All plants have characteristics
that allow them to survive in
their particular habitats. Plants
such as the samphire (top right)
and Seablite (top) are exposed
to frequent flooding. This flooding causes salt to accumulate and
harm plants. But special salt glands in these plants prevent them
being damaged. Salt marsh plants such as the glasswort survive
thanks to their leaves on the water surface. In plants such as the
water lily (opposite page) and Elodea (below), oxygen is transmit-
ted from the stem and leaves above the water, to the underwater
portions.
