Quiz Answer Key and Fun Facts

1. Which pair of compounds can be classified as inorganic?

Answer: water and salts.

Organic compounds contain carbon and hydrogen bonds. Both nucleic acids and proteins contain these. Water (H2O) and salts (ex: NaCl) do not.

2. Which are the four most abundant elements in living cells?

Answer: carbon, oxygen, hydrogen, nitrogen.

Although all of these elements are found in living cells, the most abundant are carbon, hydrogen and oxygen (for carbohydrates and lipids) and nitrogen (for proteins and nucleic acids).

3. Which is an organic compound found in most cells?

Answer: glucose.

Organic means that the molecule contains carbon bonded to hydrogen. Only glucose, whose molecular formula is C6H12O6, has this. Although most cells also have an abundant amount of water (H2O) it is inorganic, as is sodium chloride (NaCl) and oxygen gas (O2).NH3

4. Which formula represents an organic compound?

Answer: C12H22O11.

Organic compounds have Carbon C and Hydrogen H and Oxygen O are part of, or produced by, or excreted by living organisms.

5. Which structure is usually present only in animal cells?

Answer: centriole.

Animal cells contain centrioles, cylindrical organelles that direct the movement of the chromosomes during mitosis. Plant cells tend to have bigger vacuoles and they also have rigid cell walls. Both have nuclei to control the cell.

6. Which structure includes all of the others?

Answer: the nucleus.

The nucleus is the large dark spot in cells. Inside are the chromosomes (pieces of DNA) which contain genes (pieces of chromosomes which correspond to our traits), as well as nucleoli ( which are the sites of ribosome synthesis).

7. What is one function of the human endoskeleton?

Answer: produce blood cells.

Our skeletal system functions to support us and give us shape, to act as an attachment for muscles, for leverage for muscles to contract, and to produce blood cells in the marrow, or inside of certain bones. The nervous system transmits impulses, muscle cells produce lactic acid during strenuous workouts, and nitrogenous wastes are stored in the urinary bladder.

8. What does the presence of cilia, an oral groove, and food vacuoles, and the absence of chloroplasts in a unicellular organism indicate that the organism carries on?

Answer: heterotrophic nutrition.

Cilia are hair-like bristles on a Paramecium used in locomotion to find food. An oral groove is a mouth for a Paramecium, and food vacuoles store food in the cell body of the Paramecium. All of these are cell organelles used to ingest, digest, and egest preformed food, which is heterotrophic nutritrion. An autotroph can make its' own food using chloroplasts.

9. According to the heterotroph hypothesis, autotrophs were able to evolve because heterotrophs made conditions more favorable by doing what?

Answer: adding carbon dioxide to the environment.

Heterotrophs developed the ability to break down glucose, releasing the energy found within. In this process, carbon dioxide is released as a waste product. Autotrophs were able to use this waste gas in photosynthesis.

10. How does an organelle differ from an organ?

Answer: An organelle is a substructure of a cell.

From small to large, the order is organelle, cell, tissue, organ.
