Photosynthesis

Question 1

Where does photosynthesis happen

Answer 1

In chloroplasts which contain chlorophyll

Question 2

What does chlorophyll do

Answer 2

It absorbs light which transfers energy back to the chloroplasts

Question 3

Equation

Answer 3

Carbon dioxide + water ➡️ light➡️glucose + oxygen

6CO2 + 6H2O ➡️ C6 H12 O6 + 6O2

Question 4

What type of reaction is photosynthesis

Answer 4

Endothermic reaction meaning, it takes in energy during the reaction

Question 5

What is rate of photosynthesis affected by

Answer 5

The light intensity , concentration of CO2 , temperature

Question 6

What happens if the Temperature is the limiting factor

Answer 6

Its because the temperature is too LOW

The enzymes needed for photosynthesis work slowly

Question 7

What happens if the temperature is too hot

Answer 7

The enzymes needed for photosynthesis and other reactions become denatured

Happens at about 45 degrees

Question 8

What happens if carbon dioxide is increased

Answer 8

Increasing CO2 concentration increases the rate of photosynthesis up to a certain point then its no longer the limiting factor
