The document presents information about photosynthesis. It defines photosynthesis as the process by which plants use sunlight, carbon dioxide, and water to produce food (glucose) and oxygen. The key requirements for photosynthesis are explained as water, carbon dioxide, light energy from the sun, and chlorophyll. The document also notes that photosynthesis occurs within chloroplasts in the leaves of plants and describes the basic photosynthesis equation and products.

2. What is photosynthesis?
• Is the process in which plants make their own food
How?
• through the process by which the chlorophyll in the leaves of plants capture light
energy which they then use to change carbon dioxide and water into food.This
plant food is called glucose.

3. What is needed for
photosynthesis to take place
• These are the things a plant needs for
photosynthesis:
• 1. water
• 2. carbon dioxide
• 3. light energy from the Sun
• In addition to water and carbon dioxide,
photosynthesis requires light and chlorophyll.

5. The process :
• Photosynthesis is the process by which green plants use sunlight to
manufacture food from simple molecules like CO₂ (carbon dioxide) and H₂O(
water).
• autotrophic organisms (organisms that make their own food, e.g.plants) use light
energy to make sugar and oxygen gas from carbon dioxide and water.
Occurs in plants, algae and some prokaryotes.
• Anabolic (small molecules combined) & Endergonic (stores energy)
• Photosynthesis is sometimes called carbon assimilation and is
• represented by following equation

6. • Photosynthesis can be presented in an equation:

7. Where does photosynthesis take place?
• Photosynthesis takes place inside chloroplasts

8. • Chloroplasts contain thylakoids— saclike photosynthetic membranes.
• Thylakoids are arranged in stacks known as grana. A singular stack is called a
granum.
• Proteins in the thylakoid membrane organize chlorophyll and other pigments into
clusters called photosystems, which are the light-collecting units of the
chloroplast.
