ecosystem
A large complex molecule, such as nucleic acids, proteins, carbohydrates, and lipids, with relatively large molecular weight. Biologically important molecules that are technically polymers
macromolecule
molecule
A chemical structure consisting of at least two atoms held together by a chemical bond
Organ
Collections of tissues that work together to carry out a common general function. Present not only in higher level animals but also in plants.
Organ System
Collections of tissues that work together to carry out a common general function. Present not only in higher level animals but also in plants.
Compartments inside the cell that contain specific groups of macromolecules and carry out specific cellular functions. One of these is the nucleus; it encloses the DNA within the cell.
organelle
Organism
Individual living entities that survive and reproduce as a unit. For example, each tree in a forest.
Consists of all the individuals of a species living within a specific area
