B8(Photosynthesis)

Question 1

What kind of reaction is photosynthesis

Answer 1

Endothermic

Question 2

What is the word equation for photosynthesis

Answer 2

Carbon dioxide + water ——> glucose + oxygen

Question 3

What is the symbol equation for photosynthesis

Answer 3

6CO2 + 6H2O ——-> C6 H12 O6 + 6O2

Question 4

What are the limiting factors that affect the rate of photosynthesis

Answer 4

-Light intensity
-Temperature
-CO2 concentration
-Chlorophyll concentration in the leaf

Question 5

What is the inverse square law

Answer 5

Light intensity= 1/d^2
-D is the distance

Distance= 1/√light intensity

Question 6

How do plants use glucose

Answer 6

-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

Question 7

How is starch used in plants

Answer 7

Starch is turned back into glucose when needed for example at night

Question 8

What enzyme turns starch back into glucose

Answer 8

Amylase

Question 9

Why do plants convert glucose into starch

Answer 9

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

Question 10

How do plants make amino acids

Answer 10

combining glucose with nitrate ions makes amino acids for plants
