heterotroph - Organisms that cannot synthesise their own food, and
therefore rely on other food sources found within the oxygen-rich environment.
Many bacteria and fungi are heterotrophs, and are parasitic therefore leech
the energy from other organisms in order to survive
resistance - Antibiotics
are used in medicine due to their capability of inhibiting or neutralising
alien agents that enter the human body. Antibiotics are naturally produced
by organisms as a means of defense and hence survival. Through natural selection,
organisms that fall prey to antibiotics begin to develop a resistance, and
the effects of the antibiotics diminish over time until the organisms are
immune to its effect.
- Pertaining to the diversity and frequency of organisms in a given

of certain physical and chemical characteristics of an environment, such as
tundra, grassland etc.
- a polysaccharide that is the chief constituent of all plant
tissues and fibers.
- Chloroplasts contain
chlorophyll, a photosynthetic pigment used in the process of photosynthesis.
The chief structures within the chloroplast are the stroma and granum, which
host the photochemical and thermochemical stages of photosynthesis.

- An inflammatory disease of the skin, characterized by the presence
of redness and itching, an eruption of small vesicles, and the discharge of
a watery exudation, which often dries up, leaving the skin covered with crusts;

- membranous tissue covering internal organs and other internal surfaces
of the body.
- The genome of

- a complex polymer; the chief non-carbohydrate constituent of wood;
binds to cellulose fibers to harden and strengthen cell walls of plants.
- Living organisms
that can be seen with the naked eye.
- Living organisms
that cannot be seen with the naked eye; requires using a microscope.
- cellular organelle containing pigment, especially in plants, e.g.
- free-living or colonial organisms with diverse nutritional and
- a skin disease
of adults (more often women) in which blood vessels of the face enlarge resulting
in a flushed appearance
Glands - a cutaneous
gland that secretes sebum (usually into a hair follicle) for lubricating hair
Management - To
manage or maintain an area that will meet the needs of the present without
compromising the ability of future generations to meet their own needs.
- Existing or being everywhere, or in all places, at the same time;
Acid - a white tasteless odorless crystalline product of protein
metabolism; found in the blood and urine
