Question
Over millions of years plants have adapted their structure to survive in their environment. Consider the following structures and describe what problems they solve for the plant. a) Dandelions have long tap roots b) Milkweed seeds are light and feathery ( 2 bonus marks )0 pointsYour answer
Solution
a) Dandelions have long tap roots: The long tap roots of dandelions help them to solve several problems. Firstly, these roots can reach deep into the soil to access water and nutrients that are not available on the surface. This allows dandelions to survive in dry conditions where other plants might struggle. Secondly, the long tap root also anchors the plant firmly into the ground, protecting it from being uprooted by wind or other disturbances. Lastly, even if the above-ground part of the dandelion is removed or damaged, the tap root can regrow the entire plant, aiding in its survival and propagation.
b) Milkweed seeds are light and feathery: The light and feathery structure of milkweed seeds helps them to solve the problem of dispersal. Being light and feathery, these seeds can be carried away by the wind over long distances. This allows the plant to spread its offspring far and wide, increasing its chances of finding a suitable place to germinate and grow. This also helps the plant to colonize new areas and avoid competition with parent plants for resources.
