Cells are the base unit of living organisms. At the beginning of life, the first organisms must have been single cells like today's bacteria. All organisms have evolved from that simplest prokaryotic cell, and from unicellular, multicellular organisms evolved. Also, all of biochemistry changes with Natural Selection, as does genetics. The biochemistry of the cell and cell differentiation has evolved. Photosynthetic cells, immune cells, nervous cells.... All have evolved with the higher organisms and have given them their identities of having neurological systems, immune systems or the ability to photosynthesise. Since life's basic unit is the cell, the basic unit of evolution (of the phenotype) is indeed largely the cell too. From zygote develops organism within the constraints of that species' evolution, cell by cell by cell by differentiated cell.
In Darwin's theory, natural selection plays the key role. Organisms vary through random mutations--slight changes from their parents. The environment determines which are most likely to survive. In Lamarck's theory, changes in phenotype are inherited. This is now known to be (largely) incorrect.
Phenotype - outwardly observable as opposed to Genotype - genetic characteristics Eye color is something individuals may share, but it is possible they are genetically different, even for the alleles in question. Outside genetics, other terms are morphology, and largely for plants is 'habit', meaning how it grows, looks, etc.
Homeostasis and Thermodynamics of Metabolic Pathways:Metabolism is a largely circular process of energy conversion in cells of living organisms. Chemical energy is extracted from nutrients (catabolism) and this energy is in turn used to synthesize new molecules (anabolism) from the same type of nutrients to maintain the structure and function of an organism. To accomplish both, say energy extraction from and biosynthesis of proteins, metabolism of living cells is a spatial and temporal network of chemical reactions close to, but never at chemical equilibrium. Living organisms maintain a state of metabolic homeostasis which can be viewed as a steady-state throughput or flow of energy and metabolites to sustain body functions and structures.Respiration and photosynthesis are catalytically possible only because of the coordinated activity of hundreds of proteins that belong to deferent sets of pathways in different compartments of cells and/or organisms. Understanding the structural and functional complexity that provides reductive synthesis of glucose as well as oxidative degradation is the same as understanding the mechanism of cellular metabolism.

a variety of different kinds of molecules.Living organisms are made up of a variety of many different kinds of molecules. Some molecules, such as water and salt, are small. Other molecules, such as carbohydrates, fats, proteins, and DNA are large.

Their functional groups.
The chemical largely responsible for the breakdown of ozone layer is CFC. These chlorofluorocarbons release chlorine which deplete upto 100,000 molecules per chlorine molecules.
The most important elements that largely contribute to plants are Hydrogen, oxygen and carbon dioxide.
The colors of fireworks are largely the result of the burning of tiny particles of metallic elements.
Natural gas is a fossil fuel consisting largely of methane (CH4).
I have no knowledge that they are. The original macaroon (a small sweet cake consisting largely of ground almonds and almond paste) was Italian.
A black powdery or flaky substance consisting largely of amorphous carbon, produced by the incomplete burning of organic matter.
