photosynthesis Flashcards
What is photosynthesis?
Photosynthesis is the process where plants take carbon dioxide from the air, water from the ground, and energy from the sun to produce glucose (food for the plant) through chemical reactions.
Carbon dioxide enters and exits as oxygen through a leaf’s stomata.
What is the chemical equation for photosynthesis?
The chemical equation for photosynthesis is: CO2 + H2O -> C6H12O6 + O2.
O2 is a byproduct.
What are the steps in the process of photosynthesis?
- Light energy from the sun contacts the green parts of the plant. 2. Chlorophyll absorbs the light energy. 3. The light energy binds CO2 with water. 4. Food molecules like glucose are formed. 5. Oxygen is released as a byproduct.
What is glucose used for in plants?
Glucose is a source of energy for all living things. It is converted to starch and cellulose and stored in different regions of the plant, such as sweet potatoes, white potatoes, purple potatoes, corn, pumpkin, and squash.
What is the importance of photosynthesis?
Photosynthesis allows plants to self-feed, releases oxygen, absorbs CO2 from the atmosphere, and fuels from fossilized carbon.
What is a chloroplast?
A chloroplast is the organelle in a plant cell that contains chlorophyll.
What is chlorophyll?
Chlorophyll is the green substance in plant cells that traps radiant energy.
What factors affect photosynthesis?
Factors that affect photosynthesis include temperature, light intensity, CO2 concentration, water content of the soil, and mineral content of the soil.
