Photosynthesis and Respiration- Easy

What are the chemical reactants required for photosynthesis to occur?

• Oxygen and nitrogen

• Methane and sulfur dioxide

• Carbon dioxide and water

• Hydrogen and helium

Answer explanation

Photosynthesis requires carbon dioxide and water as the chemical reactants. These reactants are used by plants to produce glucose and oxygen through the process of photosynthesis.

Explain the role of chlorophyll in the process of photosynthesis.

• Chlorophyll helps in the production of glucose in the mitochondria

• Chlorophyll releases oxygen into the atmosphere

• Chlorophyll absorbs light energy and converts it into chemical energy.

• Chlorophyll absorbs carbon dioxide from the environment

Answer explanation

Chlorophyll absorbs light energy and converts it into chemical energy, playing a crucial role in photosynthesis.

How does the process of photosynthesis contribute to the oxygen levels in the atmosphere?

• Photosynthesis produces oxygen as a byproduct

• Photosynthesis produces carbon dioxide as a byproduct

• Photosynthesis has no impact on oxygen levels

• Photosynthesis consumes oxygen from the atmosphere

Answer explanation

Photosynthesis produces oxygen as a byproduct, contributing to higher oxygen levels in the atmosphere.

What is the primary goal of cellular respiration?

• Create sunlight

• Convert glucose to water

• Produce ATP

• Produce carbon dioxide

Answer explanation

The primary goal of cellular respiration is to produce ATP, which is the correct choice.

Explain the role of mitochondria in cellular respiration.

• Mitochondria produce glucose during cellular respiration.

• Mitochondria produce ATP during cellular respiration.

• Mitochondria store water during cellular respiration.

• Mitochondria break down carbon dioxide during cellular respiration

Answer explanation

Mitochondria play a crucial role in cellular respiration by producing ATP, the energy currency of the cell.
