- the 'leaf' -is- the place were food-stuffs are made for the trees growth,
and eventualy all the animal-life of the forest, and every-living thing!

photosynthesis: sugar from air, water, and sun.



the complex chemistry of photosynthesis goes on exclusivly in the small
area of the chloroplast like the one shown in the drawing. thosands of
thousands of chloroplat are found in the cells of a single leaf (p.102-103)
and within each chloroplast there are hundreds of layers of chlorophyll
(show in drawing) - drawing is here -

photosynthesis passes in the chloroplast by these steps:
- water pulled into the chloroplast from the plants roots come in contact
with the layers of chlorophyll.

- sunlight passes into the leaf strikes the chlorophyll, giving it the
(chemical?)energy to break the water apart. ( electrolosys ? h + o )

- the oxegen broken from the water is exhaled(released) by the leaf.
the hydrogen stays in the chloroplast -combined with a 'driver-molecule'
that has absorbed the excess energy.

- the energy-laden driver-molecule next cause the hydrogen to combine with
simple carbon compounds already built-up in the chloroplast by
carbon-dioxide taken from the air.

- with this last reaction, the change from light-energy to chemical-energy
is complete. -the complex, stable, energy-rich carbohydrate known as
'sugar' had been formed.
