Biology Prefixes and Suffixes: (-troph or -trophy)

Definition:

The suffix (-troph or -trophy) refers to nourishment. It is derived from the Greek trophos, which means one who nourishes or is nourished. Troph- can also be used as a prefix.

Biology Prefixes and Suffixes: (-troph)

Examples:

Autotroph (auto-troph) - an organism that is self nourishing or capable of generating its own food.

Auxotroph (auxo-troph) - a strain of microorganism, such as bacteria, that has mutated and has nutritional requirements that differ from the parent strain.

Chemotroph (chemo-troph) - an organism that obtains nutrients through chemosynthesis (oxidation of inorganic matter as a source of energy to produce organic matter).

Embryotroph (embryo-troph) - all nutritive material supplied to mammalian embryos.

Hemotroph (hemo-troph) - nutritive materials supplied to mammalian embryos through the blood supply of the mother.

Heterotroph (hetero-troph) - an organism that relies on organic substances, such as plants and animals, for nourishment.

Histotroph (histo-troph) - nutritive materials, supplied to mammalian embryos, derived from maternal tissue other than blood.

Metatroph (meta-troph) - an organism that requires complex nutritive sources of carbon and nitrogen for growth.

Phagotroph (phago-troph) - an organism that obtains nutrients by phagocytosis (engulfing and digesting organic matter).

Phototroph (photo-troph) - an organism that obtains nutrients by using light energy to convert inorganic matter into organic matter through photosynthesis.

Prototroph (proto-troph) - a microorganism that has the same nutritional requirements as the parent strain.

Biology Prefixes and Suffixes: (-trophy)

Examples:

Atrophy (a-trophy) - a wasting away in an organ or tissue due to lack of nourishment or nerve damage.

Dystrophy (dys-trophy) - a degenerative disorder resulting from inadequate nutrition.

It also refers to a set of disorders characterized by muscle weakness and atrophy (muscular dystrophy).

Eutrophy (eu-trophy) - refers to proper development due to healthy nutrition.

Hypertrophy (hyper-trophy) - excessive growth in an organ or tissue due to increase in cell size, not in cell numbers.

Myotrophy (myo-trophy) - nourishment of the muscles.

Oligotrophy (oligo-trophy) - a state of poor nutrition.

Onychotrophy (onycho-trophy) - nourishment of the nails.

Osmotrophy (osmo-trophy) - the acquiring of nutrients through the uptake of organic compounds by osmosis.

Osteotrophy (osteo-trophy) - nourishment of bone tissue.

Biology Prefixes and Suffixes: (troph-)

Examples:

Trophallaxis (tropho-allaxis) - exchange of food between organisms of the same or different species.

Trophobiosis (tropho-bi-osis) - a symbiotic relationship in which one organism receives nourishment and the other protection.

Trophoblast (tropho-blast) - outer cell layer of a blastocyst that attaches the fertilized egg to the uterus and later develops into the placenta. The trophoblast provides nutrients for the developing embryo.

Trophocyte (tropho-cyte) - any cell that provides nutrition.

Trophopathy (tropho-pathy) - a disease due to a disturbance of nutrition.
