Macromolecules
can be composed of two or more atoms of a single element
Molecule
microscopic, is the smallest unit that can perform all the activities associated with life.
Cell
Macromolecules associate with one another to form compartments called
Organelles
functional units that perform specific roles.
Organs
associations of cells that perform specific functions.
Tissues
groups of members of the same species that live together in the same area
Population
distinct, living entities.
Organism
is a community together with its nonliving environment.
Ecosystem
consists of all the populations of different organisms that live and interact within an area.
Communities
The chemical energy that plants store in food molecules is released within the cells of plants, animals, and other organisms through

Growth
does not involve the union of gametes (reproductive cells).
Asexual reproduction
in plants involves the union of gametes
Sexual Reproduction
the formation of a new individual by sexual or asexual means
Reproduction
Cumulative genetic changes in a population of organisms from generation to generation.
Evolution
are characteristics that enable an organism to better survive in a certain environment.
Adaptations
the tendency of organisms that have favorable adaptations to their environment to survive and become the parents of the
next generation.
Natural Selection
have nuclei and other membrane-bounded organelles.
Eukaryotes
often adapted to harsh conditions and frequently live in oxygen-deficient environments
Kingdom Archaea
lack nuclei & other membrane-bounded organelles.
Prokaryotes
protozoa, algae, water molds, and slime molds
single-celled or simple multicellular organisms.
