In the context of the carbon cycle, how do plants contribute to the process?
A
Plants release carbon dioxide into the atmosphere during photosynthesis.
B
Plants store carbon dioxide in the form of inorganic minerals.
C
Plants absorb carbon dioxide during photosynthesis and convert it into organic compounds.
D
Plants convert carbon dioxide into nitrogen compounds.
Verified step by step guidance1
Understand the role of plants in the carbon cycle: Plants are crucial in the carbon cycle as they help in the conversion of carbon dioxide (CO2) from the atmosphere into organic compounds.
Recognize the process of photosynthesis: During photosynthesis, plants absorb carbon dioxide from the atmosphere. This process occurs in the chloroplasts of plant cells.
Identify the chemical reaction involved: The general equation for photosynthesis can be represented as: . This shows the conversion of carbon dioxide and water into glucose and oxygen.
Clarify the storage of carbon: The glucose produced is used by the plant for energy and growth, and it can be stored as starch or used to build other organic compounds like cellulose.
Differentiate from incorrect statements: Plants do not release carbon dioxide during photosynthesis; instead, they release oxygen. They also do not convert carbon dioxide into nitrogen compounds or store it as inorganic minerals.
