Here's a taster:

If certain things are in short supply, they may limit the amount of
photosynthesis a plant can manage.
Light:
If there is plenty of light, then lots
of photosynthesis can take place. If
there is little or no light,
photosynthesis will stop regardless
of the other conditions.
At the start the rate of P. increase
as the light intensity increases.
But then we reach a point where no
matter what the light intensity is,
the rate stays the same.…read more

How Plants Use Glucose:
The energy released in respiration is used to build up smaller
molecules into bigger molecules.
They build up sugar into more complex carbohydrates like
cellulose which is used to make cell walls
They combine sugars with nutrients in the soil to make
amino acids, which are built up to make proteins to be used
in cells.
They build up fats and oils to make a food store in seeds.…read more

Here's a taster:

Plants need more than Carbon Dioxide, Water and Light to thrive.
They also need mineral salts from the soil to make chemicals for
their cells.
Nitrates:
The problem with the products of photosynthesis is that they are
all carbohydrates. Plants also need proteins to act as enzymes
and make up a large part of the cytoplasm and the membranes.
Proteins contain Hydrogen, Oxygen, Carbon and Nitrogen. The first
three they can get from glucose and starch.…read more

Swallowtail

A very clear and concise set of notes covering the key areas of photosynthesis and plant transport.  The diagrams and graphs are in colour with key words highlighted. These topic areas are found in most GCSE science syllabuses.

Students could try redrawing the diagrams from memory and add the labels, or summarise the information in a mind map with pictures and colours separating each idea.
