What is the word equation for photosynthesis? | Carbon Dioxide + Water = Glucose + Oxygen |
What is the process for photosynthesis? | 1. CO2 is taken in by the leaves & water is taken in by the roots. 2. Chlorophyll traps light energy needed for photsynthesis 3. Energy is used to convert CO2 and water into glucose |
Name three limiting factors of photsythesis | Lack of light, Coldness/Temperature, Lack of carbon dioxide |
Name 5 ways that plants use glucose | Converted into insoluble starch for storage, Respiration, Converted into fats and oils for storage, To produce cellulose (to strengthen cell walls), To produce proteins |
Name 6 physical factors which may affect the distribution of organisms | Temperature, Availability of nutrients, Amount of light, Availability of water, Availability of oxygen, Availability of carbon dioxide |
Name two types of obtaining quantitative data | Random quantitative sampling using a quadrat Sampling along a transect |
