Question

Plant and animals cells are very similar structurally, though some differences do exist. The vacuole is one organelle that differs in plant and animal cells. Which statement BEST elaborates on the reason for this difference?

A)
Vacuoles help plants make their own food by converting light energy, Animals do not make their own food.


B)
Animal cells have large vacuoles to remove waste, while plant cells do not produce waste and have small vacuoles.


C)
Vacuoles are much larger in plant cells than in animal cells, because they tend to hold more water to stay upright.


D)
Vacuoles in animal cells are porous, so oxygen can pass, while those in plant cells have solid walls to keep water inside.

Answer 1

The answer is C. When a vacuole is filled with water, turgor pressure exist, it can keep the cells turgid and therfore to make the plant stay upright and prevent it from wilting.

Answer 2

The correct answer is; Vacuoles are much larger in plant cells than in animal cells, because they tend to hold more water to stay upright.

A vacuole is a membrane bound organelle in plants and animals cells which works by holding various solutions or molecules. The vacuoles are much larger in plant cells than in animal cells. In plant cells, the vacuole may be used to store water which help to support the plant. The solutes inside the vacuoles absorb water which makes the cells to become inflated. This allows the soft parts of the plants structure such as leaves to stay upright. Therefore, making plants to retain their shape and turgidity.
