Question

multiple choice question
which of the following is the most important factor that limits the size of cells?
o amount of dna to code for all the cells proteins
o amount of mitochondria needed to satisfy the cells energy needs
o diffusion of substances in and out of the cell
o rate of protein synthesis in the cell

Explanation:

As cells grow larger, the surface - area - to - volume ratio decreases. Diffusion of substances like nutrients and waste in and out of the cell becomes less efficient. This limits cell size as cells need to maintain efficient exchange of materials. DNA amount, mitochondria amount, and protein synthesis rate are important for cell function but not the most limiting factor for cell size.

Answer:

Diffusion of substances in and out of the cell
