Chloroplasts Flashcards
Where are chloroplasts found?
In plant cells that carry out photosynthesis
What 2 reactions can photosynthesis be?
Light dependent reactions and light intensive reactions
What is the stroma?
The fluid where LIR’s take place
What does the stroma contain?
Enzymes needed for these reactions
What does the membrane do?
Controls what molecules enter and exit the chloroplast
What do the ribosomes in the chloroplasts do?
Synthesise the proteins encoded by the chloroplast DNA
What are thylakoids?
Membrane-bound flattened discs where the LDR reaction takes place
What do thylakoids contain?
Chloroplasts and enzymes
What is the geranium?
A stack of thylakoids so that light can be absorbed more easily
What is chloroplast DNA?
A loop of DNA which contains genes which encode some of the proteins needed for photosynthesis
What is a starch granule?
Glucose (a product of photosynthesis) is stored after being converted into starch
What are lamellae?
Flattened membranes which connect grana and play a role in LDR by allowing chemicals to pass between grana and
