Question

One function of the central vacuole in plant cells is facilitating cell growth: the central vacuole absorbs water and increases in size, expanding the volume and size of the plant cell while doing so. Animal cells, however, do not grow by this method. What is an essential difference between animal and plant cells that could explain how a plant cell can withstand this expansion of the central vacuole?

Animal cells, however, do not grow by this method. What is an essential difference between animal and plant cells that could explain how a plant cell can withstand this expansion of the central vacuole? Plant cells grow at a slower rate than animal cells. The plant cell wall provides a more rigid structure. Animal cells have a similar organelle that produces the same effect as the central vacuole. Plant cells cannot divide.

Answer 1

The right answer is The plant cell wall provides a more rigid structure.

Plant cells are differentiated from animal cells by the cell wall (among others, they differ in size, vacuoles and the presence of chloroplasts). This wall, called the pectocellulosic wall (composed of pectin and cellulose), gives a rigid structure to the cell and a polygonal morphology to the cell.
