Depolarization is to excitation, while Hyperpolarization is to inhibition.
Option 4 is correct.
Hyperpolarization is opposite of Depolarization.
Depolarization is a process by which cells undergo a change in membrane potential. It is a process of shift in electric charge that results in less negative charge inside the cell.
Hyperpolarization is when the membrane potential becomes more negative at a particular spot on the neuron’s membrane.
Palisade mesophyll cells are closely packed to absorb the maximum light. They are at right angles to the surface of leaf to reduce the number of cross walls. Large vacuole pushes chloroplasts to the edge of a cell. Chloroplasts at edge enable short diffusion path for carbon dioxide and to absorb maximum light.
