Explanation:
Guard cells are can be described as a special group of plant cells that are located or can be found in the epidermis of plants. They come in the shape of a kidney.

This essential material in which the guard cell regulates/ control is an important part of plant photosynthesis, therefore they play an important role in the process through which plants manufacture their food.

The vacuoles in a plant cell are much more larger and take up a large portion of the cell but animal cells vacuoles tend to be smaller. The plant cells vacuole is permanent when the animals is temporary. A plant cells vacuole is formed by budding off the membrane, the animal cells vacuole is formed by the organelle called the Golgi body.
