Cells, Tissues, And Membranes
Questions and Answers
- 1.
There are over 300 different types of cells.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement "There are over 300 different types of cells" is false. The human body consists of hundreds of different types of cells, not just 300. Each type of cell has a specific structure and function, contributing to the overall functioning of the body. Therefore, the given statement is incorrect.Rate this question:

The only difference between Cuboidal and Columnar cells are that the Nucleus in Columnar cells is taler and more slender.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because it states that the only difference between Cuboidal and Columnar cells is the size and shape of the nucleus. This implies that all other characteristics of these cells, such as their structure, function, and other organelles, are similar. Therefore, the statement accurately reflects the difference between these two types of cells.Rate this question:

Cardiac cells and Neural cells only grow in the heart and the brain.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Cardiac cells and neural cells are specialized cells that are found exclusively in the heart and brain respectively. Cardiac cells make up the muscles of the heart and are responsible for its contraction, while neural cells are the building blocks of the nervous system and are involved in transmitting and processing information in the brain. Therefore, it is true that these cells only grow in their respective organs, the heart and the brain.Rate this question:

The neuron is a tissue and not a cell.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is incorrect. A neuron is not a tissue, but rather a specialized type of cell that is responsible for transmitting information in the nervous system. Neurons are the building blocks of the nervous system and are found in the brain, spinal cord, and throughout the body. They have a unique structure and function that allows them to receive, process, and transmit electrical and chemical signals. Therefore, the correct answer is False.Rate this question:

Membranes regulate what enters and exits the cell.
- A.
True
- B.
Fasle
Correct Answer
A. TrueExplanation
Membranes in cells serve as a barrier that controls the movement of substances in and out of the cell. They have selective permeability, meaning they allow certain molecules to pass through while preventing others from entering or exiting. This regulation is crucial for maintaining the internal environment of the cell and ensuring that essential molecules are taken in and waste products are removed. Therefore, the statement "Membranes regulate what enters and exits the cell" is true.Rate this question:

Cells have three forms which of the following forms is not a cell but a tissue.
- A.
Squamous
- B.
Cuboidal
- C.
Columnar
- D.
Adipose
Correct Answer
D. AdiposeExplanation
Adipose is not a form of a cell, but rather a type of connective tissue. Adipose tissue is responsible for storing energy in the form of fat and providing cushioning and insulation to the body. It is composed of adipocytes, which are specialized cells that store and release fat. Squamous, cuboidal, and columnar, on the other hand, are all forms of epithelial cells that make up the lining of various organs and tissues in the body.Rate this question:

Cells are made up mostly of...
- A.
Lipids
- B.
Water
- C.
Carbohydrates
- D.
Proteins
Correct Answer
B. WaterExplanation
Cells are made up mostly of water because water is a vital component of all living organisms. It makes up a significant portion of the cell's cytoplasm and is involved in various cellular processes such as transportation, chemical reactions, and maintaining cell structure. Water also acts as a solvent, allowing for the dissolution and transport of various molecules within the cell. Additionally, water plays a crucial role in regulating temperature and providing a medium for metabolic reactions to occur.Rate this question:

Three are examples of muscle tissue, which is not.
- A.
Skeletal
- B.
Cardiac
- C.
Smooth
- D.
Neural
Correct Answer
D. NeuralExplanation
The given options are examples of different types of muscle tissue, except for neural tissue. Neural tissue refers to the tissue that makes up the nervous system, including the brain and spinal cord. Unlike muscle tissue, neural tissue is responsible for transmitting and processing information rather than generating force or movement. Therefore, neural tissue is not an example of muscle tissue.Rate this question:

Cells cant...
- A.
Copies genetic code
- B.
Dispose of waste
- C.
Make molecules it needs to survive, work and grow
- D.
None of the above
Correct Answer
D. None of the aboveExplanation
Cells are capable of all the mentioned functions. They can copy genetic code through processes like DNA replication. They dispose of waste through mechanisms like excretion and autophagy. Additionally, cells can synthesize molecules that are necessary for their survival, work, and growth through various metabolic pathways. Therefore, the correct answer is not "None of the above" as cells can perform all the mentioned functions.Rate this question:

The study of Tissues is called.
- A.
Histology
- B.
Tissuology
- C.
Radiology
- D.
Cardiology
Correct Answer
A. HistologyExplanation
Histology is the correct answer because it is the study of tissues. It involves examining the structure, composition, and function of different types of tissues in the body. Histologists use various techniques to analyze tissues, such as staining and microscopy, to understand their cellular organization and how they contribute to the overall functioning of organs and systems. This field of study is important for diagnosing diseases, understanding developmental processes, and advancing medical research.Rate this question:
