Here's a taster:

What are they?
Chloroplasts are found the
photosynthetic cell region of green
plants and algae. They are bound
by a double membrane and have
organelles are so are eukaryotic
cells. These are found in the
palisade cells of a leaf.…read more

Here's a taster:

Parts of the Chloroplast
O Thylakoid membrane = A system of
interconnected flattened, fluid-filled sacs. Have a
number of small molecules in them like proteins
including photosynthetic pigments (make the
leaf green) and electron carriers which help in
the light dependant stages
O Stroma = the fluid surrounding the thylakoid
membranes. Contains all the enzymes needed to
carry out the light- independent reactions of
photosynthesis.…read more

Here's a taster:

O Thylakoid Space = the
fluid within the
thylakoid membrance
sacs which contain
enzymes for photolysis
(the splitting of water
using light energy to
give oxygen, hydrogen
ions and electrons. The
hydrogen ions are used
in the light-dependant
O Granum = a stack of
thylakoids joined to
one another. Grana
(plural) resemble
stacks of coins.…read more
