| autotroph | <biology> An organism that makes its own food and does not require previously formed organic materials from the environment. Organisms that synthesise all their organic molecules from inorganic materials (carbon dioxide, salts etc.). Plants are classified as autotrophs because they use photosynthesis to make their own energy. May be photo autotrophs or chemo autotrophs, depending upon the source of the energy. Synonym: lithotrophic organism. Compare: heterotroph. (02 Jan 1998) |

| heterochromatin, facultative | Heterochromatin that need not always be heterochromatic but has the faculty to return to the normal euchromatic state. The inactive x chromosome is made up of facultatative heterochromatin. When a woman transmits that x to a son, it reverts to euchromatin and genetic activity. (12 Dec 1998) |
| facultative | Of parasites, optional. Compare: obligate. (09 Oct 1997) |
| facultative aerobe | <microbiology> An organism which is normally anaerobic but can also grow in the presence or oxygen. (15 Nov 1997) |
| facultative anaerobe | <microbiology> A microorganism which can survive without oxygen (is an anaerobe) but is not harmed if oxygen is present. (09 Oct 1997) |
| facultative heterochromatin | <cell biology> The heterochromatin which is condensed in some cells and not in others, presumably representing stable differences in the activity of genes in different cells. The best known example results from the random inactivation of one of the pair of X chromosomes in the cells of female mammals, (Lyonisation). (18 Nov 1997) |
| facultative hyperopia | Hyperopia that can be compensated by accommodation. Synonym: facultative hyperopia. (05 Mar 2000) |
| facultative parasite | An organism that may either lead an independent existence or live as a parasite, in contrast to obligate parasite. (05 Mar 2000) |
| facultative ponds | Ponds having an aerobic zone on the top and an anaerobic zone on the bottom. (05 Dec 1998) |
| facultative species | <ecology> Species that can occur both in wetlands and uplands, there are three subcategories of facultative species: 1. Facultative wetland plants (FACW) that usually occur in wetlands (estimated probability 67-99%), but occasionally are found in nonwetlands. 2. Facultative plants (FAC) that are equally likely to occur in wetlands or nonwetlands (estimated probability 34-66%). 3. Facultative upland plants (FACU) that usually occur in nonwetlands (estimated probability 67-99%), but occasionally are found in wetlands (estimated probability (1-33%). (09 Oct 1997) |
