That's whywe call it PHOTOsynthesis.

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....

we need water for photosynthesis).

This process is also affected by the temperature surrounding the plant (the species of plant we experimented with, pond weed, photosynthesised best at around 20 degrees centigrade.) Light, temperature & CO2 are known as limiting factors, and each is as important as the next in photosynthes...


Leaves contain chloroplasts, in which photosynthesis occurs.

Photosynthesis is conditioned by five main factors:

The net process of photosynthesis is described by the following equation: 6CO2 + 6H2O + Light Energy = C6H12O6 + 6O2 This equation simply means that carbon dioxide from the air and water combine in the presence of sunlight to form sugars, oxygen is released as a by-product of this reaction....


Write the number &name of the principle area of photosynthesis.

The first point, then, is that photons are absorbed by molecules when their electronic spectra have strong absorption bands around the frequency of the incoming photon, as the chlorophylls do. In the process of "absorption" of a photon, a molecule is "excited" to a state of higher energy because an electron has moved from a ground state molecular orbital energy level to a higher energy level. Only certain transitions can occur, however, because the frequency corresponding to the energy difference must match the frequency of the photon. This is a statement of the energy conservation law and can be written as , and the peaks that you see in the absorption spectrum of a molecule correspond to the possible energy level differences that allow absorption of photons of corresponding frequency.

Basic process of photosynthesis

The first step in photosynthesis is the interaction of light with chlorophyll molecules. The chemical structures of the various chlorophyll molecules are based upon the cyclic tetrapyrrole that is also seen in the heme group of globins and cytochromes. Various modifications of this group, namely ring saturation characteristics and substitutions on the rings provide a series of pigment molecules that, as a group, absorb effectively over the wavelength range of 400 nm - 700 nm, the spectrum of . It is the high degree of conjugation of these molecules that makes them so efficient as absorbers of visible light.

The raw materials neededfor photosynthesis include ...

A molecule in an excited electronic state must dissipate the extra energy in some way, and we can talk about different modes of "decay" of that energy to a lower electronic state (which does not necessarily have to be the ground state). There are three types of dissipation that can occur: "non-radiative," "radiative," and chemical reaction.

All chemical pathways in photosynthesis are controlled by enzymes.

While photosynthesis is performed by most plants which can prepare their own food, most animals fulfill their energy requirements through cellular respiration.

Photosynthesis is the process by which plant cells convert light energy from the sun into chemical energy, so as to create energy-rich carbohydrate molecules like glucose.
