Question

In the picture, the stomata on the underside of the leaf will ____________ when the turgor pressure within the guard cells increases to full capacity. A) swell B) shrink C) open fully D) close tightly

Answer 1

And the answer is  C. open fully

Answer 2

The right answer is C) open fully

A stomate consists of two kidney-shaped stomal cells (guard cell) that delimit the stoma or ostiole orifice. The latter opens more or less, depending on the needs, depending on the turgor of the stomatal cells.

When the guard cells are turgid, the thinner and more flexible outer wall expands more than the thicker and stiffer inner wall. The cells curl and the ostiole opens.
