Introduction to Cells Questions and Answers

1.

A structure that is found in plant cells but not in animal cells is called a _______________.
- A.
  
  Nucleus
- B.
  
  Cell membrane
- C.
  
  Nuclear membrane
- D.
  
  Cell wall
Correct Answer
D. Cell wall

Explanation
A structure that is found in plant cells but not in animal cells is a cell wall. The cell wall is a rigid layer located outside the cell membrane in plant cells. It provides support and protection to the cell, helping it maintain its shape and preventing it from bursting under osmotic pressure. Animal cells do not have a cell wall, instead they have a flexible cell membrane that allows for movement and communication between cells.

2.

What structure is more in quantity as a cell becomes increasingly active?
- A.
  
  Ribosomes
- B.
  
  Chromosomes
- C.
  
  Mitochondria
- D.
  
  Vacuoles
Correct Answer
C. Mitochondria

Explanation
Mitochondria are the structures that are found in cells and are responsible for producing energy. The more active a cell is, the more energy it requires, and therefore it needs more mitochondria to meet its energy demands.

3.

The structure that allows materials to pass in and out of a cell is the _____________________.
- A.
  
  Cell membrane
- B.
  
  Nuclear membrane
- C.
  
  Endoplasmic reticulum
- D.
  
  Vacuole
Correct Answer
A. Cell membrane

Explanation
The cell membrane is a structure that surrounds and protects the cell, allowing materials to pass in and out. It is composed of a phospholipid bilayer with embedded proteins that regulate the movement of substances. The cell membrane is selectively permeable, meaning it allows certain molecules to enter or exit the cell while restricting others. This essential function of the cell membrane makes it the correct answer in this question.

The movement of water molecules from an area of greater concentration of water to an area of lesser concentration of water is called ________________________ .
- A.
  
  Mitosis
- B.
  
  Osmosis
- C.
  
  Diffusion
- D.
  
  Metabolism
Correct Answer
B. Osmosis

Explanation
Osmosis is the correct answer because it refers to the movement of water molecules from an area of higher concentration to an area of lower concentration. This process occurs across a semi-permeable membrane, allowing water to pass through while preventing the passage of solutes. Osmosis is essential for maintaining the balance of water in living organisms and plays a crucial role in various biological processes.

5.

The phase of mitosis during which the chromosome pairs line up along the middle, or the equator, of the cell is called _______________.
- A.
  
  Anaphase
- B.
  
  Prophase
- C.
  
  Telophase
- D.
  
  Metaphase
Correct Answer
D. Metaphase

Explanation
During metaphase, the chromosome pairs align themselves along the equator of the cell. This alignment is essential for the accurate segregation of chromosomes during cell division. The spindle fibers attach to the centromeres of the chromosomes and help in positioning them at the metaphase plate. Once the chromosomes are aligned, they are ready to be separated and pulled apart during anaphase. Therefore, metaphase is the correct phase of mitosis where the chromosome pairs line up along the middle of the cell.

Rate this question:
6.

The period of time during which a cell is not dividing is called ____________________.
- A.
  
  Interphase
- B.
  
  Telophase
- C.
  
  Anaphase
- D.
  
  Metaphase
Correct Answer
A. Interphase

Explanation
Interphase is the correct answer because it refers to the period of time in the cell cycle when the cell is not actively dividing. During interphase, the cell undergoes growth, DNA replication, and prepares for cell division. This phase is crucial for the cell to gather the necessary resources and energy for division. In contrast, telophase, anaphase, and metaphase are all stages of cell division and do not refer to the period of time when the cell is not dividing.

Rate this question:
7.

Which structures pass on the traits of a cell to new cells?
- A.
  
  Chromosomes
- B.
  
  Endoplasmic reticulum
- C.
  
  Mitochondria
- D.
  
  Ribosomes
Correct Answer
A. Chromosomes

Explanation
Chromosomes are the structures that contain the genetic information of a cell, including the traits that are passed on to new cells during cell division. They are made up of DNA and proteins, and they carry the instructions for the development and functioning of an organism. When a cell divides, the chromosomes replicate and are distributed equally to the new cells, ensuring that the traits of the original cell are passed on. Therefore, chromosomes play a crucial role in transmitting the traits of a cell to new cells.

Rate this question:
8.

Which level of organization goes from simplest to the most complex?
- A.
  
  Organism, cells, organ, organ system, tissues
- B.
  
  Cells, organs, tissues, organ system, organism
- C.
  
  Cells, tissues, organ system, organ, organism
- D.
  
  Cells, tissues, organs, organ systems, organism
Correct Answer
D. Cells, tissues, organs, organ systems, organism

Explanation
The correct answer is cells, tissues, organs, organ systems, organism. This is because cells are the basic building blocks of all living organisms. Multiple cells working together form tissues, which then combine to create organs. Organs work together in organ systems to perform specific functions, and all the organ systems together make up an organism. Therefore, this sequence represents the level of organization from simplest to most complex.

Rate this question:
9.

In what level of organization would you place the liver?
- A.
  
  Cells
- B.
  
  Organ
- C.
  
  Organ system
- D.
  
  Tissue
Correct Answer
B. Organ

Explanation
The liver is a complex structure composed of different tissues that perform specific functions. It is responsible for detoxifying chemicals, producing bile, storing vitamins and minerals, and regulating blood sugar levels. As an organ, it is made up of various types of tissues, such as hepatocytes, blood vessels, and connective tissue. These tissues work together to carry out the liver's functions. Therefore, the liver is correctly categorized as an organ.

Rate this question:
10.

In what level of organization would you place the digestive system?
- A.
  
  Cells
- B.
  
  Tissues
- C.
  
  Organs
- D.
  
  Organ system
Correct Answer
D. Organ system

Explanation
The digestive system is a collection of organs that work together to break down food and absorb nutrients. It includes organs such as the mouth, esophagus, stomach, small intestine, and large intestine. These organs work together to perform the specific function of digestion. Therefore, the correct level of organization to place the digestive system is at the organ system level.
