Answer:
The correct option is A.
Convergent evolution is one of the defined type of evolution and it is shown by the species belonging to different ancestors show similar characteristics due to the same residing environmental condition.
Explanation:
The creation of analogous structure takes place in the process of convergent evolution. This is illustrated by the occurrence of similar structure in two different species which were not observed in their respective ancestor. This is due to the residence of the associated species in the same environmental condition and facing the same problems of livelihood. One of the most common example is the flying ability of the insects, bats and birds.
The conductive tissues of the angiosperms are the xylem which drives the raw sap and the phloem which conducts the elaborate sap.The phloem, or liber, drives the elaborate sap, solution of organic substances rich in carbohydrates, from the leaves to the other organs.
The elaborate sap (which contains organic substances produces by photosynthesis) is produced in the leaves, where the majority of the chlorophyll subsist, so if the leave die off, the production of organic substances and the elaborate sap are reduced, so its transport by the phloem will be reduced, and this is how the phloem will be affected by the dying of the leaves.
Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. For example, a rabbit can't choose to have a different fur color.

Answer:
Seed dispersal is the movement, spread or transport of seeds away from the parent plant.Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire.
