In science, the term "transport" refers to the movement of substances (such as water, nutrients, gases, and waste products) within living organisms and between different parts of an organism. This movement is essential for the survival and proper functioning of cells, tissues, and organs.
There are several mechanisms by which substances are transported within living organisms:
Plants require transport systems to move water, nutrients, and other substances between the roots, stems, leaves, and other parts of the plant. The two main transport systems in plants are:
Animals have specialized circulatory and respiratory systems to facilitate the transport of substances throughout their bodies. The circulatory system, including the heart, blood vessels, and blood, is responsible for transporting oxygen, nutrients, hormones, and waste products. The respiratory system facilitates the exchange of gases, allowing oxygen to enter the bloodstream and carbon dioxide to be removed from the body.
Here are some key concepts to focus on when studying the topic of transport:
Remember to review diagrams and illustrations that depict the processes of transport, as visual aids can help in understanding the complex mechanisms involved.
Good luck with your studies!
