Embryophyta is a clade within the Phragmoplastophyta, a larger clade that also includes several green algae groups. Embryophytes are the plants growing on land which include hornworts, liverworts, gymnosperms, flowering plants etc while green algae mostly thrive in aquatic environment.
The conduction of water requires vascular tissue called xylem. In green algae, it is not necessary to have water conducting tissue as the entire body is in contact with water. However in embryophytes, having a vascular tissue is an adaptation that ensures to provide water to the higher parts of the plant which is not directly in contact with the soil.
Wait no i know what it is its the Liverwort. Yes its that.
Explanation:
Natural selection is the mechanism that is responsible for the evolution of organisms.
In the given case, the Freshwater shrimp has been introduced to a pond in which the two species with variations are introduced.
The <em>C. cantonensis </em>is brighter in color whereas the <em>C. multidentata</em> is mottled drab in color. The predator fish can feed easily on the species which is brighter therefore <em>C. cantonensis</em> is more susceptible. The mottled drab species is not easily predated by the species.
The 30 % offsprings of <em>C. cantonensis</em> can survive till the reproductive age whereas 75% of C. multidentata. This shows that natural selection has acted on the color of the shrimp species selected against the predator fish species.
The species with mottled drab color is the result of the differential reproductive rate.
