VladimirAG [237]

Answer:

The correct answer is: Vacuoles in plants are much larger than those in animals.

Explanation:

The cell membrane of animals is not thicker than those in plants. In addition, plant cells have a thick cell wall surrounding the cell membrane that is made of cellulose and provides great protection against osmotic and mechanical stress.

Vacuoles in plants ARE much larger than vacuoles in animals, because plant cells r<u>equire much more water</u> and other substances to function properly. Animals, on the other hand, can ingest water and nutrients through food.

Animal cells DO have chromosomes. Every organism has chromosomes in their cells: prokaryotes have one single circular chromosome, while eukaryotes have many linear chromosomes (humans, for example, have 46 chromosomes).

Plant cells HAVE chloroplasts, as these organelles are crucial, since they participate in the process of photosynthesis - which is fundamental for the nourishment of the plant.

The statement that belongs in Kiko's report is Vacuoles in plants are much larger than those in animals.
