Which is a function that roots DO NOT have?

• anchor the plant in place

• to make food

• absorb water and nutrients from the soil 

• store sugars and carbohydrates made by the leaves

Answer explanation

Roots DO NOT make food.

Plants make food in their leaves. The leaves contain a pigment called chlorophyll, which colors the leaves green. Chlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis.
