Pores in the cell wall allow water and nutrients to move into and out of the cell. The cell wall also prevents the plant cell from bursting when water enters the cell. Microtubules guide the formation of the plant cell wall. Cellulose is laid down by enzymes to form the primary cell wall.Homeostasis refers to the balance, or equilibrium, within the cell or a body. It is an organism's ability to keep a constant internal environment. Keeping a stable internal environment requires constant adjustments as conditions change inside and outside the cell. The adjusting of systems within a cell is referred to as homeostatic regulation.Calculating Wave Speed from Wavelength and Wave Frequency. The equation for wave speed can be used to calculate the speed of a wave when both wavelength and wave frequency are known.
