If the agar blocks were actual cells, which 1cm,2cm,3cm would be most efficient in terms of permitting materi

Question

als to enter and leave the cell?explail please

Answer 1

the 1cm block, because of the surface area- to volume ratio is larger with smaller cells. The reason why cells cannot grow too big is because the ratio goes down, and thus cells cannot absorb enough nutrients to maintain the life for the entire cell

Answer 2

The smaller blocks would be more efficient. Smaller blocks and smaller cells have a greater surface area to volume ratio, meaning that they have a higher ratio of surface area to let materials enter and leave the cell.

Answer 3

1cm, it is due to the surface area: diffusion rate, the higher the surface area, the faster diffusion will occur.
