All organisms need glucose, or a source of energy to carry out basic life functions. Many plants obtain glucose through the process of photosynthesis . Animals obtain glucose from Photosynthesizing organisms use to produce glucose. 1. The reactants of photosynthesis are carbon dioxide and water The products of photosynthesis are glucose and oxygen The Sun is the source of energy used in photosynthesis.
The Correct Answer and Explanation is:
Correct Answer:
Photosynthesizing organisms use carbon dioxide, water, and energy from the Sun to produce glucose.
Explanation:
All living organisms require energy to carry out essential life functions such as growth, repair, movement, and reproduction. One of the most important sources of energy is glucose, a simple sugar that cells can easily break down to release energy. Plants, algae, and some bacteria produce glucose through a process called photosynthesis.
Photosynthesis is a chemical process where these organisms use sunlight as the energy source to convert carbon dioxide and water into glucose and oxygen. The general equation for photosynthesis is:
Carbon dioxide + Water + Sunlight → Glucose + Oxygen
In this process, carbon dioxide from the air enters the leaves of the plant through small openings called stomata. Water is absorbed by the roots from the soil and transported to the leaves through vessels called xylem. Inside the leaves, special structures known as chloroplasts contain a green pigment called chlorophyll. Chlorophyll captures energy from sunlight.
Using this energy, the plant converts carbon dioxide and water into glucose, which serves as an energy source for the plant’s cellular activities. Oxygen is produced as a byproduct and released into the atmosphere. This oxygen is essential for animals and humans, as it is used during respiration to release energy from the food they consume.
Animals, including humans, cannot perform photosynthesis. Instead, they obtain glucose by eating plants or by consuming other animals that have eaten plants. Therefore, photosynthesizing organisms form the base of the food chain by producing glucose, which stores energy in chemical bonds. This energy is then passed on to other organisms through feeding relationships, supporting life on Earth.
In conclusion, photosynthesizing organisms use carbon dioxide, water, and sunlight to produce glucose and oxygen, providing essential energy for themselves and for other living beings.
