KS3 / GCSE Biology: Photosynthesis Rap

Jon Chase:
Photosynthesis, it's just a chemical reaction and there are four things that we needfor it to happen. Water, CO2 and the light source and chlorophyll are relevantreactions of course.

Chlorophyll absorbs the energy and sunlight to combine water andcarbon dioxide, providing the glucose that the plants need, the byproducts oxygen weneed to breathe.

There needs to be light for the process to start, absorbed by thechlorophyll and chloroplasts, and of those, they can be found in all the green partsfor ossificis, mainly in the leaves of plants.

Now if you grab a leaf and take acloser look at it, you can check the way that it's perfectly adapted, like on thelower surface, the martyr are active in charge of the taking in and letting out ofgases.

The thin leaves help the oxygen and CO2 get straight to where it's needed,having less to journey through, and there are air spaces in between the cells too,giving larger surface area for gases to diffuse.

A transparent epidermis gives theleaf skin, with a large surface area for letting light in, and the chloroplasts aremainly in the upper leaf cells, while veins deliver water from the roots and stems.
