The table shows the derived traits of five plant groups. Which trait was the earliest to appear among the plant groups ??

A. Flowers

B. Seeds

C. Stomata

D. Vasculature

C. Stomata

Explanation:

Over time, related groups diverge from a common ancestor through the process of evolution. Certain groups develop characteristics in response to specific environmental changes and become increasingly more genetically distinct.

These characteristics, called adaptations, ensure the survival of organisms and their offspring which best suit their surroundings. Through phylogeny, these changes are studied and mapped through genetic analysis in phylogenetics. Noting trends derived from the study of these groups, it can be seen that the most common traits are derived from a common ancestor.

In plants, stomata are regions that allow for gaseous exchange; they are seen in the most simple plant systems, where gases may readily diffuse through the cells of the organisms.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
