unicellular organisms carry out all the functions of life
multicellular organisms show emergent properties
stem cells retain the capacity to divide and have the ability to differentiate along different pathways
bacterial cells divide by binary fission
tumours (cancers) are the result of uncontrolled cell division and that these can occur in any organ or tissue
interphase is an active period in the life of a cell when many metabolic reactions occur, including protein
synthesis, DNA replication and an increase in the number of mitochondria and chloroplasts
growth, embryonic development, tissue repair and asexual reproduction involve mitosis
