A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding.
Peripeteia is the reversal from one state of affairs to its opposite. Some element in the plot effects a reversal, so that the hero who thought he was in good shape suddenly finds that all is lost, or vice versa. Anagnorisis is a change from ignorance to knowledge.
Diagram of antheridium anatomy. An antheridium or antherida (plural: antheridia) is a haploid structure or organ producing and containing male gametes (called antherozoids or sperm). It is present in the gametophyte phase of cryptogams like bryophytes and ferns, and also in the primitive vascular psilotophytes.n bryophytes, the antheridium is borne on an antheridiophore, a stalk-like structure that carries the antheridium at its apex. In many gymnosperms and all angiosperms, the male gametophytes have been reduced to pollen grains and their antheridia have been reduced to a single generative cell within the pollen grain.
