Question

multiple-choice question
why are we not one big cell?
all of the above
materials would not arrive on time
smaller cells are more efficient at transporting materials.
the cell could burst if its too big
rewatch

Explanation:

Large single cells face multiple limitations: as cell size increases, the surface area to volume ratio decreases, making material transport inefficient so nutrients/wastes can't move in/out on time. Smaller cells have a higher surface area to volume ratio, which makes them much more efficient at transporting materials. Additionally, a very large cell would be at risk of bursting due to structural stress and osmotic pressure. All the listed options are valid reasons.

Answer:

all of the above
