Questions and Answers
- 1.
What controls most of the cell processes and contains the hereditary information of DNA.
- A.
Mitochondria
- B.
Chloroplast
- C.
Nucleus
- D.
Nucleolus
Correct Answer
C. NucleusExplanation
The nucleus controls most of the cell processes and contains the hereditary information of DNA. It acts as the command center of the cell, regulating gene expression and controlling the synthesis of proteins and other molecules essential for cell function. The hereditary information stored in DNA is responsible for transmitting genetic traits from one generation to the next, and the nucleus plays a crucial role in maintaining and transmitting this information. Mitochondria and chloroplasts have their own DNA but do not contain the complete set of genetic information needed for cell processes. The nucleolus, on the other hand, is involved in the production of ribosomes and not in controlling cell processes or storing hereditary information.Rate this question:

Cell membranes are constructed mainly of
- A.
Lipid bilayers
- B.
Protein pumps
- C.
Carbohydrates
- D.
Peripheral proteins
Correct Answer
A. Lipid bilayersExplanation
Cell membranes are primarily composed of lipid bilayers, which consist of two layers of phospholipids arranged with their hydrophilic heads facing outward and their hydrophobic tails facing inward. This arrangement forms a barrier that separates the inside of the cell from its external environment. Lipid bilayers provide the structural integrity of the cell membrane and regulate the movement of substances in and out of the cell. While proteins, carbohydrates, and peripheral proteins also play important roles in cell membranes, lipid bilayers are the main component responsible for their structure and function.Rate this question:

Lipids have a hydrophobic head and two hydrophillic tails.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Lipids have a hydrophobic tail and a hydrophilic head. This arrangement allows them to form structures such as cell membranes, where the hydrophobic tails face inward and the hydrophilic heads face outward towards the aqueous environment. Therefore, the statement that lipids have a hydrophobic head and two hydrophilic tails is incorrect.Rate this question:

Which cell structures are someitmes found attached to the endoplasmic reticulum?
- A.
Chloroplasts
- B.
Mitochondria
- C.
Vacuoles
- D.
Ribosomes
Correct Answer
D. RibosomesExplanation
Ribosomes are sometimes found attached to the endoplasmic reticulum. This is because the endoplasmic reticulum plays a crucial role in protein synthesis, and ribosomes are the cellular structures responsible for protein synthesis. The attachment of ribosomes to the endoplasmic reticulum allows for the efficient transport of newly synthesized proteins into the ER for further processing and modification. This association between ribosomes and the endoplasmic reticulum is essential for the proper functioning of protein synthesis and secretion in the cell.Rate this question:

A salt water solution would be ____________________ to a pure water solution.
Correct Answer
hypertonicExplanation
A salt water solution would be hypertonic to a pure water solution because it has a higher concentration of solutes (salt) compared to the pure water. This causes water molecules to move from an area of lower solute concentration (pure water) to an area of higher solute concentration (salt water), resulting in a net movement of water out of the pure water solution and into the salt water solution.Rate this question:
- 19.
Peripheral proteins are structures that can transport material all the way through the cell membrane
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Peripheral proteins are not responsible for transporting material all the way through the cell membrane. Instead, they are found on the surface of the cell membrane and are loosely attached to either the inner or outer surface of the membrane. These proteins play various roles such as cell signaling, enzymatic activity, and structural support, but they do not transport material across the membrane.Rate this question:

Osmosis is the diffusion of water through a selectively permeable membrane.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Osmosis is the process by which water molecules move from an area of higher concentration to an area of lower concentration through a selectively permeable membrane. This movement occurs to equalize the concentration of solute on both sides of the membrane. Therefore, the statement that osmosis is the diffusion of water through a selectively permeable membrane is true.Rate this question:
