Select ALL substances that can be found dissolved in cell sap.

(1) Sugars

(2) Amino acids

(3) Proteins

(4) Pigments

(5) Toxic chemicals

Explanation

Vacuoles can contain a wide range of dissolved substances:

• Sugars, amino acids, and proteins - soluble organic compounds stored for metabolism
• Pigments - such as anthocyanins that give some flowers and fruits their red/purple color
• Toxic chemicals - many plant species store toxic compounds in vacuoles as a defense against being eaten; if the vacuole is ruptured (e.g., by a herbivore), the contents can harm the animal

Vacuoles do not produce ATP - that is the role of mitochondria.
