Write a 3-5 paragraphs and include examples to support your answer

Prompt #2: Plants and animals are very different in form and structure and function. However, both plants and animals utilize similar basic principles for circulation and gas exchange. Compare and contrast circulatory systems in plants and animals. What mechanisms are used for circulation? Gas exchange? How are wastes removed? Describe how the surface area to volume ratio is important for circulation and gas exchange in both plants and animals. Feel free to include drawings/diagrams to supplement your discussion.

Ans-

               Animals circulatory system consists of the heart, arteries, capillaries, veins and blood where heart pumps that push the blood to the arteries and veins. After distribution of nutrients, the blood moves to veins and takes with it waste products such as carbon dioxide and other chemical waste products that remove through proper excreted organs. For transport the substances such as respiratory gases, glucose, amino acids, fatty acids, glycerol, vitamins, minerals, and hormones they use water as a medium.
                     Compared to animals, plants circulatory system consist of xylem vessels and tracheids and phloem sieve tubes. There is a no pumping mechanism and use water as a medium to transport the substances such as sucrose, amino acids, fatty acids, glycerol, vitamins, hormones (in the phloem) and minerals and water (in the xylem). The movement of water takes place through capillary pressure. Waste products such as carbon dioxide and water produced during cellular respiration are excreted through stomatal spores.

               The small organism has large surface area to volume ration and all the nutrients and respiratory gases are transported through diffusion. Most plants and animals have a too small surface area to volume ratio, so diffusion process unable to provide the required molecules. Hence, they require a system to carry nutrients and waste products throughout the body.
