Practise MYP Biology questions on 5.2 Cell Division and review the explanations to check your understanding.
Use these questions for topic practice and to find ideas you want to revisit in your notes or lessons.
Which statement best explains why a decrease in the surface area to volume ratio limits cell size?
In terms of the cell cycle, why is damage to the spinal cord or heart muscle often considered irreversible?
True or False: Because DNA must be unpacked to allow for the copying of genetic material, a cell cannot simultaneously organize its DNA into compact chromosomes for movement.
In a large cell with a low surface area to volume ratio, which specific movement is most likely to be delayed, leading to the accumulation of toxic byproducts in the cytoplasm?
True or False: During interphase, DNA is tightly packaged into chromosomes to facilitate the copying process.
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
True
False
True
False
Nutrient entry from the surface
mRNA moving from the membrane to the nucleus
Oxygen diffusion to the center
Waste products moving from the center to the surface
