What are the roles of light, carbon dioxide, water, and chlorophyll in photosynthesis?
What are the roles of light, carbon dioxide, water, and chlorophyll in photosynthesis?
Light provides the energy needed for the process, carbon dioxide is used as a source of carbon, water is split to provide electrons and oxygen, and chlorophyll absorbs light to initiate the process.
What role does photosynthesis play in cycling materials and energy through ecosystems?
What role does photosynthesis play in cycling materials and energy through ecosystems?
Photosynthesis plays a vital role in cycling materials and energy through ecosystems by converting light energy into chemical energy stored in glucose, which is then used by organisms for growth, development, and energy.
What is the role of chloroplasts in photosynthesis?
What is the role of chloroplasts in photosynthesis?
Chloroplasts are green organelles that contain chlorophyll, which captures light energy to create oxygen and sugar by splitting water molecules into hydrogen and oxygen.

Study Notes
Photosynthesis Components
- Light is essential for photosynthesis, providing energy for the process.
- Carbon dioxide is a reactant in photosynthesis, used to produce glucose and oxygen.
- Water is a reactant in photosynthesis, used to produce glucose and oxygen.
- Chlorophyll is a green pigment that absorbs light energy for photosynthesis.
Photosynthesis in Ecosystems
- Photosynthesis plays a crucial role in cycling materials and energy through ecosystems, producing oxygen and organic compounds.
- It provides energy for plants to grow and develop, supporting the food chain.
Chloroplasts
- Chloroplasts are organelles found in plant cells, responsible for photosynthesis.
- They contain the pigment chlorophyll, which absorbs light energy for photosynthesis.
Photosynthesis Process
- The waste product released through stomata in the underside of the leaves during photosynthesis is oxygen.
- The substance formed after the reaction takes place in photosynthesis stage 2 is glucose (C6H12O6).
- The word equation for photosynthesis is: Carbon dioxide + Water + Light energy → Glucose + Oxygen.
- The chemical equation for photosynthesis is: 6CO2 + 6H2O + Light energy → C6H12O6 (glucose) + 6O2.
Plant Cells
- Cells break down glucose for energy, in plant cells, through cellular respiration.
- Plants store water in their cells, allowing them to act as natural flood control.
Oceanic Plants
- Oceanic plants absorb about 1-2% of the sun's energy to form oxygen through photosynthesis.
Carbon Dioxide
- Carbon dioxide enters the leaves during photosynthesis through the stomata.
Marsh Plants
- Marsh plants are important for energy absorption, playing a crucial role in the ecosystem.
