#environmental response

Plant signal transduction mechanisms may be relatively rapid or extremely slow (Figure 15.1)

When exposed to unfavorable environmental conditions, this complex interactive system adjusts homeostatically to minimize the negative impacts of stress and maintain metabolic equilibrium (Figure 24.1). (...) Under these conditions, the plant could compensate either by slowing down biosynthesis, thus reducing its growth rate, or by drawing on its stored food reserves in the form of starch (see Figure 24.1).
