Imbibition occurs when the seed is exposed to water. The seed absorbs water though its seed coat. As this happens, the seed coat softens.
The arranged events in respect to the function of the channels, ion permeability, and changes in membrane potential from top to bottom include:
1. opening of voltage-gated Na+ channels
2. Na+ ion flow into the neuron increases
3. depolarization of the membrane to +30 mV
4. K+ ion flow out of the neuron increases
5. repolarization of the membrane.
<h3>What is Membrane potential?</h3>
This is defined as the difference in electric potential between the interior and exterior parts of a biological cell and also refers to the potential gradient which facilitates the movement of ions in a cell in one direction.
In a cell, the series of events which occur according the variables such as ion permeability is opening of voltage-gated Na+ channels and is usually ended by the repolarization of the membrane.

Answer:
Since they need to float, leaves on the surface of plants are flat. 6. The presence of air sacs enables them to float. Their roots are smaller so water can spread freely and directly into the leaves
