Good CU of tree branches, with buds and blossoms, birds tweeting, time-lapse of plant growing - phallic. Growth of chicken embryo studied, good CUs. Good chicken hatching, chirping. Still of human embryo, VO says it's the size of pinhead. Boy plays in sand pit. Still of cells. Rabbit egg cell under microscope, follows growth after fertilization, including cells dividing and multiplying. Animation of cells growing, dividing. Illustration of rabbit superimposed over cells dividing. Animation illustrates cell make-up, cytoplasm, nucleus, chromosomes, DNA, molecules, genes. Animation of cells splitting and chromosome distribution, mitosis - scratchy, audio track jumps. Andre Bayer, noted biologist, plucks seed pods off blood lily. CU of knife cutting piece of pod, squeezing juice into petri dish. Phase fase ? microscope photographs miotosis of lily, chromosomes visible. CU scientist looking thru microscope. Animated diagram showing chromatin, prophase, centromere, spindle fibres. Prophase shown for real under microscope. Next is metaphase, followed by anaphase, finally the telophase. CU of fingers on microscope dials. Looking at differences in plant and animal formations. CU man's forehead with cut, bleeding. Blood thickens and forms scab. VO re cell replacement. Veins (microcinematography), blood rushing thru veins. Washing hands in basin, drying with paper. Skin cells, animation, re replacement, cancer cells. Sign, 'Reactor Area'.
