• H2O is water
• worded equation for photosynthesis is carbon dioxide + water sunlight over chlrophyll sugar over glucose + oxygen
• Photosynthesis takes place in chloroplasts which contain chlorophyll
• In photosynthesis plants take carbon dioxide from the air and release oxygen into the atmosphere.
• The process of photosynthesis can be represented using an equation.
• Glucose is used by plants as food, or stored as starch
• Respiration occurs in cells, specifically mitochondria
• Glucose and oxygen are produced by photosynthesis
• Plants use glucose to make cellulose (a type of carbohydrate) which forms their cells walls
• Cellulose gives plant tissues strength and rigidity
• During respiration glucose reacts with oxygen to produce water and energy (ATP)
• Cellular respiration is the breakdown of glucose molecules to release energy
• Light energy is absorbed by pigments such as chlorophyll
• Plants need light energy to carry out photosynthesis
• Starch is stored in specialised storage organs such as roots, tubers and seeds
• Photosynthetic pigments absorb light energy from sunlight
• Stomata are tiny openings on the underside of leaves that allow gases such as carbon dioxide and water vapour to enter and exit the leaf
• Chlorophyll is the most important pigment involved in photosynthesis
• Chloroplasts contain chlorophyll, which absorbs light energy from sunlight
• The light energy absorbed by chlorophyll is used to convert carbon dioxide into glucose during photosynthesis.
• The process of storing food involves converting sugar into starch using enzymes
• The light energy absorbed by chlorophyll is used to power chemical reactions that convert carbon dioxide into sugars
• Photosynthesis occurs in the mesophyll cells of leaves
• Photosynthesis takes place in the chloroplasts of green plants
• The process of photosynthesis takes place in the chloroplasts of plant cells
• During photosynthesis, plants absorb carbon dioxide from the air and release oxygen as a waste product
• Worded equation for photosynthesis is carbon dioxide + water sunlight over chlrophyll sugar over (glucose) + oxygen
• Chemical equation for photosynthesis is 6CO2 + 6H2O -> C6H12O6 + 6O2
• Conditons needed for photosynthesis are sunlight, chlrophyll, carbon dioxide and water


  Sunlight, Chlorophyll, carbon dioxide and water are needed for?
• What is photosynthesis?


  Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen Or food for the plants.
• During photosynthesis light energy is changed to?

  light energy is turned to chemical energy when photosynthesis is happening
• What is carbon dioxide?


  it is produced through the exchange of gases. This function is performed by the stomata
• Water is absorbed by the root of plants from the soil.
• Conditions necessary for Photosynthesis

  • " Sunlight"
  • "Chlorophyll"
  • "Carbon dioxide"
  • "water"
• Photosynthesis requires certain conditions
• Importance of Photosynthesis


  • It ensures that living things/living species have access to oxygen in the atmosphere
  • It keeps the environment or ecosystem's oxygen and carbon dioxide levels in check
  • Plants are the sources of fossil fuels
• Energy is locked in fuel as a result of photosynthesis
• Graphs


  • Easier to see trends in the data when it is displayed visually compared to when it is displayed numerically in a table
  • Complicated data can often be displayed and interpreted more easily in a graph format than in a data table
• Displaying data in graphs

  1. Easier to see trends

  2. Easier to interpret complicated data
• Graph


  A type of diagram that is used to represent recorded data or regular information
