Answer:
1.Plant absorbing water from the soil.
Explanation:
Osmomsis occurs by the movement of a water from a region of higher concentration of water molecules to a region of lower concentration of water molecules, through a semi permeable membrane,
<em><u>OR</u></em>
It occurs as a result of movement of substance molecules from a region of lower concentration to a region of Higher concentration of the substance.
<em><u>Note</u></em><em><u>:</u></em> The higher the concentration of the substance molecules,the lower the concentration of water molecules.
Single celled organisms such as amoebas, especially those that live in fresh water, continually gain water from their surrounding environment by osmosis. This water is pumped into a contractile vacuole which fills with fluid and periodically fuses with the cell membrane, releasing its contents to the exterior. Thus the amount of water actively transported out of the cell is equal to the amount of water entering the cell due to osmosis and there are no variations in the tonicity of the cell. This is homeostasis at a simple level. Without the contractile vacuole, the amoeba would continue to absorb water until its cytoplasmic contents were diluted to such an extent that metabolism no longer occurred and it would die.
Daughter cells are cells which are genetically identical to parent cells because they have the same type and number of chromesomes
