More key facts for GCSE Photosynthesis
Learning about photosynthesis will help you succeed in your GCSE Biology exam. There is lots to learn about photosynthesis, but if you break it down into the key facts, it is much more manageable and easy to remember. Check out our first blog on the key facts of photosynthesis by clicking here.
There is more to know so let’s take a look.
Parts of the leaf which are involved in the process of photosynthesis:
The upper epidermis - allows light to reach the palisade cells
Palisade mesophyll - light absorption happens here in the chloroplasts
Chloroplasts - contains chlorophyll which absorbs light energy
Stomata - small pores which allow for the exchange of gases
Spongy mesophyll - where gas exchange happens
Lower epidermis - contains stomata cells
There are different factors which influence the rate at which photosynthesis can take place. For photosynthesis to take place at the optimum rate, all these factors must be at the ideal level. This is difficult to achieve. So let’s take a look at them.
Temperature
Concentration of carbon dioxide
Now that you know a bit more about photosynthesis - the things that affect the rate at which it takes place and the parts of the leaf involved - have a listen to Photosynthesis - part 2 to consolidate that knowledge. This is, learning made easy!
