Two Types of Coevolution
Coevolution is common among organisms participating in a mutual interaction. In mutualism, both the organisms benefit from each other. When coevolution occurs among mutually benefiting species, it is called mutualistic coevolution.
When coevolution is found among species that have negative effects on each other, it is called competitive coevolution. There are two kinds of interactions between species that can lead to competitive coevolution:
<span><span>Predation is when one organism kills and eats another organism. The prey is the species that gets eaten by the predator, which is of course the species that eats the prey.</span><span>Parasitism is when one organism benefits by damaging, but not killing, another organism. The parasitespecies benefits from this relationship, while the host species is negatively affected.</span></span>
Monocots differ from dicots in four distinct structural features: leaves, stems, roots and flowers.
But, the differences start from the very beginning of the plant's life cycle: the seed. Within the seed lies the plant's embryo. Whereas monocots have one cotyledon (vein), dicots have two. This small difference at the very start of the plant's life cycle leads each plant to develop vast differences.
