What are chloroplasts?
Small, flattened organelles found in plant cells
1 of 7
Double or single membrane?
Double - chloroplast envelope
2 of 7
What are Thylakoids?
Fliud filled sacs which are found in the chloroplast and are stacked up into structures called grana. - Grana are linked together by bits of thylakoid membrane called lamellae
3 of 7
What are photosynthetic pigments and which ones can be found in the chloroplast?
Coloured substances that absorb light energy needed for photosynthesis - chlorophyll a, chlorophyll b and carotene
4 of 7
Where in the chloroplast are photosynthetice pigments found?
In the thylakoid membranes - they're attached to protiens to form a photosystem
5 of 7
What wave legnth of light is best absorbed by each photosystem in the chloroplast?
photosystem I 700nm, photosystem II 680nm
6 of 7
What is the stroma?
A gel-like substance contained within the inner membrane of the chloroplasts and surrounding the thylakoids. It contains enzymes, sugars, organic acids and oil droplets.
