Science 6: Animal Cell Vs. Plant Cell Quiz

1.

___________ = control center of the cell

Explanation
The nucleus is considered the control center of the cell because it contains the cell's genetic material, including DNA, which carries the instructions for the cell's activities and functions. It regulates the cell's growth, reproduction, and overall metabolism. The nucleus also plays a crucial role in gene expression and protein synthesis, as it houses the machinery necessary for these processes. Additionally, the nucleus controls the movement of molecules in and out of the cell through its nuclear envelope and pores. Overall, the nucleus is essential for maintaining the cell's structure and coordinating its activities.

_________ = represents human skin, but acts as the protective covering for the cell.

Explanation
The cell membrane is the correct answer because it is a protective covering for the cell and it also represents human skin. The cell membrane acts as a barrier, controlling the movement of substances in and out of the cell, and providing stability and protection for the cell's internal environment. Similarly, human skin acts as a protective covering for the body, regulating the exchange of substances and protecting against external threats. Therefore, the cell membrane can be seen as the equivalent of human skin in a cell.

3.

_______ = gives cushion to the cell as to not harm the inner organelles

Explanation
Cytoplasm is the correct answer because it provides a cushioning effect to the cell, preventing any potential harm to the inner organelles. The cytoplasm is a gel-like substance that fills the cell and surrounds the organelles, providing support and protection. It also facilitates the movement of nutrients, proteins, and other molecules within the cell.

_______ = allows the plant cell to be rigid and a strong

Explanation
The cell wall is responsible for providing rigidity and strength to plant cells. It acts as a protective barrier and helps maintain the shape of the cell. The cell wall is made up of cellulose fibers and other components that give it its strength. Without the cell wall, plant cells would be unable to maintain their shape and would be more susceptible to damage.

Muscles and heart are to humans, as ________ are to the plant and animal cell

6.

This organelle is responsible for producing a green pigment in a plant cell = _______

Explanation
The cytoplasm is not responsible for producing a green pigment in a plant cell. The correct answer should be chloroplasts. Chloroplasts contain a pigment called chlorophyll, which gives plants their green color and is responsible for photosynthesis.

7.

_____= is the name for the green pigment in a plant cell

Explanation
Chlorophyll is the correct answer because it is the name for the green pigment in a plant cell. Chlorophyll is responsible for absorbing light energy from the sun, which is then used in the process of photosynthesis to convert carbon dioxide and water into glucose and oxygen. This pigment gives plants their green color and is essential for their ability to produce food through photosynthesis.

8.

The plant cell has a _ shaped compared to animal cell that has a ___ shape

Explanation
The plant cell has a square shape compared to the animal cell that has a circular shape. This is because plant cells have a rigid cell wall made of cellulose that provides structural support, giving them a more defined shape. On the other hand, animal cells do not have a cell wall and are more flexible, allowing them to take on a rounded shape.

9.

Animal cells have a cell membrane

A.

True
B.

False

Correct Answer
A. True

Explanation
Animal cells have a cell membrane that acts as a protective barrier, regulating the movement of substances in and out of the cell. The cell membrane is composed of a phospholipid bilayer with embedded proteins, which allows for selective permeability and helps maintain the cell's internal environment. This structure is essential for the cell's survival and function, making the statement "Animal cells have a cell membrane" true.

10.

Animal cells have a cell wall

A.

True
B.

False

Correct Answer
B. False

Explanation
Animal cells do not have a cell wall. Unlike plant cells, animal cells are surrounded by a flexible plasma membrane that allows for movement and flexibility. The absence of a cell wall in animal cells enables them to change shape and perform various functions such as engulfing particles and forming tissues and organs.

11.

Cell membrane is like a gatekeeper

A.

True
B.

False

Correct Answer
A. True

Explanation
The cell membrane acts as a gatekeeper because it controls the movement of substances in and out of the cell. It is selectively permeable, allowing certain molecules to pass through while preventing others from entering or exiting. This regulation is crucial for maintaining the cell's internal environment and ensuring proper functioning. Therefore, the statement "Cell membrane is like a gatekeeper" is true.

Rate this question:

12.

_____ = storage place for the cell

Correct Answer
Vacuole, vacuole, Vacuoles, vacuoles

Explanation
Vacuoles are membrane-bound organelles found in both animal and plant cells, though they are typically larger in plant cells. They serve as storage compartments for various substances, including water, nutrients, waste products, and enzymes. Vacuoles play a crucial role in maintaining cell shape, turgor pressure, and intracellular digestion.

In animal cell, the _______ is the powerhouse of the animal cell, responsible for producing energy.

Correct Answer
Mitochondria, mitochondria

Explanation
Mitochondria are often referred to as the "powerhouses" of the cell because they generate most of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy. Mitochondria are essential for cellular respiration, the process by which cells convert nutrients into usable energy. They are double-membraned organelles with their own DNA and are thought to have originated from ancient bacteria that were engulfed by eukaryotic cells. Sources and related content

Animal cells have a cell wall.

A.

True
B.

False

Correct Answer
B. False

Explanation
Animal cells do not have cell walls. This is a key distinction between animal and plant cells. Plant cells have rigid cell walls composed of cellulose that provide structural support and protection. Animal cells, on the other hand, lack cell walls and instead rely on their cell membranes and internal cytoskeleton for shape and support. This difference reflects the differing needs and functions of animal and plant cells in their respective environments.
