Transport of materials is necessary in both plants and animals as every cell needs a regular supply of nutrients and oxygen for releasing energy through respiration. ... The oxygen that we inhale is also transported to all the cells of the body.

Why do plants need to transport materials?
For the process of photosynthesis, raw materials should be transported to the leaves. For transport in plants, they need a transport system to move food, water, and minerals around because for them no heart, no blood, and since these plants do not have a circulatory system, transportation makes up for it.
Why plants and animals need a transportation system Class 7?
Transportation of substances
To perform these functions, every cell in the plant and animal body require useful substances such as nutrients, oxygen and water. Plants and animals have a transport system to carry useful substance to every cell of the body and for the removal of waste material produced by the body.
What is transport system in plants and animals?
Transport in both plants and mammals is by a system of specialised tubes. ... In mammals this forms a circulatory system of arteries, capillaries and veins. In flowering plants, transport is not circulatory and occurs in microscopic xylem and phloem.
Why is transportation necessary?
Transportation is needed because few economic resources—raw materials, fuels, food, manufactured goods—are located where they are wanted. ... Through transportation, goods are moved from where there are surpluses to where there are shortages.
Why do animals need a transport system?
As the size of an organism increases, its surface area to volume ratio decreases. ... Large multicellular organisms therefore cannot rely on diffusion alone to supply their cells with substances such as food and oxygen and to remove waste products. Large multicellular organisms require specialised transport systems.
What is the need of transportation in animals?
All the organisms need to transport water, food, minerals, oxygen to different parts of the body. They help in the growth and respiration of the cells. The waste products are transported to the excretory organs for elimination from the body.
How do plants transport materials?
Plants have tissues to transport water, nutrients and minerals. Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids between the leaves and other parts of the plant.
What is plant transport system?
Plants have two transport systems - xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.
Why is transport system in animals is more complicated than plants?
Animals are more complex creatures and require more food and nutrients because they are able to move about. ... Once nutrients are broken down by the digestive system and are absorbed, they need to be distributed to various organs and tissues in the body to replace energy being expended.
Why transportation of material in plants is necessary and which elements help in this process?
Transportation in plants is a vital process to circulate water, essential nutrients, excretory products and gases within the plant for various purposes. Transportation in plants is mainly brought about by vascular tissues. Vascular tissues are the conducting tissues formed by xylem and phloem in plants.
How does transportation help plants?
Transportation is a vital process in plants. Trees transport all the nutrients and water it needs for survival from its roots to the tips of the leaves. ... Similar to the circulatory system in humans, the xylem and phloem tissues extend throughout the plant.
Why do plants transport water and minerals?
Ans. Water and minerals are transported in plants with the help of xylem tissue. Roots absorb the water from the soil by actively taking up ions, creates the difference in the concentration of these ions between the root and the soil. ... It creates a suction pull, which pulls water from the xylem cells of roots.
Why higher animals need an internal transport system?
The higher animals need an internal transport system so that the innermost cells can get nutrients which cannot be left on diffusion and osmosis to transmit. They also need an internal transport system so that they get oxygen to the inner cells.
Why transport system in plants is not as elaborate as in animals?
Answer: Transport system in plants is less elaborate than in animals (including human beings). Plants are less active, so their cells do not need to be supplied with materials so quickly. ... (ii) Transport of food and other substances (like hormones) in the plant.
