Comparing Transport Systems in flowering Plants and Mammals
Unit 2 Biology- FUNCTIONING ORGANISMS"Transport systems play an essential role in the survival of flowering plants and mammals" Transport systems play an essential role in the survival of flowering plants and mammals. These organisms rely entirely on the transport of water, oxygen and nutrients to every cell. To supply these products at a rate the organisms demand to sustain life, they have developed a specialised transport system. Simple diffusion from the organism's surface to their inside would just be too slow because of mammal and flowering plant's small surface area in comparison to it's volume. The transport system in mammals and plants is relatively similar as they transport materials through specialised tubes, and use water as a basis for transport due to its ideal properties. Mammals 'tubes' are known as blood vessels and form a circulatory vascular system. Blood vessels are elastic tubes that carry blood from the heart, distribute it through the body, and return it back to the heart. The blood vessels that transport blood away from the heart are the arteries which are the largest in size of the vessels. These divide into smaller arteries (arterioles), which then divide into m
Xylem and phloem transport solutions through their vessels as do mammals with their blood vessels. Transport in phloem (translocation) is more closely related to the transport in the mammalian vascular system, as they control transport according to their metabolic needs by increasing or decreasing. Xylem of plants carries water and mineral ions whereas phloem carries a solution of sucrose produced in photosynthesis and contains other essential products such as amino acids, fatty acids, glycerol, minerals such as nitrate and phosphate and hormones such as gibberlins. ATP is a form of energy required in both mammals and plants. Mammals need ATP to pump the heart and contraction of muscles around vessels to push blood to the heart. Plants need ATP in the phloem as it's required for active transport (against a concentration gradient) and for generating root pressure in the xylem. In mammals, the job of the circulatory system is to transport blood to all the cells in the body. The blood is the liquid transporting nutrients from the digestive system to the tissues, and wastes from the tissues to the urinary system as part of the plasma. Plasma is the liquid comprising 55% of blood. 45% of the blood is the solid section containing red blood cells, white blood cells and platelets. This section of blood tr
