The gasses is important to photosynthesis is d. carbon dioxide. Therefore , d. carbon dioxide is correct .
The gas essential to photosynthesis is d. carbon dioxide.
Photosynthesis is a crucial biological process that occurs in plants, algae, and some bacteria, enabling them to convert light energy into chemical energy in the form of glucose.
During photosynthesis, carbon dioxide is taken in from the atmosphere through tiny pores in the leaves called stomata.
The process involves the absorption of sunlight by chlorophyll, a green pigment in plant cells.
Carbon dioxide, along with water absorbed through the plant's roots, undergoes a series of chemical reactions to produce glucose and oxygen as byproducts.
This reaction can be summarized as:
6 CO2 + 6 H2O + light energy → C6H12O6 (glucose) + 6 O2
This equation demonstrates that carbon dioxide is a crucial component of photosynthesis, serving as a source of carbon that is incorporated into glucose.
Oxygen is released as a byproduct and is subsequently released into the atmosphere, contributing to the oxygen cycle.
Therefore, option d. carbon dioxide is the correct answer, as it plays a central role in the photosynthetic process that sustains life in the ecosystem.
Options a. ozone gas, b. water vapor, and c. oxygen, while important in their own right, do not serve as the primary source of carbon for photosynthesis.
