Question

15 points. what is the source of dissolved phosphates that can become available to plant uptake? select all that apply.

Explanation:

Plants take up dissolved phosphates in the form of phosphate ions ($PO_{4}^{3 - }$). This is essential for plant growth as phosphorus is a key macronutrient involved in many biological processes such as energy transfer, nucleic - acid synthesis, and cell - membrane formation. $SO_{4}^{2 - }$ is a sulfate ion which is a source of sulfur for plants and not a phosphate source.

Answer:

$PO_{4}^{3 - }$
