By performing photosynthesis, plants create everything they need to build all biomolecules. Is this true? Why or why not?(1 point)
Responses

This is true because photosynthesis produces glucose, and plants only need sugars, not amino acids or fatty acids.

This is true because photosynthesis produces glucose, which has carbon, hydrogen and oxygen—the building blocks for all biomolecules.

This is not true because plants need to sequester nitrogen from the soil to build amino acids.

The correct response is:

**This is not true because plants need to sequester nitrogen from the soil to build amino acids.**

While photosynthesis provides glucose, plants also need other nutrients, such as nitrogen, to synthesize amino acids and other biomolecules.

The correct response is:

**rusting.**

Rusting involves a chemical reaction where iron reacts with oxygen and moisture to form iron oxide (rust).
