Plants and animals, both being living things, have an arrangement of physical structures that moves various substances all across their body. Such arrangement mainly acts as a transport system facilitating the movement of water, minerals, nutrients etc. that are crucial for the survival of that organism.
Plants have primarily two types of tissues that help transport water, minerals and nutrients. Those tissues are – xylem and phloem.
Xylem is responsible for transportation of water and mineral salts from the roots to different parts of a plant.
These tissues are made up of elongated dead cells and arranged as continuous vessels. Xylems are impermeable to water.
Phloem moves amino acids and sucrose between leaves and different parts of a plant.
These tissues are comprised of living cells which are arranged from one end to another end. It transports amino acids and sucrose up and down the plant. Phloems are different from xylems in this aspect.
Did You Know?
It is the stems that are responsible for transportation of water and nutrients in plants through xylem and phloem respectively. However, in one instance, there is a requirement of energy for movement and redundant in another instance.
The movement of water is unidirectional and takes place by way of adhesion and cohesion. This transportation is passive, that is, not requiring any energy whatsoever. On the other hand, the movement of nutrients from leaves to different parts of the plant requires energy.
Transportation in animals is the movement of food, water and oxygen to different parts of the body. Such a system is comprised of circulatory system and excretory system.
The main parts of the circulatory system are – blood, blood vessels and heart. Blood is pumped through two types of blood vessels, namely arteries and veins.
Arteries carry oxygenated blood from the heart to different parts of the body. Veins carry carbon dioxide infused blood from different organs of the body to its heart.
The Excretory system helps to eliminate the wastes generated in an animal body. The different parts of this system are – kidneys, urinary bladder, ureters and urethra.

1. Which Parts are Involved in Transportation in Plants?
Ans. Xylem and phloem tissues in plants are involved in the transportation of water and nutrients within a plant body.
2. Which Parts are Involved in Transportation in Animals?
Ans. Combination of the circulatory system and excretory system helps with transportation in an animal body.
What is the Major Difference Between Transportation in Plants and Animals?
Ans. In an animal body, the circulatory system is controlled by the heart. However, no such control is present over transportation in the plant body.
