The diagrams show what happens to the shape of a plant cell place in distilled water. Explain why the cell swells and becomes turgid. Name the process involved.

the name of the process should be osmosis

Explanation: Reason being that plant cells are hypertonic because they have a cell sap so when they are pout in distilled water  which is a hypotonic solution, it then absorbs water by osmosis and swells up and become turgid. But they do not burst because they have a cell wall that develops a wall pressure that balances the turgor pressure exerted by turgid cells

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
