If we understand these plant structures we understand how to grow plants .Plants are necessary in that they are the basis for everything else. We either eat plants, or we eat things that eat plants.

This article from Khan academy gives a brief overview of the different processed involved in cellular respiration. This is the production of energy that runs the world from just sunlight and Co2 we feed the world fromthis one process.

"Adaptation and Survival." National Geographic, education.nationalgeographic.org/. Accessed 3 Feb. 2024.

This explores why some organisms are more successful than others. Any advantages a plant has that it can pass on to its offspring helps it survive . I read a great article Wyatt, Robert E. "Plant Life on Granite Outcrop." New Georgia Encyclopedia, 23 Dec. 2004, www.georgiaencyclopedia.org/. Accessed 3 Feb. 2024. and it explores the adaptations that certain plants have made to thrive in a niche enviroment, These include the Georgia oak (Quercus georgiana), the loblolly pine (Pinus taeda), and the short leaf pine who have adapted to be drought resistant,and they "reign supreme"on rocky outcrops as Robert Wyatt puts it.

This is from Libre Texts Biology 8.2: Terrestrial Biomes a secttion of the larger text on Biomes. In the 1930s during the dust bowl, People intentionally planted kudzu(native to China) to control erosion. Kudzu has no natural predation. The reason its not invasive in China is it is widely used and harvested .In a similar biome with nothing to slow it down it takes over and does a lot of damage.

This is an interesting article from thoughtco about the domestication of cotton. Cotton is one of the earliest non food plants that was domesticated. Cotton and its many varieties have been grown around the world for at least 6 to 7 thousand years. At least 4 independent times and places cotton has been discovered.

The four domesticated Gossypium species of the Malvaceae family are G. arboreum L., domesticated in the Indus Valley of Pakistan and India; G. herbaceum L. from Arabia and Syria; G. hirsutum from Mesoamerica; and G. barbadense from South America. Cotton was used in ropes and nets as well as clothing. Cotton was important because it was cheaper although not as durable as flax(linen).

The diagram is of the pathogen that caused the potato famine in Ireland. The potatos were adapted because they were caloricly more dense than wheat and were easy to grow not just in farms but in your garden. People ate the potatoes and a third of potatoes grown were also fed to cattle . People ate between 40 and 60 potatoes a day and were so reliant on potatoes that when the blight hit millions of people starved and this triggered waves of human migration from Ireland to America.

This illustrates the danger of society being dependent on one, or a few different foods as we are dependent on wheat which makes us vulnerable in case of wheat blight.

The history of medicinal plants and their uses by the national Institutes of health . This article highlights plants that have historically been used as medicine by different cultures around the world. This is important as it lets us keep a historical and cultural history alive when we remember historically what has been used. These medicines (plants) can be be protected and kept safe for future generations. These are medicines that we can sustainably use for future generations by using sustainable methods of growing and harvesting.With new technology there may be new medicines available from what we had used historically.

Indigenous knowledge is essential to recognize valuable plant assests and protect them for future use.We look for the essential thing and we may dismiss indigenous knowledge as unimportant, or we dismiss it because we don't have a current use for the information. As climate change progresses it will affect plant growth and production. The need to protect the plant biodiversity will increase as climate change increases. We cannot anticipate every future contingency which is why it is important to protect the indigenous knowledge and the plants.
