The internal structure of the leaf is also adapted to promote efficient photosynthesis:

bubbles / time The internal structure of the leaf

While investigating these relationships, we might make two hypotheses. One is that the white leaves will be stunted because they contain less chlorophyll, which is needed for photosynthesis to occur. An alternative hypothesis is that the white leaves, or the white parts of leaves, will not be stunted because the leaves still contain a dense network of veins that can carry food from one part of the leaf to another, or from green leaves to white leaves.

Then, as photosynthesis and respiration occur you can find the net rate of photosynthesis occurring in a leaf over some time.

Luckily there are plants with variegated leaves

Here, we describe some simple ways of using variegated plants (e.g. variegated bhendi, Talipariti tiliaceum) to investigate the relationship between the presence of green pigment, food production and leaf growth.

Do the green regions of a variegated leaf exhibit more photosynthesis than white regions?

Variables: Independent variable: bicarbonate concentration

Dependent variable: number of disks floating after a minute

Control: amount of solution, size of leaf disks, amount of time cup is under light bulb, number of drops of liquid soap/ type of liquid soap The results suggest carbon dioxide concentration effects the rate of photosynthesis.

Cut a piece of black construction paper large enough to cover a broad leaf.
