Answer:
A) The radial orientation of cellulose microfibrils in the cell walls of guard cells causes them to bow outward and open when the stomatal pore when turgid.
Explanation:
Stomata are pores on the surface of leaves that work as valves controlling the gas exchange in plants; they are bordered by a pair of curved guarded cells in charge of opening and closing by increasing or decreasing the stomatal pore area.
Guard cells walls structure consist of a combination of stiff cellulose microfibrils oriented along the circumference of the cells and a softer matrix material which makes it possible for stomata pore to open by increasing water pressure (turgor).
Option B states that when guard cells become turgid, they close the stomata. This is a false statement as we explained before.
Option C states that light (known stimulant for opening stomata) causes guard cells to become flaccid which is also false. Guard cells become turgid in order to open the stomatal pore.
Option A is correct.

i believe it's the first one
Explanation:
The main characteristic that differs the kingdom Fungi from all other kingdoms is the presence of cell wall made of chitin. Kingdom Animalia has no cell wall, while plants, bacteria, and some protists have cell walls but made of different polymers. The members of the kingdom do not photosynthesise and they are heterotrophs, like animals. The kingdom of fungi includes yeast, mold, mildew, and mushrooms and all of those groups are heterotrophs and have chitin cell wall. Yeasts are unicellular fungi, while molds, mildew (which are certain kind of molds), and mushrooms are multicellular fungi,
