Mitochondria Provide the Main Source of Cytosolic ATP …
Photosynthesis usuallyoccurs in parenchyma cells (the mesophyll), and they function in thestorage ofcarbohydrates.
thylakoid membranes and function in the proton pumps of ATP synthesis
Specialised cells called guard cells control the openingand closing of these stomata, regulating the exchange ofgases andwater vapour between the outside air and the interior of the leaf.
If you make a wetmount of a leaf from the pondweed ,you may be able to see the cell'sorganelles, especially the , movingas the cytoplasm flows through the cell (Raven 2005)
Mesophyll chloroplastisds; Plant cell with plastids-www ..
Thus the reactions of the light-dependent stage of photosynthesis
provide a source of reducing power (NADPH) and the universal
energy-supplying molecule ATP, with oxygen gas given off as a waste
As increase in temperature or air
movement decreases relative humidity and causes guard cells in the
leaf to shrink, opening the stomata and increasing the rate of
The key enzymes of starch synthesis are absent in mesophyll cells.
Carbon dioxide is trapped and reduced to carbohydrate in the
light-independent reactions of photosynthesis, using ATP and reduced
NADP from the light-dependent reactions.
During these reactions the photosynthetic pigments of the chloroplast
absorb light energy and give out excited electrons used to synthesise
Chloroplasts are found mainly in cells of mesophyll, ..

are equipped with many leaves that have many mesophyll cells, which in turn have many chloroplasts;

If this happens a carrier molecule will pick
up the excited electron, and this can result in the synthesis of ATP
by one of two processes - cyclic or non-cyclic photophosphorolation.
