Final answer:
Photosynthesis primarily involves light ('photo-') as plants combine ('synthesis') elements to create glucose and oxygen, which is crucial for life on Earth. so, option B is the correct answer.
Step-by-step explanation:
The word "photosynthesis" consists of two parts: "photo-" meaning light and "-synthesis" meaning putting together or combining. Thus, the Greek and Latin roots of the word "photosynthesis" indicate that it has to do with light (B), as it is the process by which plants use light to combine water and carbon dioxide to make glucose and oxygen. Photosynthesis is a crucial chemical reaction for life on Earth, as it not only creates glucose, which plants use as food, but also releases oxygen into the atmosphere, which is essential for animal and human respiration.
Photosynthesis is the process by which plants and bacteria convert carbon dioxide, water, and light energy into glucose and oxygen.
Photosynthesis is the process by which plants and bacteria convert carbon dioxide, water, and light energy into glucose (a carbohydrate) and oxygen. The word "photosynthesis" is derived from Greek roots, with "photo" meaning light and "synthesis" meaning to combine or create. Therefore, the correct answer is B. Light.
