Trees grow lush green leaves in the spring, but they all fall out when it gets closer to winter
Answer: C. The species is classified in a clade that does not include all protists.
The Kingdom Protists involves organisms which are simple in structure and functions. Some of these organisms have characteristics common to both plants and animals. A clade represents a group of organisms that have all characteristics common to their ancestor. The example of algea given here, has characteristics which are found mainly in plants belongs to Kingdom Plantea. Therefore, the clade of these Protists can be related with those of plants but cannot be related to Protists which exhibit animal like characteristics.
Therefore, species is classified in a clade that does not include all Protists.
Algae are photosynthetic, but they are also unicellular organisms (Euglena) and shares some of the common features with plants as well as animals. They move like animals and perform photosynthesis like plants. Therefore, they are classified into Protists, and not the Algae. Their most features resemble the non-photosynthetic protozoa, and not plants, and therefore, are put into the Protista.
They also lack a cell wall, which is a feature of plants.
Some scientists advocate their classification in plants because of their sexual mode of reproductiona, and formation of spores.
