Cell division Questionbank

Because the nucleus stops functioning in larger cells

Because membrane proteins become less efficient in larger cells

Because waste products block the entry of nutrients

Because volume increases cubically while surface area increases quadratically

Both cell types divide at the same frequent rate to ensure constant regeneration.

Intestinal lining cells divide more frequently than liver cells.

Liver cells divide more frequently than intestinal lining cells.

Neither liver cells nor intestinal lining cells divide once the organism reaches maturity.

The nucleus runs out of DNA to provide instructions

The cell lacks growth factors required for internal metabolism

The membrane cannot transport enough materials to support the internal volume

The cell's volume becomes too small to hold necessary organelles

The body lacks the growth factors required to signal these specific cells

The large size of these cells makes the surface area to volume ratio too low for division

These cells are post-mitotic and generally do not divide once matured

These cells divide so rapidly they create non-functional scar tissue

alternate

reverse

The nucleus produces more waste to compensate

Waste products take longer to reach the surface

Waste products reach the surface more quickly

The cell membrane becomes more permeable to waste

Skin cells and intestinal lining cells divide much more frequently than liver cells.

Liver cells divide much more frequently than skin cells and intestinal lining cells.

Skin cells and liver cells divide at approximately the same frequency.

Intestinal lining cells divide less frequently than liver cells.
