One way plants store food and reproduce is with a structure called a corm.
Many corms produce two different types of roots. Familiar fibrous roots anchor the plant in the soil and absorb water and nutrients. Contractile roots pull corms deeper into the soil, away from animals and extreme temperatures. Contractile roots stop pulling the plant downward as conditions above improve.
