Surface Area to Volume Ratio

As cells grow, their volume increases faster than their surface area, which can limit nutrient supply and waste expulsion.

Cellular Reproduction

The process by which cells grow and divide, allowing for growth and repair in organisms.

Diffusion

The movement of substances from an area of higher concentration to an area of lower concentration.

Efficiency of Transport Systems

Smaller cells can maintain more efficient systems for transporting substances across their membranes.

Cell Signaling Proteins

Proteins that facilitate communication within the cell, impacting cell size and function.

Interphase

The stage in the cell cycle where the cell grows, performs normal functions, and replicates its DNA.

Mitosis

The stage of the cell cycle where the cell's nucleus and nuclear material divide.

Cytokinesis

The division of a cell's cytoplasm that results in the formation of two separate cells.

G1 Phase

The first stage of interphase, where the cell grows and prepares for DNA replication.

S Phase

The second stage of interphase, where the cell copies its DNA in preparation for division.

G2 Phase

The third stage of interphase, where the cell prepares for the division of its nucleus.
