People without Plants

Biology

When a person goes into the rainforest or the ocean, that person can readily notice that the rainforest and the ocean are teeming with life. An observer of these places will also notice how every form of life works together to sustain the environment. Though human beings build artificial environments such as cities, humans are a part of the ecosystem on Earth, and they participate in this co-dependency on other forms of life to survive as well as to sustain the environment. A form of life that humans are dependent on are plants. Without plants, human beings would have no air to breathe and their respiratory systems would fail. There would exist no human civilizations without oxygen. Perhaps there would be other forms of life in the place of humanity that breathed another gas, but humanity would not exist as we know it today were it not for the existence of plants.

Plants are structured or designed to intake carbon dioxide, what humans exhale, and by a process known as photosynthesis, expel oxygen, which humans inhale. The process begins with the absorption of sunlight through the leaf cuticle.The light encounter mesophyll and chloloplasts. Molecules absorb chlorophyll, gaining excitation energy, synthesizing carbohydrates, and eventually producing organic molecules into the atmosphere, such as oxygen. The plants use carbon dioxide and convert it into sugars. All forms of life and processes such as photosynthesis are dependent on the sun. The sun is responsible for all life on Earth, as well as for wind, the planet's magnetic field, gravity, and rotation. Plants take the energy gathered from sunlight and by the process of photosynthesis, produce a gas that is critical to human survival. The act of breathing in humans produces a gas that is critical to plant survival. In this way, it is clear that the codependence of plants and humans to live exists on a very basic level. There are many ways in which plants enrich the life of human beings, yet it begins on a fundamental level that plants and humans depend on each other for the breath of life.

The uses for plants in human life are old and are….....
