Photosynthesis

Plants aren't really that boring!!!

The tree and flower above are both examples of plants. At first glance, all they both are very different however they have one thing in common. They are both autotrophs, photoautotrophs to be precise. This means that they use light energy to convert water and carbon dioxide into every single compound that we may need. Humans however, well we're not autotrophs, instead we're heterotrophs which means we must eat something with these complex molecules and use them that way. If your slightly confused about this concept, take a look at the food chain below: 

Grass ---> Rabbit ---> Fox

In this case the grass is the autotroph whilst the rabbit and the fox are

heterotrophs

Chloroplasts districts?

Chloroplase are normally disc-shaped organelles that are between 2-10 um long (that's pretty small). They also like mitochondria, have a double membrane known as envelope. There is a space between the inner and outer membrane that is about 10-20nm wide (that's a millionth of a…
