AP Biology Essay #7 concerning Evolution, created using the grading rubric, so will be an A+

discuss the evolutionary relationships between the two members of each duette you halt chosen. In your discussion include structural adaptations and their in operation(p) significance. a. Green algae...vascular Plants b. Prokaryotes....Eukaryotes a. Green alga and Vascular Plants cast off pardon evolutionary relationships. Both Green algae and vascular plants have many similarities displaying this fact. Just a hardly a(prenominal) of these similarities include that both groups have chloroplasts with chlorophyll b and beta-carotene (for get fodder), chloroplasts of similar grammatical construction, chemically similar cellulose in cell wall, similar peroxismes (which contain enzymes), alike Mitosis and cytokinesis processes (reproduction), similar sperm ultrastructure, and similar rRNA structure (shows relation at a genetic level). These two structures do of passage differ, because the vascular plants are much further evolved than the Algae. A hardly a(prenomin al) of these likely acquired traits are Xylem, and phloem, which transport both pissing and food throughout the plant much like the veins in our trunk transport oxygen through veins and arteries, though Xylem unconnected Phloem use passive transport to accomplish this. The cuticle, or pliable covering of the vascular plants, allowing them to survive perhaps better, particularly when supplied with less(prenominal) water, helps prevent evaporation of water from the vascular plants, allowing them to elicit comfortably away from shallow water, which much of the algae appear on. on that point are many other evolved traits which the vascular plants experience as well.

Though there are differences, clearly Green Algae has an evolutionary relationship to Green Algae. The multiple structural similarities, and advancements of the vascular plants clearly show Vascular plants have a buoyant close evolutionary relationship with Greene Algae. b. Prokaryotes, and Eukaryotes also share evolutionary relationships. Basic similarities between these organisms include, having nucleic acids (genetic connection), Chromosome(s), possession of ribosomes( site for creating of polypeptides), having cell membranes and walls (protection and structure), reproduction...
