Photosynthesis And Light Phase

Question 1

What is the chemical equation for photosynthesis

Answer 1

CO2+H2O——>{chlorophyll and enzymes) glucose +O2

Question 2

What are the 5 raw materials required for photosynthesis

Answer 2

CO2 from atmosphere
Water from soil
Radiant energy from sun
Chlorophyll (pigment) and chloroplast(organall) of green plants
Enzymes

Question 3

What are the products of photosynthesis

Answer 3

Glucose > stored in plant as starch
Oxygen >released into atmosphere

Question 4

Where does photosynthesis take place

Answer 4

In the chloroplast

Question 5

What 5 names are given to the different parts of a chloroplast?

Answer 5

Double membrain
Intergranum
Granum
Stroma
Lamella(thylakiod)

Question 6

What are the 2 processes of photosynthesis

Answer 6

Light phase> takes place in grana of chloroplasts in presents of light

Dark phase>takes place in stroma of chloroplasts in light or darkness

Question 7

Where does radiant energy from the sun get absorbed in the chloroplast

Answer 7

In the lamella(thykoids)

Question 8

Chemical energy is used for 2 processes in the light phase name them
And their process name

Answer 8

Water molecules are spit into ER hydrogen atoms(transferred to dark phase)and O2 is released into atmos

And is known as photolysis

Question 9

In Which phase is the ATP formed

Answer 9

In the Light phase

Question 10

Where does the dark phase/ Calvin cycle take place

Answer 10

Takes place in the stroma of chloroplast

Question 11

What are the 2 products of the dark phase

Answer 11

Energy rich carbohydrates (glucose) are formed
Excess glucose is converted into starch and stored
