Questions and Answers

1.

Does not have a cell wall and has contriulaer
- A.
  
  Animal cell
- B.
  
  Cell
- C.
  
  Cell membrane
- D.
  
  Cell wall
Correct Answer
A. Animal cell

Explanation
The correct answer is an animal cell because animal cells do not have a cell wall. Instead, they have a cell membrane which is a flexible and selectively permeable barrier that surrounds the cell and regulates the movement of substances in and out of the cell. The absence of a cell wall allows animal cells to be more flexible in shape and allows for various cellular functions such as cell movement and cell communication.

Provide support and protection in plant cells.
- A.
  
  Chelroplast
- B.
  
  Cell membrane
- C.
  
  Cell wall
- D.
  
  Animal cell
Correct Answer
C. Cell wall

Explanation
The cell wall is a rigid structure that provides support and protection in plant cells. It surrounds the cell membrane and provides structural stability, preventing the cell from bursting under pressure. The cell wall also acts as a barrier, protecting the cell from external threats such as pathogens. Additionally, the cell wall allows for the exchange of water, nutrients, and waste materials between cells. In contrast, animal cells do not have a cell wall, and instead rely on the cell membrane for support and protection.

3.

Basic unit of life.
- A.
  
  Cell membrane
- B.
  
  Animal cell
- C.
  
  Cell wall
- D.
  
  Cells
Correct Answer
D. Cells

Explanation
Cells are considered the basic unit of life because they are the smallest structural and functional unit of living organisms. All living things are made up of cells, which are responsible for carrying out essential life processes such as metabolism, growth, and reproduction. Cells can vary in size, shape, and function, but they all have certain characteristics in common, such as a cell membrane that regulates the passage of substances in and out of the cell. Both animal cells and plant cells have cell membranes, but only plant cells have an additional rigid cell wall surrounding the cell membrane. Therefore, the correct answer is cells.

The site of photosynthesis is:
- A.
  
  Chloroplast
- B.
  
  Animal cell
- C.
  
  Cell
- D.
  
  Cell wall
Correct Answer
A. Chloroplast

Explanation
Chloroplasts are organelles found in plant cells that contain the green pigment chlorophyll. Chlorophyll absorbs light energy from the sun, which is essential for the process of photosynthesis. Photosynthesis converts light energy into chemical energy in the form of glucose, which plants use for growth and other functions.

Boudry of cell controls what enter and leave.
- A.
  
  Cell membrane
- B.
  
  Cell wall
- C.
  
  Chelroplast
- D.
  
  Animal cell
Correct Answer
A. Cell membrane

Explanation
The cell membrane is responsible for controlling what enters and leaves the cell. It acts as a barrier, selectively allowing certain substances to pass through while blocking others. This selective permeability is crucial for maintaining homeostasis within the cell and regulating the movement of molecules and ions. The cell membrane is composed of a phospholipid bilayer with embedded proteins that play a role in transport and communication. Unlike the cell wall, which provides structural support, the cell membrane is dynamic and flexible, allowing it to regulate the exchange of materials with the external environment.

What are living considered as living things.other than humans.
- A.
  
  Humans
- B.
  
  Trees
- C.
  
  Rocks
- D.
  
  Leaves
Correct Answer
D. Leaves

Explanation
Leaves are considered living things because they exhibit characteristics of life. They are composed of cells, can grow and develop, and perform functions such as photosynthesis and respiration. Leaves also respond to stimuli, such as turning towards light or closing in response to touch. Unlike rocks, which are non-living and do not possess these characteristics, leaves are living organisms that play a vital role in the survival of plants.

What are considered as non-living things.
- A.
  
  Plants
- B.
  
  Bricks
- C.
  
  Humans
- D.
  
  Animals
Correct Answer
B. Bricks

Explanation
Bricks are considered as non-living things because they are man-made objects that do not possess life or biological functions. Unlike plants, animals, and humans, which are living organisms capable of growth, reproduction, and response to stimuli, bricks are inert materials that do not exhibit any signs of life.
