Cell Biology Essentials Quiz

1. What is cytoplasm and what is its function?

3. Cytoplasm is a specialized organelle responsible for energy production within the cell.

1. Cytoplasm is a solid structure that only provides structural support to the cell.

2. Cytoplasm is a type of genetic material responsible for carrying hereditary information.

Cytoplasm is not a solid structure, does not carry hereditary information, and is not responsible for energy production. It is a gel-like substance where most cellular chemical reactions occur, and it contains various organelles essential for cell functioning.

Explanation

Cytoplasm is not a solid structure, does not carry hereditary information, and is not responsible for energy production. It is a gel-like substance where most cellular chemical reactions occur, and it contains various organelles essential for cell functioning.

2. What is protoplasm and name the four elements which make up the major part of protoplasm?

Protoplasm is a type of gas composed of helium, neon, argon, and krypton.

Protoplasm is made up of gold, silver, copper, and zinc.

The cytoplasm is the only element that makes up protoplasm.

Protoplasm is the living material comprising the entirety of a cell, including the cytoplasm and nucleus. It is made up of carbon, hydrogen, nitrogen, and oxygen, along with other compounds such as water, carbohydrates, proteins, fats, nucleic acids, and mineral salts. Incorrect answers do not accurately describe protoplasm or its composition.

3. What are unicellular organisms? Provide examples of two unicellular organisms.

Multicellular organisms are organisms made up of multiple cells.

Examples of unicellular organisms include fish and birds.

Unicellular organisms are organisms made up of two cells.

Unicellular organisms are defined by their composition of a single cell, allowing them to perform all essential life functions independently. Examples like amoeba and paramecium illustrate this characteristic.
