Question

water flows naturally into the roots of plants by this process. osmosis exocytosis dialysis endocytosis

Explanation:

Osmosis is the process where water moves across a semi - permeable membrane from an area of lower solute concentration to an area of higher solute concentration. Plant roots have a semi - permeable membrane (cell membrane of root cells). Soil water has a lower solute concentration compared to the root cell cytoplasm. So, water moves into the roots by osmosis. Exocytosis is the process of vesicles fusing with the plasma membrane to release their contents outside the cell. Dialysis is a medical process (though also a general process of separation) mainly used for filtering waste from the blood (in medical context) or separating substances based on size. Endocytosis is the process of a cell taking in substances by engulfing them with its membrane.
