What following ? actually the cell will gain more water by diffusion and will let more sodium chloride ions in because they will move from high concentration to low concentration
During the lifecycle of the plant we can encounter both haploid and diploid forms.
Haploid form of the plant is called a gametophyte. This form was created from spore and enables creation of haploid gametes in the next stage.
If the Na+ voltage-gated channels in a muscle cell open, the Na (sodium) ions rush inside the muscle cell and makes the cell more positive as Na ions carry positive charge on it. Due to the entry of positively charged ions inside the cell, the cell becomes less negative and more positive. This is called depolarization of cell.
