Cells use oxygen to assist in cellular respiration. This type of respiration, called aerobic cellular respiration, converts stored energy into a usable form. The first stage of aerobic cellular respiration, glycolysis, can be performed without oxygen.
A persuasive speech is a specific type of speech in which the speaker has a goal of convincing the audience to accept his or her point of view. The speech is arranged in such a way as to hopefully cause the audience to accept all or part of the expressed view.
The persuasive purpose is used to convince, or persuade, the reader that the opinion, or assertion, or claim, of the writer is correct or valid. Persuasion is more selfish than argument (debate). Argument attempts to arrive at a logical solution to an issue.
