Step-by-step solution for: Plants and Photosynthesis STEM
The image provided is a visual representation of the process of photosynthesis in plants. Photosynthesis is the process by which plants, algae, and some bacteria convert light energy (from the sun) into chemical energy stored in glucose (sugar). This process is crucial for life on Earth as it produces oxygen, which is essential for most living organisms.
1. Sunlight: The primary energy source for photosynthesis.
2. Carbon Dioxide (CO₂): Absorbed from the atmosphere through small openings in leaves called stomata.
3. Water (H₂O): Absorbed by the plant's roots from the soil.
4. Chlorophyll: A green pigment in the chloroplasts of plant cells that captures sunlight.
5. Oxygen (O₂): Released as a byproduct of photosynthesis into the atmosphere.
6. Sugars (Glucose): Produced during photosynthesis and used by the plant for energy and growth.
The diagram illustrates how these components interact during photosynthesis:
1. Absorption of Sunlight: Sunlight is absorbed by chlorophyll in the leaves of the plant.
2. Absorption of Carbon Dioxide: CO₂ enters the plant through stomata in the leaves.
3. Absorption of Water: H₂O is taken up by the roots from the soil and transported to the leaves.
4. Conversion: Using the energy from sunlight, the plant converts CO₂ and H₂O into glucose (a sugar) and oxygen.
5. Release of Oxygen: O₂ is released into the atmosphere as a byproduct.
6. Storage of Sugars: Glucose is used by the plant for energy or stored as starch for later use.
The overall chemical equation for photosynthesis can be summarized as:
\[
6 \text{CO}_2 + 6 \text{H}_2\text{O} + \text{Light Energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2
\]
- Reactants: Carbon dioxide (CO₂), water (H₂O), and light energy.
- Products: Glucose (C₆H₁₂O₆) and oxygen (O₂).
- Sunlight: Arrows indicate that sunlight is absorbed by the plant.
- Carbon Dioxide (CO₂): Represented as coming from the air and entering the plant.
- Water (H₂O): Shown as being absorbed by the roots from the soil.
- Oxygen (O₂): Indicated as being released into the atmosphere.
- Sugars: Represented as the end product of photosynthesis, used by the plant for energy and growth.
The diagram illustrates the process of photosynthesis, where plants use sunlight, carbon dioxide, and water to produce glucose (sugars) and release oxygen as a byproduct. This process is fundamental for plant growth and survival and plays a critical role in maintaining the balance of gases in Earth's atmosphere.
