Which type of biomolecules are made up of fatty acids?(1 point)

By performing photosynthesis, plants create everything they need to build all biomolecules. Is this true? Why or why not?(1 point)
No, this statement is not entirely true. While plants do perform photosynthesis to generate energy in the form of glucose, they still require other substances to build all biomolecules. For example, plants need nitrogen from the soil to produce proteins and phosphorus for building DNA and other nucleic acids. Additionally, plants require various minerals and trace elements for proper growth and function. Hence, photosynthesis alone is not sufficient to provide all the necessary elements for building all biomolecules.
The four main types of biomolecules are carbohydrates, lipids, proteins, and(1 point)
nucleic acids.
