In any living organism or thing, the circulatory system plays a significant role in ensuring the delivery of oxygen, water and food among other important substances. The circulatory system is also charged with the duty to remove waste products from the body of the living organism. With this in mind, plants and humans have a number of similarities and differences in relation to their respective circulatory systems. This paper seeks to explore the various similarities and differences in order to draw a comprehensive comparison. Additionally, the paper highlights in the significance of plants to human life.
The first similarity is that both circulatory systems are organized into tube like structures through which dissolved substances flows. In plants, the tubular connective tissues are known as the phloem and the xylem as compared to veins and capillaries (for instance) in humans.
The transfer of materials from one region to another through the cell membrane is facilitated by processes of osmosis, active transport and diffusion (Jrank.org., 2012).
These circulatory systems work to deliver water and dissolved nutrients to different parts of the organism. The systems are organized into an efficient and comprehensive network to ensure that all organs of the organism are nourished. In relation to this particular similarity, the respective tubes are organized into two main and different directions. The phloem and xylem exists in plants while veins and arteries are found in humans.
These circulatory systems are different in the following ways. In general, plants have a less complex circulatory/transport system as compared to humans (Johnson, 2012). The human circulatory system depends on the pumping mechanism of the heart to ensure that nutrients reach the intended destination within the body of the human being. On the other hand, plants rely on gravitational pull and water surface tension.
The plant circulatory system is known to only transport water solutions from one region to another unlike the human circulatory system that contains living cells like white and red blood cells that move along with dissolved substances.
Plants play various important roles to humans. This group of living things is very significant. This following is a list of those benefits. This is how Ellison Chair in International Floriculture (n.d.) has broken them down.
- A simple benefit of plants is that they help people to concentrate within their respective environments whether at their work places of homes.
- Homes and workplaces for decorations to achieve the desired ornamental value. Flowers are known to effortlessly generate happiness.
- Various plants across the globe are used for nutrition, as food. Processed foods have become household names. An aspect of value addition has been achieved since processed foods are more expensive in the market.
- Plants act as catchment area to attract or enhance formation of rain
- Plants are used for medicinal purposes. Various cultures around the still rely on the forests to develop herbal medicine.
- Plants are used prevent destructive natural processes like soil erosion. Plants (trees) are known to stabilize the soil around them thus reducing the force of moving water.
- Plants are used for recreational purposes for instance forest in national parks. This very plants in turn act as shelter for animals and birds with that national park
- In the medical world, plants are known to contribute to a faster healing rate of a patient.
- Parks are known to enhance cohesion of the community in addition to lowering the crime rate in that community. As people walk through a park they randomly interact thus a good opportunity to bring people together.
- Plants are planted along roads to improve the satisfaction of drivers in addition to creating a beautiful landscape to road users.
In conclusion, these few remarks clearly reveal how we cannot do without plants. With this in mind, I assert that it our duty to protect plants by conserving the environment.
