Modified Mangrove roots help it adapt to its environment

1]. Find an angiosperm that has modified roots

2]. Explain how this structural modification helped the plant adapt to its environment

Angiosperms (flowering plants) are the largest Phylum in the Plant Kingdom (Angiospermophyta is also called Anthophyta or Magnoliophyta). These plants have true roots, stems, leaves and flowers. The roots grow into the soil to anchor the plant in place and take up water and nutrients.

With these anatomical features in mind, do some research to find an angiosperm that has modified leaves, stems, roots or flowers that do not function in the normal manner, or that function in an unusual manner. Example: A California Barrel Cactus has spines in place of leaves to reduce water loss.

Explain how this structural modification helped the plant adapt to its environment. Make sure the plant you choose is an Angiosperm. For example, pine trees and mushrooms are not Angiosperms.

1]. A great example of adaptation is the Black Mangrove (Avicennia germinans). Like most plants, its roots are not photosynthetic and do not produce oxygen - this means they must obtain oxygen from the atmosphere. However, because Black Mangroves grow in tidal marshes these plants periodically have most of their root system covered by water, ...

Solution Summary

Anatomical aspects and environmental aspects of modifed roots are described using Black Mangrove as an example.
