This means plants from John Cole’s Nursery are more likely to thrive in a new environment, having a stronger root base and higher tolerance to the elements. Hypodermis: It is the peripheral layer of cortex and composed of two to three layers of collenchyma. The roots of woody dicots and conifers develop only a cortex…. The notion that the root cortex of flowering plants that grow in aquatic or wetland environments under hypoxic conditions is comprised primarily of enlarged air spaces, or lacunae, has been considered for at least 150 years. Also multicellular plants are large so have a greater demand for substances. 66 ROOT-HAIRS The general structure of the root can best be studied in a cross-section through the mature region, the Creeping Buttercup [Ranunculus repens) furnishing suitable material for a first ex- ample.
