Answer:
Stomata have two main functions, namely they allow for gas exchange acting as an entryway for carbon dioxide (CO2) and releasing the Oxygen (O2) that we breath. The other main function is regulating water movement through transpiration.
Answer:
Phylogenetic (evolutionary) Tree
showing the evolutionary relationships among various biological species or other entities that are believed to have a common ancestor.
• Each node is called a taxonomic unit.
• Internal nodes are generally called hypothetical
taxonomic units
• In a phylogenetic tree, each node with
descendants represents the most recent
common ancestor of the descendants, and the
• edge lengths (if present) correspond to time
estimates.
Explanation:
Phylogenetic trees are usually based on morphological or genetic homology. A comparison of anatomical traits can reveal an evolutionary relationship among species. Taxonomy, the science of classifying organisms, is based on phylogeny. Early taxonomic systems had no theoretical basis; organisms were grouped according to apparent similarity.
