marigolds, and Coca-Cola.

Plants are organisms that, like everything else living, are made up of cells and

they are in the Plantae Kingdom (Gale encyclopedia of science, p. 2893-2894). The

diseases are called disorders and are most common among plants. Some disorders are

caused by lack of nutrients, too much or too little water, polluted soil, or polluted air.

Weather can effect a plant's growth too, for example: too much or too little sun

(Gale Encyclopedia of Science, p. 2904)

Now I'm going to talk about Marigolds. Marigolds are popular half-hardy

annuals that are grown for their bright, wide flowers and bushy mounds of lacy,

green leaves. The African or American Marigolds (Tagetes Erecta) are large with 18-

36 inch long stems. They have large flowers about two to four inches wide that are

yellow, orange, or bicolored. The French Marigolds " are much daintier", with small

single flowers that also about two to four inches wide. They come in yellow, red, and
