Biology Test

1. What is the liquid found inside the cell?

Correct answer: D

Rationale: The correct answer is D, Cytosol. Cytosol is the liquid component of the cytoplasm where various cellular processes occur. Choices A, B, and C are incorrect because the plasma membrane is the outer boundary of the cell, cilia are hair-like structures on the cell surface, and cytoplasm is the jelly-like substance that contains organelles within the cell, not the liquid inside the cell.

2. The bilayer of the cellular membrane consists of phospholipids with all except which of the following scattered throughout?

Correct answer: A

Rationale: The cellular membrane is composed of a phospholipid bilayer with cholesterol, proteins, and glycoproteins distributed throughout. Nucleic acids are not found within the cellular membrane. Cholesterol helps maintain membrane fluidity, while proteins and glycoproteins play important roles in cell signaling, transport, and structural support.

3. Which of the following options identifies the products of cell respiration?

Correct answer: C

Rationale: The correct answer is C: 'Water, carbon dioxide, and adenosine triphosphate (ATP).' During cellular respiration, glucose is broken down in the presence of oxygen to produce water, carbon dioxide, and ATP. Choice A is incorrect as oxygen is not a product of cell respiration but a reactant. Choice B is incorrect as it lists glucose and oxygen, which are actually reactants in the process. Choice D is incorrect as glucose is not a product of cell respiration but a substrate that is broken down to release energy.

4. What is located on the rough endoplasmic reticulum?

Correct answer: D

Rationale: The rough endoplasmic reticulum is studded with ribosomes, which are responsible for protein synthesis. Ribosomes are the correct answer because they are the organelles directly associated with the rough endoplasmic reticulum. Microvilli (choice A), mitochondria (choice B), and lysosomes (choice C) are not typically located on the rough endoplasmic reticulum. Microvilli are found on the surface of cells to increase surface area, mitochondria are the powerhouses of the cell responsible for energy production, and lysosomes are membrane-bound organelles containing digestive enzymes.

5. Which of the following is the process that reduces cells originally classified as diploid to haploid?

Correct answer: A

Rationale: The correct answer is A, Meiosis. Meiosis is the cell division process that reduces the chromosome number from diploid to haploid, which is essential for sexual reproduction. Choice B, Photosynthesis, is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll. Choice C, Mitosis, is a cell division process that results in two diploid daughter cells with the same number of chromosomes as the parent cell. Choice D, Cytokinesis, is the division of the cytoplasm following cell division.
