It has taken millions of years for trees to evolve into the organism they are today so it’s no surprise that many of us have no idea how exactly each particular piece works. In fact, trees were around long before the dinosaurs and have outlived them after their extinction 65 million years ago. In this blog, we’re going to focus on the leaf…


The leaf itself has very tiny structures inside the plant cells called chloroplasts and this is where photosynthesis takes places. Each of these chloroplasts contains a green pigment that is known as chlorophyll and it is this that absorbs the light energy from the sun that is necessary for photosynthesis.


As with many organisms, leaves have had to adapt over thousands of years in order to become as efficient as they are today. For example, leaves have become thinner in order to supply a shorter distance for the diffusion of carbon dioxide, they have stomata to allow this carbon dioxide to diffuse into the leaf and a network of veins to transport water around.


Deep inside the leaf, there are hundreds of thousands of plant cells which contain parts that are so small, they can only be seen with a very advanced microscope. These parts include the wax cuticle which minimises water loss, the upper and lower epidermis which allow for light to pass through and the palisade mesophyll which contains most of the chloroplasts.

Understanding how something so small is able to carry out such an important process is always interesting which is why the team here at Ashley Tree Services love using our blogs to educate our readers.
