Photosynthesis

Question 1

Plants

Answer 1

Plants use light, the reaction that plants use to trap this light energy is called photosynthesis
Because photosynthesis takes in energy it is an example of an endothermic reaction
Photosynthesis takes place in the leaves of a plant, leaves contain the green chemical chlorophyll which absorbs light energy

Question 2

What is the word equation for photosynthesis

Answer 2

carbon dioxide + water —————> glucose + oxygen
chlorophyll
. The plant takes carbon dioxide and water into the leaf
. Light energy is then absorbed by chlorophyll
. This light energy is used to convert carbon dioxide and water into sugar glucose and oxygen

Question 3

What is the symbol equation for Photosynthesis

Answer 3

CO2 + H2O —–> C6H12O6 + O2

Question 4

Light intensity (limiting factor)

Answer 4

. If we increase the light intensity and the rate of photosynthesis also increases, that tells us that the light intensity was limiting
. Meaning photosynthesis was not as fast as it could have been because there was not enough light
. At this point, light intensity was the limiting factor
. At some point there comes a point where if we increase light intensity, rate of photosynthesis doesn’t change meaning light intensity is no longer the limiting factor and something else is in short supply

Question 5

What are the factors that can affect photosynthesis

Answer 5

. Light intensity
. Chlorophyll in the leaf
. Carbon Dioxide levels
. Temperature

Question 6

What is photosynthesis

Answer 6

The reaction that plants use to trap light energy

Question 7

What type of reaction is photosynthesis

Answer 7

An endothermic reaction because it takes in light energy

Question 8

Where does photosynthesis take place in a plant

Answer 8

Photosynthesis takes place in the leaves of a plant, leaves contain the green chemical chlorophyll which absorbs light energy
