B8 - Photosynthesis Flashcards
Is photosynthesis endothermic or exothermic
Endothermic
What is the equation for photosynthesis
Carbon dioxide + water = glucose + oxygen
Where does photosynthesis occur in the cells
In the chloroplasts
What is photosynthesis
Process where green plants and other organisms use sunlight to synthesise glucose from carbon dioxide and water
What is the pigment called in chloroplasts that absorbs light
Chlorophyll
Name adaptations of leaves for more effective photosynthesis
Broad or thinner leaves, air pockets or guard cells to regulate the stomata opening
Name the limiting factors of photosynthesis
Light, carbon dioxide concerntration, temperature and chlorophyll levels
Name a use of glucose in plants
Respiration, makes or strengthens cullulose wall, makes starch for storage and lipids as an energy store
Why do plants need nitrates for growth
To make proteins
Why would photosynthesis rates decrease at a higher temperature
Enzymes become denatured
