Why must cells pump out extra ions

Biology
2 answers:

If the sodium ions are outside a cell, they would have to move the cell depending on its concentration gradient and the voltage across the membrane (the more negative charge within the membrane). So the cells pump the extra ions.

If sodium ions are outside of a cell, they will tend to move into the cell based on both their concentration gradient and the voltage across the membrane (the more negative charge on the inside of the membrane). So cells pump out the extra ions.

Which of the following apply to gymnosperm seeds EXCEPT:_______. a) enveloped by sporophyte tissues upon maturation. b) containe
Bess [88]

Answer:

Fully enclosed in an ovary

Explanation:

A gymnosperm is a group of a plant which can be distinguished from other groups of a plant is through the presence of seeds but they are not enclosed and are naked.

The seeds are considered naked as they are not fully enclosed in the ovary like in the angiosperms rather they are present as on modified leaves called sporophylls and the cones.

The seeds are sheltered by the sporophyll and when they mature are enclosed by the sporophytic tissues. Since they are not enclosed in the ovary, therefore, are considered the gymnosperms.

Thus, the selected option is correct.
