What are two features of aloe vera's roots that allow it to adapt to its dry environment?
This plant is a succulent which means it is adapted to hot dry climates. It retains water in its thickened, fleshy leaves. It's roots have a fungus that penetrates the cortical cells. This fungus is called an arbuscular mycorrhiza and it helps the plant to better capture nutrients from the soil including nitrogen, sulfur and phosphorus. This type of relationship is called symbiosis and it is actually an example of mutualism between the fungus and the aloe vera plant. The roots are fairly short and lay flat embedded in the earth. Sometimes,even the roots are capable of water storage. Some aloes have a thick underground rootstock that resprouts indry areas that have fires.
