The Different Adaptations
First, there is the pencil-like roots. Then there is the broad and waxy leaves and finally the drip tips. These are the various precautions or adaptations by plants to help them to adapt to the environment.
The Dragon's Scales
The Dragon's Scales, an epiphyte is a tiny and hardy fern. It is highly adapted for life on the branches of trees and paves the way for the establishment of other less hardy ferns.
Adaptation of Mangrove Trees
The pencil-like roots of the Avicennia branched upwards from the main horizontal roots that grow below the soil. These roots allow the absorbtion of atmospheric oxygen through specialized root cells known as lenticels. This adaptation is important, as mud that the mangrove trees grow extremely low in oxygen.
The Water Banana
The Water Banana bears two types of roots; those that look like bananas and those that anchor the plant to the soil.
The Rhizophora
The Rhizophora has roots that branch out from trunks like stilts. This helps to prop up the tree in the soft mud so that it will not topple with the ebbing and rising tide.
Bird Nest Fern
Asplenium nidus, also known as Bird Nest Fern is an epiphytic fern gaining foot hold on trees and rocks, often growing on the groung after falling from trees. The leaves can grow up to 1.4 metres long and form a nest-like rosette adapted to collect rainwater and trap nutrient rish debris and leaves falling from surrounding trees. Dead fronds remain on fern as a thick skirt beneath, ofter home to small animals and insects.
