Chloroplasts Photosynthetic and plant-like in structure Photosynthetic and single-celled Immobile and mixotrophicarrow_forwardPhylogeny refers to the evolutionary descent of taxa. It refers to the relationship between ancestors and descendants and relationships among descendant taxa. It shows the lineage of taxa which can be summarized in a branching diagram called a phylogenetic tree.1. Express some basic evolutionary relationships among groups of microorganisms, plants, and animals; 2. Illustrate the relationship of organisms with their environment; and 3. Analyze environmental factors contributing to biodiversity richness and lossarrow_forwardWhen constructing phylogenetic trees, Biologists often adhere to the principle of "maximum parsimony". This means that; Scientists should not include an outgroup when constructing their trees Scientists rarely use DNA to construct phylogenetic trees The phylogenetic tree that is involves the fewest changes is probably correct Scientists do not use homologous characteristics in their treesarrow_forward
