extracellular matrix (ECM) - a substance in which the cells of an animal tissue are
embedded; consists of protein and polysaccharides
biodiversity - The variety of living things, encompassing genetic diversity, species
diversity and ecosystem diversity

mitochondrion. The intermembrane space is the narrow region between the inner
and outer membranes.
cellulose - a large polysaccharides composed of many glucose monomers linked
into cable-like fibrils that provide structural support in plant cell walls.
hypotonic solution - in comparing two solutions, the one with the lower
concentration of solutes; cells in such a solution will take up water from their
surroundings.
ozone layer - the layer of ozone (o3) in the upper atmosphere that protects life on
earth from the harmful ultraviolet rays in sunlight
pH scale - a measure of the relative acidity of a solution, ranging in value from

called tubulins. microtubes from the basis of the structure and movement of cilia
and flagella.
nucleus - an atom's central core, containing protons and neutrons/ The genetic
control center of a eukaryotic cell.
systems biology - an approach to studying biology that aims to model the dynamic
behavior of whole biological systems.
phytoplankton - algae and photosynthetic bacteria that drift passively in aquatic
environments.
electronegativity - the attraction of a given atom for the electrons of a covalent bond.
