This is called photosynthesis, which means "making through light".

The word equation for photosynthesis is: Light [IMAGE]Carbon Dioxide + Water Glucose + Oxygen Chlorophyll Although most of the glucose produced is converted into insoluble starch for storage in the stem, leaves or roots, some is used immediately by the plant to provide via respiration....

The aim was to show that light is necessary for photosynthesis.

Photosynthesis need light to work, so light therefore should speed up the rate of photosynthesis.

Action & Absorption Spectra in Photosynthesis | …

Prediction : I predict that as I increase the distance between the light source and the Canadian Pondweed (reducing the light intensity), the volume of oxygen produced within the time limit (the measure of the rate of photosynthesis) will decrease.

Light Direction, Absorption, and Photosynthesis | Plantae

Hypothesis:Photosynthesis is a process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose....

Photophosphorylation is the production of ATP using the energy of sunlight. Photophosphorylation is made possible as a result of chemiosmosis. Chemiosmosis is the movement of ions across a selectively permeable membrane, down their concentration gradient. During photosynthesis, light is absorbed by chlorophyll molecules. Electrons within these molecules are then raised to a higher energy state. These electrons then travel through Photosystem II, a chain of electron carriers and Photosystem I. As the electrons travel through the chain of electron carriers, they release energy. This energy is used to pump hydrogen ions across the thylakoid membrane and into the space within the thylakoid. A concentration gradient of hydrogen ions forms within this space. These then move back across the thylakoid membrane, down their concentration gradient through ATP synthase. ATP synthase uses the energy released from the movement of hydrogen ions down their concentration gradient to synthesise ATP from ADP and inorganic phosphate.

An absorption spectrum is a graph showing the percentage of light absorbed by pigments within the chloroplast, for each wavelength of light. An example is the absorption spectrum of chlorophyll a and b. The best absorption is seen with violet-blue light. There is also good absorption with red-orange light. However most of the green-yellow light is reflected and therefore not absorbed. This wavelength of light shows the least absorption.

the best absorption of light by chlorophyll is in ..

The light-independant reactions of photosynthesis occur in the stroma of the chloroplast and involve the conversion of carbon dioxide and other compounds into glucose. The light-independent reactions can be split into three stages, these are carbon fixation, the reduction reactions and finally the regeneration of ribulose bisphosphate. Collectively these stages are known as the Calvin Cycle.

Therefor, the faster the rate of photosynthesis, the faster the leaves rises.
There are five matters that affect the rate of photosynthesis: light intensity, temperature, CO2, water, and the color of light in general.

The action spectrum of photosynthesis is a graph showing the rate of photosynthesis for each wavelength of light. The rate of photosynthesis will not be the same for every wavelength of light. The rate of photosynthesis is the least with green-yellow light (525 nm-625 nm). Red-orange light (625nm-700nm) shows a good rate of photosynthesis however the best rate of photosynthesis is seen with violet-blue light (400nm-525nm).
