How does a hibiscus flower move?

The movement of the hibiscus flower is accomplished through changes in electrolyte concentrations that cause water movement and changes in turgor pressure throughout the plant.

How does a plant's turgor pressure change?

Upon the stimulus calcium-permeable anion channels open to allow a flux of calcium ions into the cytoplasm of the cell causing it to depolarize. This electrical signal is propagated down the phloem to neighboring cells as sequential voltage calcium channels open. In response to the change in membrane potential voltage, gated potassium and chlorine channels open causing an efflux of ions. The increased concentration of ions outside of the cell creates an electrochemical gradient that pulls water out of the cell through osmosis. Aquaporins and hydrogen ion ATPase also help with the movement of water molecules. This causes a change in turgor pressure as water flows out of the flexor cells on the pulvinus and into the extensor cells to allow for bending of petals up to close the flower. The mechanism for hibiscus nyctinasty is an example of plant movement to improve fitness.

Why does water flow out of the flexor cells on the pulvinus and into the extensor?

This causes a change in turgor pressure as water flows out of the flexor cells on the pulvinus and into the extensor cells to allow for bending of petals up to close the flower. The mechanism for hibiscus nyctinasty is an example of plant movement to improve fitness.
