These gaps are filled with gas that the plant uses (carbon dioxide - CO ) and gases that the plant is expelling (oxygen - O, and water vapor).
- the angle between the upper side of the stem and a leaf or petiole.
- a molecule in leaves that can use light energy from sunlight to turn water and carbon dioxide gas into sugar and oxygen (this process is called photosynthesis).

 Evaluation: For my experiment, I had to find out whether light affects the rate of photosynthesis.



Factors that affect photosynthesis

If a plant gets more light, carbon dioxide, water or a higher
temperature, then it might be able to photosynthesise at a faster
rate.

However, the rate of photosynthesis will eventually reach a
maximum because there is not enough of one of the factors needed, one
of them becomes a limiting factors.

Prediction: I predict that as the light source (desk lamp) is moved closer to the pondweed (Elodea), the rate of photosynthesis will increase therefore more oxygen will be produced creating more bubbles.

Prediction:

I predicted that the smaller the distance between the plant and the
sauce of light, the greater would be the rate of photosynthesis.

Therefore the closer the light source is to the plant,
the greater will be the intensity of the light and so the chlorophyll
within the plant will be able to photosynthesise at a faster rate.

In leaf …plant stem by a stalklike petiole

The existence of light is esational
for this process, as the following equation shows:

LIGHT

CHLOROPHYLL

The role of light within photosynthesis is too absorbed by
chlorophyll.

Therefore, the more
the light that is available to the green plant, the greater will be
the rate of photosynthesis and so more glucose and oxygen will be
formed.

Hydrogen derived from water (H2O) also is incorporated into organic compounds in the photosynthetic process. Hydrogen ions are involved in electrochemical reactions and maintain electrical charge balances across all membranes.
