Cells is a science topic. You will learn this topic when you are in P6
Questions and Answers
- 1.
What is/are the cell part(s) that gives the shape to the cell?
- A.
Cell wall
- B.
Cell membrane
- C.
Nucleus
- D.
All of them above
Correct Answer
A. Cell wallExplanation
The cell wall is responsible for giving shape to the cell. It is a rigid layer that surrounds the cell membrane and provides support and protection to the cell. The cell membrane controls the movement of substances in and out of the cell, but it does not contribute to the shape of the cell. The nucleus, on the other hand, contains the cell's genetic material and is not involved in shaping the cell. Therefore, the correct answer is the cell wall.Rate this question:

What is the cell part that only plant cells have and animal cells do not have?
- A.
Cell membrane
- B.
Nucleus
- C.
Chlorophyll
- D.
None of them above
Correct Answer
C. ChlorophyllExplanation
Chlorophyll is the correct answer because it is a pigment found in plant cells that is responsible for capturing sunlight and converting it into energy through photosynthesis. Animal cells do not have chlorophyll as they do not undergo photosynthesis. The cell membrane and nucleus are present in both plant and animal cells.Rate this question:

What is/are plant part(s) that controls all the activities in the cell?
- A.
All of them below
- B.
Cell membrane
- C.
Nucleus
- D.
Nucleus and cell membrane
- E.
Non of them above
Correct Answer
C. NucleusExplanation
The nucleus is the correct answer because it is the control center of the cell. It contains the cell's DNA and directs all cellular activities, including growth, reproduction, and metabolism. The cell membrane, on the other hand, acts as a barrier and regulates the movement of substances in and out of the cell, but it does not control all the activities within the cell. Therefore, the correct answer is the nucleus.Rate this question:

What is the cell membrane for?
- A.
To keep good stuff in and bad stuff out.
- B.
To make the cell look nice
- C.
To make the cell look big
- D.
All of them above
- E.
None of them above
Correct Answer
A. To keep good stuff in and bad stuff out.Explanation
The cell membrane serves as a selective barrier that regulates the movement of substances in and out of the cell. It allows essential nutrients and molecules to enter the cell, while preventing harmful substances from entering. This selective permeability helps maintain the internal environment of the cell and ensures its proper functioning. Therefore, the cell membrane's main purpose is to keep the good stuff in and the bad stuff out.Rate this question:

What is the process of splitting of cells?
- A.
Splitting
- B.
Budding
- C.
Cell division
- D.
All of them above
Correct Answer(s)
C. Cell division
D. All of them aboveExplanation
Cell division is the process of splitting cells. It involves the replication and division of the genetic material, followed by the physical separation of the cytoplasm and organelles to form two new daughter cells. Splitting and budding are specific types of cell division, where the parent cell divides into two or more daughter cells. Therefore, the correct answer is "cell division, all of them above".Rate this question:

What is in an animal cell?
- A.
Nucleus, cell membrane, cell wall, chloroplast, chlorophyll
- B.
nucleus, cell membrane, cytoplasm
- C.
None of them above
Correct Answer
B. nucleus, cell membrane, cytoplasmExplanation
The correct answer is nucleus, cell membrane, cytoplasm. An animal cell contains a nucleus, which is the control center of the cell. It also has a cell membrane, which acts as a protective barrier and controls the movement of substances in and out of the cell. The cytoplasm is the gel-like substance that fills the cell and contains various organelles and molecules necessary for cell function. The other options mentioned, such as cell wall, chloroplast, and chlorophyll, are not present in animal cells.Rate this question:

Is cells important to our body?
- A.
Yes
- B.
No
- C.
Maybe, maybe not
- D.
All of them above
Correct Answer
A. YesExplanation
Cells are indeed important to our body. They are the basic building blocks of life and make up all living organisms. Cells perform various functions such as growth, repair, and reproduction. They are responsible for carrying out essential processes like respiration, digestion, and metabolism. Additionally, cells play a crucial role in maintaining homeostasis and ensuring the proper functioning of organs and systems in the body. Without cells, the body would not be able to perform vital functions necessary for survival.Rate this question:

Why is chlorophyll useful to plants?
- A.
For photosynthesis
- B.
Chlorophyll is glucose(food for plants)
- C.
All of them above
- D.
None of them above
Correct Answer
A. For photosynthesisExplanation
Chlorophyll is useful to plants because it is essential for photosynthesis. Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Chlorophyll is the pigment that captures sunlight and initiates the chemical reactions necessary for photosynthesis to occur. Without chlorophyll, plants would not be able to produce their own food and survive.Rate this question:

Are all living things made up of cells?
- A.
No.
- B.
Yes
- C.
None of them above
- D.
Maybe
Correct Answer
B. YesExplanation
Yes, all living things are made up of cells. Cells are the basic structural and functional units of life. They are the building blocks of all living organisms, from simple single-celled organisms to complex multicellular organisms. Cells carry out essential functions such as growth, reproduction, and metabolism. Therefore, it can be concluded that all living things are composed of cells.Rate this question:

How can we look and study cells?
- A.
With glasses
- B.
With our naked eyes
- C.
With a microscope
- D.
None of them above
Correct Answer
C. With a microscopeExplanation
Cells are extremely small and cannot be seen with the naked eye. Therefore, the use of a microscope is necessary to observe and study cells. Microscopes are powerful tools that magnify the image of cells, allowing scientists to examine their structure, function, and behavior in detail. Using glasses or relying on our naked eyes would not provide sufficient magnification to visualize cells accurately.Rate this question:

The nucleus is only found in a plant cell.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because the nucleus is found in both plant and animal cells. The nucleus is a membrane-bound organelle that contains the cell's genetic material, including DNA. It is responsible for controlling the cell's activities and is present in all eukaryotic cells, which includes both plant and animal cells. Therefore, the statement that the nucleus is only found in a plant cell is incorrect.Rate this question:
