Biology Quiz #3 Review

Animals get their energy either from plants or from eating other organisms. How do plants obtain their energy?

• They obtain their energy from the NUTRIENTS in the soil.

• They obtain their energy from the molecules in WATER (H₂0).

• They obtain their energy from the SUN in the form of radiant energy.

What is the name of the process that allows plants to produce their own food in the form of SUGAR (glucose)?

• Cellular Respiration

• Administrative Pause

• Photosynthesis

During the process of photosynthesis SUGAR (Glucose) is formed. The chemical formula is C₆H₁₂O₆. Where do the carbon atoms in SUGAR (glucose) come from?

• Water

• Coal

• Carbon Dioxide

Photosynthesis is defined as...

• The process that plants use to transform radiant energy into chemical energy (sugar/glucose).

• The process that most plants and some other organisms use to synthesize CO₂.

• The process that most animals and bacteria use to synthesize food and breathe.

A student conducting a lab to study photosynthesis. They are counting bubbles given off from an underwater leaf in bright sunlight at a temperature of 29°C. The bubbles would most likely be what type of molecule?

• Oxygen - O₂

• Carbon Dioxide - CO₂

• Sugar (glucose) - C₆H₁₂O₆

The student repeats this experiment but later at night in the dark (no sunlight). They continues to see bubbles. What would the most likely source of the bubble be?

• Oxygen - O₂

• Carbon Dioxide - CO₂

• Water - H₂0

Select all that are inputs for PHOTOSYNTHESIS? (select all that apply)

• Water

• Carbon Dioxide

• Oxygen

• Glucose (Sugar/food)

Which equation best represents CELLULAR RESPIRATION ?

• Sugar (glucose) + Oxygen ---> Water + Carbon Dioxide + ATP

• Oxygen + Water ---> Sugar (glucose) + Carbon Dioxide

In which way are PHOTOSYNTHESIS and CELLULAR RESPIRATION different?

• Cellular respiration stores ATP, while photosynthesis releases ATP.

• Cellular respiration produces oxygen as an INPUT, while photosynthesis uses oxygen as an OUTPUT.

• Photosynthesis uses carbon dioxide as a INPUT, while cellular respiration produces carbon dioxide as an OUTPUT.

What is the function of ATP in living things?

• Provides the type of energy our body uses to function

• Stores genetic information

• Provides structure in the nucleus
