Lesson Worksheet: Respiration in Plants Biology

In this worksheet, we will practice describing the process of respiration in a plant and discussing the relationship between respiration and photosynthesis.

Q1:

What are the reactants required for aerobic respiration in plants?

  • AOxygen and water
  • BCarbon dioxide and water
  • CCarbon dioxide and glucose
  • DOxygen and glucose
  • EGlucose and water

Q2:

Plants require oxygen to carry out aerobic respiration. Which of the following is not a method by which plants obtain this oxygen?

  • AOxygen produced by the plant during photosynthesis is used in respiration.
  • BOxygen is dissolved into water and enters the roots of the plant.
  • COxygen diffuses into the leaf through stomata.
  • DOxygen is breathed in by the plant through open airways in the leaf.

Q3:

Which of the following gases is produced by aerobic respiration?

  • ACarbon monoxide
  • BSulphur dioxide
  • COxygen
  • DHydrogen
  • ECarbon dioxide

Q4:

Plants require glucose to carry out respiration. By what method do they obtain the majority of this glucose?

  • AGlucose is produced during transpiration.
  • BGlucose is actively transported from the soil and into the roots.
  • CGlucose is produced during photosynthesis.
  • DGlucose diffuses into the leaf via the open stomata.

Q5:

In what cellular organelle does aerobic respiration take place in a plant?

  • AMitochondria
  • BCell membrane
  • CNucleus
  • DChloroplast

Q6:

Glucose is a product of photosynthesis. How can this glucose be used by plants?

  • AAs a reactant in respiration
  • BAs a storage molecule
  • CAs structural support for plant cell walls
  • DAs a source of nitrates

Q7:

The diagram provided shows an experiment set up to investigate respiration in plants. A plant and a vial of limewater are placed inside a large, upturned jar. In the presence of carbon dioxide, limewater turns from clear to cloudy.

The bell jar is covered with a thick, black sheet and left for 24 hours.

What would you expect to happen to the limewater?

  • ATo turn cloudy
  • BTo remain clear

Why would you expect to see this result?

  • AThe plant will respire but not photosynthesize, so there will be carbon dioxide present.
  • BThe plant will be respiring and releasing CO2 but also photosynthesizing and absorbing it.

Q8:

The diagram provided shows an experiment set up to investigate respiration in plants. A plant and a vial of limewater are placed inside a large, upturned jar. In the presence of carbon dioxide, limewater turns from clear to cloudy.

The lamp is turned on, and the plant is left for 24 hours.

What would you expect to happen to the limewater?

  • AIt would turn cloudy.
  • BIt would remain clear.

Why would you expect to see this result?

  • AThe plant would respire but not photosynthesize, so there would be carbon dioxide present.
  • BThe plant would be respiring and releasing CO2, but also photosynthesising and absorbing it.

What molecule would correctly replace label 1?

  • ACarbon dioxide
  • BWater
  • COxygen
  • DHydrogen

What molecule would correctly replace label 2?

  • ACarbon dioxide
  • BGlucose
  • CHydrogen
  • DOxygen

Q10:

A diagram linking the processes of photosynthesis and respiration in plants is provided, with two key molecules removed.

What molecule would correctly replace label 1?

  • AGlucose
  • BWater
  • CCarbon dioxide
  • DHydrogen

What molecule would correctly replace label 2?

  • AWater
  • BGlucose
  • COxygen
  • DHydrogen
