5.2.1 (b,c) the Chloroplast

Question 1

what are organisms which photosynthesise called?

Answer 1

autotrophs

Question 2

what is the equation for photosynthesis?

Answer 2

6CO2 + 6H20 -> C6H12O6 + 602

Question 3

adaptations of chloroplast?

Answer 3

network of membranes provides a large surface area which allows for maximum sunlight absorption

Answer 4

outer membrane
inner membrane
thylakoid
granum
stroma

Question 5

what are a stack of thylakoids called?

Answer 5

grana

Question 6

what are grana joined together by?

Answer 6

lamallae

Question 7

what is the fluid in a chloroplast?

Answer 7

stroma

Question 8

what happens in the stroma?

Answer 8

chemical reactions to form complex molecules

Question 9

what is the primary pigment in photosynthesis?

Answer 9

chlorophyll

Question 10

what do pigment molecules do?

Answer 10

absorbs certain wavelengths of light and reflect others

Question 11

what is a photosystem?

Answer 11

a light harvesting system and a reaction centre

the protein and pigment

reaction centre = primary pigment
light harvesting system = accessory pigments
