Photosynthesis
- A typical plant takes in carbon dixoide and water and uses these to make sugars and other complexes substances. Oxygen is
released as a waste product. This reaction is endergonic and requires an external source of free energy. This energy i supplied by
sunlight that falls on the plant. a green substance, chlorophyll, enables the plant to trap light energy and use it to make sugars. this is
the process known as photosynthesis
- Photosynthesis equation;
6CO2+12H2O=C6H12O6+6O2+6H2O
- Converting glucose to other substances; the glucose
formed by photosynthesis is used as a raw material
for other chemical reactions. it is the main substrate
used in respiration. Some of the glucose is converted
to other carbohydrates; cellulose to form cell walls,
sucrose to be transported to other parts of the plant,
and starch for storage
- The site of photosynthesis; although leaves are the main sites of
photosynthesis in most plants, it can take place in any part that is green. These
green parts have chloroplasts which contain all the biochemical machienery
necessary for photosynthesis. The light-dependant stage takes place in the
grana of the chloroplast, while the light-independant stage occurs in the stroma
