Slides Two: Photosynthesis Stores Energy in Organic Compounds

Question 1

What are the two chemical reactions of photosynthesis

Answer 1

Light independent and light dependant

Question 2

What are the products of light dependent

Answer 2

NADPH and ATP

Question 3

Pigments

Answer 3

Absorb certain wavelengths of light while reflecting others

Question 4

What is the main pigment in plants

Answer 4

Chlorophyll

Question 5

What is Beta Carotene

Answer 5

Converts Vit A to retinal (pigment our eyes can see)

Question 6

What does the correct wavelength and pigment do

Answer 6

Excites electrons

Question 7

When do we see colour

Answer 7

When electrons become less excited

Question 8

What does more absorbence =

Answer 8

More oxygen

Question 9

Light Dependant Reactions

Answer 9

Occour in the thylakoid membrane

Question 10

What is the process of light dependent reactions

Answer 10

Light energy is trapped by chlorophyll
Electrons get excited
Light energy split water and used electrons
Hydrogen is accepted by NADP
Oxygen released
Electron freed and go to other photosystem
