# Term Definition
1 Adrenaline A hormone secreted by the adrenal medulla;
also called apinephrine.
2 Algae Simple plants containing chlorophyll.
3 Amino Acid An organic compound containing an amino and
a carboxyl group; the building blocks of
proteins.
4 Amphibians A class of vertebrates capable of living both in
water and on land. The larval forms have gills
and the adults have lungs; includes frogs and
toads.
5 Angiosperms The class of flowering plants, with seeds
inclosed in fruit.
6 Antibiotic A substance that destroys a microorganism or
inhibits its growth.
7 Antibody A substance produced by the body to combat
the injurious effect of a foreign substance
(antigen).
8 Aorta The main artery leaving the heart.
9 Arachnids A class of arthropods with no antennae and four
pairs of legs; includes spirders, scorpions, ticks,
mites, and king crabs.
10 Arthropods The phylum of segmented invertebrates with
joined appendages and an extoskeleton
11 Bacteria Unicellular organisms without a distinct nucleus
and usually without chlorophyll
12 Bile A yellowish-green fluid that helps in the
digestion of fats.

13 Budding Asexual reproduction by the splitting of a new
organism from the parent.
14 Capillary The smallest blood vessel that carries blood
between an artery and a vein
15 Carbon cycle The exchange of carbon between living things
and their environment.
16 Cell The basic unit of organic structure and life.
17 Cellulose The woody tissue of plants.
18 Chordates The phylum characterized by a spinal chord;
includes the vertebrates.
19 Chromosome A body in the cell nucleus that is the bearer of
genetic information.
20 Cross-pollination The transfer of pollen from one plant to a flower
on another plant
21 Crustaceans Arthropods with gills and two pairs of antennae
like lobsters and crabs.
22 Cytoplasm The substance of the cell outside the nucleus.
23 DNA The compound in the chromosomes that stores
genetic information as a molecular code.
24 Dominant The one of two alternative genetic traits that is
displayed in a heterozygous individual.
25 Ecology The study of organisms and their environment.
26 Embryo An organisms in the early stages of
development.
27 Enzyme A protein that serves as an organic catalyst for
metabolic reactions.
