Respiration releases Carbon Dioxide

Respiration
Respiration is a process where living cells utilize oxygen to release energy from food. It occurs in both plants and animals. Respiration can be of two types: aerobic and anaerobic. In aerobic respiration, oxygen is used while in anaerobic respiration, oxygen is not used.

Carbon Dioxide Release
During the process of respiration, glucose is oxidized to release energy, carbon dioxide, and water. The chemical equation is:

C6H12O6 + 6O2 → 6CO2 + 6H2O + energy

Carbon dioxide is produced as a byproduct of respiration and is released into the atmosphere.

Photosynthesis
Photosynthesis is a process where plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. The chemical equation for photosynthesis is:

6CO2 + 6H2O + sunlight → C6H12O6 + 6O2

During photosynthesis, carbon dioxide is taken in from the atmosphere and is used to produce glucose. Oxygen is released as a byproduct.

Transpiration and Ascent of Sap
Transpiration is a process where water is lost from the leaves of plants through small openings called stomata. Ascent of sap is the upward movement of sap in plants, which is driven by transpiration. Neither of these processes releases carbon dioxide.

Therefore, the correct answer to the question is option B, respiration releases carbon dioxide.

In respiration in plants, Co2 is utilised and oxygen is liberated. and the oxygen is utilised in respiration of humans and carbon dioxide will be liberated
So, Oxygen is liberated during photosynthesis
Carbon dioxide is liberated during respiration
