StemStems do many things. They support the plant. They act like the plant's plumbing system, conducting water and nutrients from the roots and food in the form of glucose from the leaves to other plant parts. Stems can be herbaceous like the bendable stem of a daisy or woody like the trunk of an oak tree.
"Like a straw", transports water through plant. Raises the height of flowers and leaves. Brings closer to light. Structural. The stem is made up of little tubes. These support the upper parts of plants. Water and dissolved nutrients from the soil travel up the stem in a system of tubes. Food from the leaves travel down stems to the roots. Stems also store food for the plant. |
