    What physical and metablic constraints limit cell size? What prbomes would an enormous cell encounter?/ What adaptations might help a very large cell survive?

    Usually, the biggest problem a very large cell has is transport. The ejection of waste and the intake of resources is done through the cell's membrane. The larger a cell gets, the farther away its innards are from the membrane. This makes getting rid of waste and receiving resources difficult and time consuming for those inner reaches of the cell. At a certain size threshold (though I don't know what it is, exactly), it becomes too much of a burden and the cell will begin to die. It follows, then, that adaptations in intracell transport would help individual cells to grow to larger sizes.

    Seriously, if you're going to ask people to do your homework for you, couldn't you AT LEAST show us you've done SOME work yourself?

    Cells can be quite large. The fertilized emu or ostrich egg could be considered to be a cell. A gigantic cell.

    Neurons in a giraffe can be several meters long going from neck to toe. Of course the axon of the neuron takes up most of the length here.

    I'm not sure what the largest functional cell is, but I am sure google knows.

    my guess is you'll probably find the largest cell in the blue whale - everything about it is gigantic : you could swim through its arteries

    V/A should be smaller for a cell to act as the structural and functional unit of life.
