Final answer:
Photosynthesis is a vital process in biology where plants and bacteria convert carbon dioxide, water, and light into glucose and oxygen. It occurs mainly in the leaves of plants, specifically in the mesophyll layer where gas exchange takes place through stomata.
Step-by-step explanation:
Photosynthesis is a vital process in biology where plants and bacteria convert carbon dioxide, water, and light into glucose and oxygen. During photosynthesis, carbon dioxide and water combine with solar energy to create glucose and release oxygen. This process occurs mainly in the leaves of plants, specifically in the mesophyll layer where gas exchange of carbon dioxide and oxygen takes place through stomata.
The substrates of photosynthesis are carbon dioxide, water, and sunlight, while the products are glucose and oxygen. Photosynthesis is essential for the existence of life on Earth as it provides energy and oxygen for all living organisms.
