry out its essential functions and would not be able to survive.Rate this question:
- 4.
The animal cell consists of _______, ________, and ___________.
Correct Answer
cell membrane, cytoplasm, and the nucleus. , cell membrane, cytoplasm, nucleus.Explanation
The animal cell is made up of three main components: cell membrane, cytoplasm, and the nucleus. The cell membrane surrounds the cell, acting as a barrier and controlling the movement of substances in and out of the cell. The cytoplasm is the gel-like substance that fills the cell, providing support and allowing for the movement of organelles within the cell. The nucleus is the control center of the cell, containing the genetic material and regulating cell activities. These three components are essential for the functioning and survival of the animal cell.Rate this question:
- 5.
The plant cell consists of _____, ______, _______, ________ and _______
Correct Answer
Cell membrane (plasma membrane), Cytoplasm, Nucleus, Cell Wall, and Chloroplasts (in photosynthetic plant cells)Explanation
The plant cell is composed of several structures that are essential for its functioning. The cell membrane acts as a protective barrier and controls the movement of substances in and out of the cell. The cell wall provides structural support and protection to the cell. The nucleus contains the genetic material and controls the cell's activities. The cytoplasm is a gel-like substance where various cellular processes occur. Chloroplasts are responsible for photosynthesis, converting sunlight into energy. Together, these components make up the plant cell and enable it to carry out its functions effectively.Rate this question:

Which of the following organisms reproduce by budding?
- A.
Yeast
- B.
Amoeba
- C.
Paramecium
- D.
Bacterium
Correct Answer
A. YeastExplanation
Yeast reproduces by budding. Budding is a form of asexual reproduction where a new organism grows as an outgrowth or bud from the parent organism. In yeast, a small bud forms on the parent cell, which eventually grows and detaches, becoming a new individual. This process allows for rapid reproduction and population growth in yeast colonies. Amoeba, Paramecium, and Bacterium reproduce through other methods such as binary fission or conjugation.Rate this question:

A plant cell can make its food because it has _____.
- A.
Cytoplasm
- B.
A cell membrane
- C.
Chloroplasts
- D.
A cell wall
Correct Answer
C. ChloroplastsExplanation
Plant cells have chloroplasts, which contain a pigment called chlorophyll. Chlorophyll is responsible for capturing sunlight and converting it into energy through the process of photosynthesis. This energy is used by the plant cell to produce its own food in the form of glucose. Therefore, chloroplasts are essential for a plant cell to make its own food.Rate this question:

The part of a plant cell that gives it a regular shape is the _____.
- A.
Cell membrane
- B.
Chloroplasts
- C.
Cell wall
- D.
Cytoplasm
Correct Answer
C. Cell wallExplanation
The cell wall is the correct answer because it provides structure and support to plant cells, giving them a regular shape. The cell membrane is responsible for controlling what enters and exits the cell, but it does not contribute to the shape of the cell. Chloroplasts are responsible for photosynthesis and are not involved in maintaining cell shape. Cytoplasm is the fluid inside the cell where various cellular processes occur, but it does not play a role in shaping the cell.Rate this question:

- 9.
When one cell divides into new cells to reproduce. This process is called _____.
- A.
Cell production
- B.
Cell division
- C.
Cell addition
- D.
Cell subtraction
Correct Answer
B. Cell divisionExplanation
Cell division is the correct answer because it refers to the process in which one cell divides into two or more daughter cells. This process is essential for growth, development, and the repair of tissues in multicellular organisms. During cell division, the genetic material is evenly distributed between the daughter cells to ensure that they each have a complete set of chromosomes.Rate this question:

Which of the following(s) is/are made up of only one cell?
- A.
Yeast
- B.
Bacterium
- C.
Paramecium
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
All of the options listed (yeast, bacterium, and paramecium) are made up of only one cell. Yeast is a type of fungus that consists of a single cell, while bacterium refers to a single-celled microorganism. Paramecium is a unicellular organism belonging to the group of ciliates. Therefore, all of the options mentioned are examples of organisms that are composed of a single cell.Rate this question:
