Photosynthesis and Respiration Concepts

The video explains the constant exchange of Oxygen and Carbon Dioxide between plants and animals. Oxygen, produced by plants during photosynthesis, is essential for animal survival, while animals exhale Carbon Dioxide, which plants use. This exchange forms the Oxygen-Carbon Dioxide cycle. The video highlights the importance of Oxygen for humans and Carbon Dioxide for plants, emphasizing their essential roles in survival.

What process in plants is responsible for the production of oxygen?

• Respiration

• Photosynthesis

• Transpiration

• Fermentation

During respiration, what do animals exhale?

• Nitrogen

• Carbon Dioxide

• Hydrogen

• Oxygen

What is the role of carbon dioxide in the oxygen-carbon dioxide cycle?

• It is inhaled by animals during respiration

• It is taken in by plants and released as oxygen

• It is a byproduct of water evaporation

• It is produced by plants during photosynthesis

Why is oxygen more crucial for humans compared to water and food?

• It is essential for respiration

• It is needed for photosynthesis

• It helps in digestion

• It is used in fermentation

Why is carbon dioxide important for plants?

• It is used in respiration

• It is essential for photosynthesis

• It is a source of energy

• It helps in water absorption
