Question

Anna waters her plants with salty water to help them grow better. Is her thinking correct?

Answer 1

Not unless the plant is a halophyte (salt-lover).

Answer 2

No. they need fresh water

Answer 3

Salt in the water makes the water less available to plants (more difficult to absorb). Think about osmosis. And if salt (sodium ions) gets into plant cells, they cause damage to plant cells.

Answer 4

Not unless they are plants that typically grow in salt marshes.
