The total volume of plant cells is often significantly greater than the total volume in animal cells. The most reasonable explanation for this observation is that A) animal cells are spherical, whereas plant cells are elongated.
B) plant cells are capable of having a much higher surface-to-volume ratio than animal cells.
C) plant cells have a much more highly convoluted (folded) plasma membrane than animal cells.
D) plant cells contain a large vacuole that occupies much of the volume of the cell.

D

Explanation:

In plant cells, the vacuoles are much larger than in animal cells. When a plant cell has stopped growing, there is usually one very large vacuole. Sometimes that vacuole can take up more than half of the cell's volume. The vacuole holds large amounts of water or food.

Irrigation

Explanation:

Condensation is not the answer since it is only for forming clouds. Recreation is not it since just a casual activity. Transportation can be many things. But irrigation is a process in growing crops. It is used to water the crops.
