(7, 6) 5. ... provides energy for photosynthesis. An increase in ... means an increased rate of photosynthesis until a point. After certain point, temperature or carbon dioxide will be limiting factor (5) 8. This uses energy to change carbon dioxide and water into glucose and oxygen. It takes place in chloroplasts in green plant cells, which contain pigments called chlorophyll that absorb light. It is endothermic (14) Down 2. As distance increases, light intensity decreases. so they are ... proportional. Light Intensity = 1/distance squared. Double distance= Intensity 4x smaller. Half distance= Light intensity 4x bigger (9) 3. Plants use ... for: 1) Respiration 2) Making cellulose -makes strong plant walls 3) Making Amino Acids- ... combined with nitrate ions 4)Stored as oils or fats- turned into lipids for storing seeds 5) Stored as starch- stored in roots (7) 4. ... is the raw material needed for photosynthesis. It only increases the rate of photosynthesis to a certain extent. With enough light and ...- Temperature must be limiting factor (6, 7) 6. ... of photosynthesis are light, concentration of carbon dioxide and temperature. A ... stops it from happening faster. Chlorophyll can also be a ... which is affected by disease or environmental stress. (8, 7) 7. Enzymes needed work slower at lower ... If a plant is too hot, enzymes will be damaged/denatured which happens at around 45 degrees (11)
