Root caps are absent in

Step-by-step solution

The root cap's primary function is enhancing direct root growth by reducing friction against the soil, sensing gravity and protecting root meristem. In hydrophytes, the root system will be of a fibrous type and hence, the root pockets are present, whereas the root caps are absent, e.g., Eichhornia, Pistia, Lemna . Pandanus, Pothos and Ficus are plants that grow on soil.
