hye!! good evening!!
in plants, mass flow hypothesis is the concept for transport of sugar or food.
in animals, blood is the carrier to transport required energy molecules and gases

Transportation in animals
Transportation in animal takes place through circulatory system which includes blood, blood vessels and heart.
Blood is the red fluid which flows throughout the body and carries oxygen to all the cells of the body from the lungs and car bon dioxide from all the cells to the lungs.
Blood contains white blood cells, red blood cells, platelets and plasma.
Tube like structure through which carry blood to cells, tissues and organs are called as blood vessels.
Transportation in plants
In plants, it is only water and minerals that need to be transported to its other parts. Another thing that needs to be transported to other parts of the plants is the food prepared in leaves. This is because a plant has a branching shape so it gets carbon dioxide for photosynthesis and oxygen for respiration from air directly through diffusion.

The two types of conducting tissues that perform the function of transport system in plants are:
1) Xylem
2) Phloem
Transport of water and minerals
Plants need water to make food through the process of photosynthesis and minerals for making proteins. Thus, a plant absorbs water and minerals from soil through roots and transport it other parts like stem, leaves, flowers etc. It is through two kinds of elements of xylem tissue called, xylem vessels and tracheid that water and minerals move from roots of a plant to its leaves.
Xylem vessels
Xylem vessel is a long tube made up of dead cells joined end to end. It is a non-living tube which runs from roots of the plants and runs through the stem and reaches every leaf. The end walls of the cells are broken so that an open tube is formed.
Xylem vessels do not have cytoplasm or nuclei and the walls of the vessels are made of cellulose or lignin. Other than transporting water and minerals, xylem vessel also provides strength to the stem and keeps it upright. This is because lignin is very hard and strong. Wood is made of lignified xylem vessels. Xylem vessels have pits in their cell walls where lignin is not deposited. Either xylem vessel or both xylem vessel and tracheid transport water in flowering plants.
Tracheids
In non-flowering plants tracheids are the only water conducting tissues. Tracheids are dead cells with lignified walls with no open ends. They are long, thin and spindle shaped cells. They have pits in them and it is through pits only that water flows from one tracheid to another. All the plants have tracheid in them.
Two special blood vessels are arteries and veins.
After reaching the organs, the arteries divide in to small branches called as capillaries.
Heart in another component of circulatory system which is also known as pumping organ.
Heart consists of four chambers separated by a partition to avoid mixing of oxygenated and deoxygenated blood.
