Unit Two: Cells Bacteria & Viruses: The Parts Of The Cell
A quick quiz on the Seven parts of the cell we learned in Biology this year. Good Luck!
- 1.
In an Eukaryotic cell, name the part of the cell that controls the entry and exit of substances and has a lipid bi layer
- A.
Cell Wall
- B.
Cell Membrane
- C.
Endoplasmic Reticulum
- D.
Microfilaments
- E.
None of the above
Correct Answer
B. Cell MembraneExplanation
The cell membrane is the correct answer because it is responsible for controlling the entry and exit of substances in an eukaryotic cell. It is composed of a lipid bilayer, which allows it to regulate the movement of molecules in and out of the cell. The cell membrane also plays a crucial role in maintaining the cell's internal environment and protecting it from external factors.Rate this question:

In a plant cell, what is the protection barrier that keeps the cell shape together?
- A.
Nucleus
- B.
Cell Membrane
- C.
Microtubules
- D.
Cell Wall
- E.
None of the Above
Correct Answer
D. Cell WallExplanation
The correct answer is Cell Wall. The cell wall is a rigid layer that surrounds the cell membrane in plant cells. It provides structural support and protection to the cell, helping to maintain its shape and prevent it from bursting or collapsing. The cell wall is made up of cellulose fibers and other components, and it also allows for the exchange of substances between neighboring cells. The nucleus, cell membrane, and microtubules are important components of the cell, but they do not specifically serve as the protection barrier that keeps the cell shape together in plant cells.Rate this question:

The Nucleus does...
- A.
Nothing
- B.
Directs the making of Protein
- C.
Provides energy for the cell
- D.
Stores energy for the cell
- E.
Gives the cell some color
Correct Answer
B. Directs the making of ProteinExplanation
The nucleus is responsible for directing the making of proteins in a cell. This is because it contains the cell's DNA, which carries the instructions for protein synthesis. The DNA is transcribed into messenger RNA (mRNA) in the nucleus, and then the mRNA is transported to the ribosomes in the cytoplasm, where protein synthesis occurs. Therefore, the nucleus plays a crucial role in protein production within the cell.Rate this question:

Inside the cell are these pathways for things to move through the cell called?
- A.
Golgi Bodies
- B.
Lysosomes
- C.
Cell Membrane
- D.
Pathology
- E.
Endoplasmic Reticulum
Correct Answer
E. Endoplasmic ReticulumExplanation
The endoplasmic reticulum is a network of membranes inside the cell that is responsible for the synthesis, folding, and transport of proteins and lipids. It consists of two types: rough endoplasmic reticulum (RER), which is studded with ribosomes and involved in protein synthesis, and smooth endoplasmic reticulum (SER), which lacks ribosomes and is involved in lipid metabolism and detoxification. The endoplasmic reticulum acts as a pathway for molecules to move within the cell, allowing for the efficient transport of proteins and lipids to their proper destinations.Rate this question:

This Maze-Like organelle provides energy for the cell. What is this organelle
- A.
Vacuoles
- B.
Ribosomes
- C.
Mitochondria
- D.
Flagella
- E.
None of the above
Correct Answer
C. MitochondriaExplanation
Mitochondria is the correct answer for this question because it is a maze-like organelle that provides energy for the cell. Mitochondria are often referred to as the powerhouse of the cell because they produce adenosine triphosphate (ATP), which is the main source of energy for cellular activities. They have a unique structure with inner and outer membranes, and their own DNA. Vacuoles are responsible for storage, ribosomes are involved in protein synthesis, and flagella are responsible for cell movement. Therefore, none of these options provide energy for the cell like mitochondria do.Rate this question:

What is the sac that stores water, food, and waste inside a plant cell?
- A.
Storage Sac
- B.
Chloroplasts
- C.
Cilia
- D.
Vacuum
- E.
Vacuoles
Correct Answer
E. VacuolesExplanation
Vacuoles are the sacs that store water, food, and waste inside a plant cell. They are membrane-bound organelles that play a crucial role in maintaining the cell's shape and turgidity. Vacuoles also serve as storage compartments for nutrients, ions, and waste products. They help regulate the cell's internal environment, control osmotic pressure, and aid in the breakdown and recycling of cellular waste materials. Therefore, vacuoles are responsible for storing and managing various substances within a plant cell.Rate this question:

The double membrane Chloroplast located in a plant cell does what?
- A.
Absourbs photosynthesis
- B.
Uses sun energy
- C.
Give Color
- D.
All of the above
- E.
None of the above
Correct Answer
D. All of the aboveExplanation
The double membrane chloroplast located in a plant cell performs multiple functions. It absorbs sunlight through the pigment chlorophyll, which is essential for photosynthesis. This process converts sunlight into chemical energy, allowing the plant to produce glucose and oxygen. Additionally, chloroplasts contain pigments other than chlorophyll, giving plants their characteristic green color. Therefore, the correct answer is "All of the above" as the chloroplast is involved in absorbing photosynthesis, using sun energy, and giving color to plants.Rate this question:
