To adapt to the environment they are in.
Example:
No, onions are not an example of plants with modified roots. Onions have a bulb which is a modified stem, not modified roots. Examples of plants with modified roots include carrot and radish.
To adapt to the environment they are in.Example:Some cacti have their roots deep in the ground, to get groundwater.Some cacti have their roots spread out, to catch rainwater. Their roots also secrete an acid that makes it difficult for other plants (including other cacti) to grow on those roots. This limits the competition for water.
examples of plants with modified roots.....
Stolons are not modified roots; they are specialized above-ground stems that grow horizontally and produce new plants at nodes along their length. Stolons help plants spread and reproduce asexually by producing new offspring at various points.
Cactus plants hold water temporarily in their roots. They also hold it temporarily on their modified leaves. They hold it permanently in their stems.
Not all plants have roots (eg phytoplankton) and while some plants do grow form their roots (eg grasses), most plants do not grow from their roots but from their apical growing tip.
No, not all plants possess roots. Some plants, like mosses and ferns, do not have true roots but instead have structures that serve a similar function.
Modified roots are roots which change their structures to carry out vital functions such as photosynthesis, gather oxygen, store food or water, or support the stem.BIBLIOGRAPHY FROM URL:http://www.tutorvista.com/biology/modified-rootsHoped I helped!
Plants roots that are above ground are called aerial roots. Examples are some types of orchids, mangroves, and banyon trees.
Grasses have fibrous roots, with some branching out rhizome roots to produce young plants.
