Photosynthesis and Respiration Quiz

Which life process carried out by a green plant is represented in the diagram below?

• Respiration

• Photosynthesis

• Digestion

• Replication

The diagram below represents a process that occurs in a structure of a specialized cell. Which answer correctly identifies the letters in the diagram?

• A - ribosome, B - oxygen, C - carbon dioxide, D - water

• A - mitochondrion, B - water, C - oxygen, D - protein

• A - nucleus, B - nitrogen, C - carbon, D - starch

• A - chloroplast, B - carbon dioxide, C - water, D - glucose

What process takes place in structure A?

• Heterotrophic nutrition

• Digestion of fats

• Cellular respiration

• Protein synthesis

During cellular respiration, what is the direct source of the energy used in the cells of consumers in the ecosystem represented below?

• Enzymes

• The Sun

• The atoms making up inorganic molecules

• The chemical bonds in organic molecules

Which dissolved substance do aquatic animals remove from their external environment for use in cellular respiration?

• Carbon dioxide

• Oxygen

• ATP

• Nitrogen molecules

During periods of vigorous physical activity, a person’s breathing and heart rates increase. This enables the cells of the body to perform more efficiently because it helps the cells to

• remove waste products faster

• reduce the amount of ATP produced

• store excess glucose in muscles

• convert more oxygen to glucose

Organisms contain compounds such as proteins, starches, and fats. The chemical bonds in these compounds can be a source of

• Amino acids

• Energy

• Simple sugars

• Enzymes

The most likely result of completely removing carbon dioxide from the environment of a plant is that sugar production will

• continue at the same rate

• increase and oxygen production will also increase

• increase and oxygen production will stay the same

• decrease and eventually stop

The setup below shows four test tubes. Tube 1 contains water only. Tube 2 contains a live snail. Tube 3 contains a live green water plant. Tube 4 contains both a live green water plant and a live snail. In this setup, which tubes contain at least one organism carrying on cellular respiration?

• Tubes 1 and 2, only

• Tubes 3 and 4, only

• Tubes 2 and 4, only

• Tubes 2, 3, and 4, only

The setup below shows four test tubes. Tube 1 contains water only. Tube 2 contains a live snail. Tube 3 contains a live green water plant. Tube 4 contains both a live green water plant and a live snail. Which compound that directly provides energy in living cells is being produced in every tube where cellular respiration is occurring?

• Oxygen

• DNA

• Glucose

• ATP
