    		As plant cells freeze and thaw during spring frosts, copper ions (after spraying copper salts)may get pulled into cells and cause more damage than they would in the absence of frosts

    		They don't, apparently. It ice crystals form inside plant cells, the expansion ruptures the cell wall and it dies. But, some have natural anti-freeze.

    A fertilised cell divides into two, then four, then eight seemingly identical cells. By what mechanism do cells begin to specialise to form blood, nerve or bone cells, and what determines whether they become part of the head, feet or whatever?

    I just heard that they have fertilised a woman with her clone by using her DNA cells, obviously, and skin cells from her partner. How can this be a true clone if they used cells fron another person?

    There was a woman whose cells are bred in culture dishes in labs all over the world; a woman whose cells were so prolific that there is more of her now, in terms of biomass, then there ever was when she was alive. She died at the age of 31. Who was she?
