Can be 1 cell (unicellular) or many identical cells (non differentiated) Can live independently, not unit of multicellular organization. React to their environment response helps ensure survival. Maintain an internal equilibrium homeostasis both the cell and organism have their own. Can grow and reproduce: unicellular divide in 2 by asexual reproduction binary fission, multicellular union of different cells by sexual reproduction sperm/ovum, genes have dna, genome undergoes decoding (transcription/translation), generates new cells, generates cell machinery. Are subject to evolutionary adaptations changes occur at genome and depends on selective pressures. Organize in terms of size biggest to smallest: ant, animal cell, bacteria, chloroplast, virus, protein, amino acid, atom. Metabolism absorption and transformation of chemical compounds, to obtain generate and use energy and eliminate waste products. Food microbiology study of pathogens which cause spoilage of food. Aristotle organisms created spontaneously from nonliving matter.
