Evolutionary Change
Throughout the course of life evolution has taken its place on plants and animals. One of the greatest evolutionary changes was the transition of life in water, to the transition to life on land. As you can imagine, both organisms had challenges moving from this single cellular water environment to a multi-cellular land environment. While the change was difficult, this new environment would help organisms flourish in life, giving them the ability to reproduce more freely, and eat with less competition in their habitat. With moving, animals had to learn to adapt to their new environments. With the help of evolution, these organisms had to deal with a change in structural support, a new form of respiration, the prevention of water loss, and

Since animals lived in water, they relied on their structure of gills. The structure of gills allowed these marine animals to capture oxygen out of the water and expel carbon dioxide as well. Transitioning onto terrestrial environments meant that these animals would need evolve their respiratory system. Primarily, the heart and circulatory system underwent these evolutionary changes to enhance the amount of oxygen they can take in. In order for an animal to thrive it must be able to perform various amounts of actions. With this new respiratory system, larger muscles meant a larger intake of oxygen, allowing animals to perform greater actions, and roam further places. Moisture also plays a vital role in respiration because it helps oxygen pass through their skin and blood, helping animals breathe. Respiration in marine plants was a much more difficult transition than the transition of animals. Plants, such as algae, used diffusion. This process allows the algae to obtain a sufficient amount of carbon dioxide. During their transition to land, plants still demanded a higher amount of oxygen. To do this, plants evolved a stomata, which is like a mouth-shaped opening. The stomata regulated gas diffusion which allowed for plants to get their appropriate amount. The stomata is capable of opening and closing to regulate gas exchange since it has limitations that the cuticle carries
