Cell Quiz (Easy)

1. Plant cells and Animal cells are different

True

False

Plant cells and animal cells are different because they have distinct structures and functions. Plant cells have a rigid cell wall made of cellulose, which provides support and protection. They also have chloroplasts for photosynthesis and a large central vacuole for storing water and nutrients. Animal cells do not have a cell wall or chloroplasts, and their vacuoles are smaller. Additionally, plant cells have plasmodesmata, which are channels that allow for communication between adjacent cells, while animal cells have gap junctions for cell communication. These differences in structure and organelles allow plant and animal cells to perform their specific functions in different ways.

2. Does an animal cell need nutrients?

Yes

No

Animal cells require nutrients for their growth, survival, and functioning. Nutrients provide the necessary energy and building blocks for cellular processes such as metabolism, reproduction, and repair. Without nutrients, animal cells would not be able to carry out essential functions and would eventually die. Therefore, the answer is yes, an animal cell needs nutrients.

3. The nucleus controls the cell.

True

False

The nucleus is the control center of the cell. It contains the cell's genetic material, including DNA, which provides instructions for the cell's activities. The nucleus also regulates the cell's functions by directing the synthesis of proteins and coordinating cell division. Therefore, it can be concluded that the statement "The nucleus controls the cell" is true.

4. What does the Cell wall do?

Store Nutrients

Protect cell

Fight bacteria

The cell wall provides protection to the cell by forming a rigid outer layer. It acts as a barrier, preventing the entry of harmful substances and protecting the cell from mechanical damage. The cell wall also helps maintain the shape and structure of the cell, providing support and stability. Additionally, it allows for communication and interaction between neighboring cells.

5. What does the cell do?

Fight sickness

Keep you alive

All of the above

The cell plays a vital role in keeping a person alive. It carries out various functions necessary for survival, such as producing energy, replicating DNA, and regulating bodily processes. Additionally, cells are involved in fighting off sickness by participating in the immune response and defending the body against pathogens. Therefore, the correct answer is "Keep you alive" as it encompasses both the essential functions of cells.
