Chloroplasts Flashcards
(12 cards)
What figures should you be able to identify on a chloroplast?
Granum (stacks of thylakoids), thylakoid membranes, stroma (containing 70S ribosomes and NAKED DNA), lipid droplets, starch grain, and the inner and out membranes of the chloroplast envelope.
What two parts make up the chloropast envelope?
The inner and outermembranes.
Where do the light independent reactions occur?
In the stroma.
Where do the light dependent reactions occur?
In the thylakoid membrane.
What is the mesophyll?
The tissue in the interior of the leaf where chloroplasts are regularly found.
What are the stomata?
(Stoma) They assist CO2 in entering the leaf and O2 exiting.
What is stroma?
The dense fluid within the chloroplast.
What are thylakoids?
The system of interconnected membranous sacs
What are grana/granum?
The stacks of thylakoids.
Where does chlorophyll reside?
In the thylakoid membranes.
What do mesophylls contain?
Chloroplasts and stroma.
Explain the relationship between the structure of the chloroplast and its function.
The grana are stacked on top of each other to create more surface area for electron transport within the chloroplast cell.
