B8(Photosynthesis) Flashcards
What kind of reaction is photosynthesis
Endothermic
What is the word equation for photosynthesis
Carbon dioxide + water ——> glucose + oxygen
What is the symbol equation for photosynthesis
6CO2 + 6H2O ——-> C6 H12 O6 + 6O2
What are the limiting factors that affect the rate of photosynthesis
-Light intensity
-Temperature
-CO2 concentration
-Chlorophyll concentration in the leaf
What is the inverse square law
Light intensity= 1/d^2
-D is the distance
Distance= 1/√light intensity
How do plants use glucose
-Used for respiration
-To convert into insoluble starch for storage
-to produce fats or oils for storage
-To produce cellulose to strengthen cell walls
-To produce amino acids for protein synthesis
How is starch used in plants
Starch is turned back into glucose when needed for example at night
What enzyme turns starch back into glucose
Amylase
Why do plants convert glucose into starch
Because glucose is soluble which means it cannot be stored in the plant and starch is insoluble which means it can be stored in the plant
How do plants make amino acids
combining glucose with nitrate ions makes amino acids for plants
