<span>Turgor pressure (hydrostatic pressure) of the plant can be described as the force within the cell that pushes the plasma membrane against the cell wall. Turgor pressure within plant cells is regulated by osmosis (travel of the water from an area with a low concentration of solutes, to one with a higher-solute concentration). There are two mechanisms for the regulation of turgor pressure.</span>
<span>1. The semipermeable membrane, which only allows some solutes to travel in and out of the cell. Also, it can maintain a small amount of pressure.
</span> <span>2. Transpiration by opening and closing of stomates to control evaporation from leaves<span>, which results in water loss and decreases turgidity in cells.</span></span>
The cardiac muscle is only in the heart because it has special characteristics such as being able to make sustained contractions, coordinated movement, and rapid conduction. Hope this helps!
<span>The option which is responsible for the exchange of gases in a leaf is D. the stomata. Stomata are tiny pores in leaves that enable the flow of gases throughout a plant. The phloem transports sugar, spongy is an adjective referring to something that resembles a sponge, and mesophyll is the part of the leaf that contains chloroplasts.</span>
