Both plant and animal circulatory systems transport nutrients to cells to keep them alive. In animals, the heart pumps blood through vessels to deliver sugars. In plants, xylem draws water and minerals up from the roots and phloem transports sugars made in the leaves throughout the plant. While both systems supply cells, plants have a two-way vascular system and produce their own food, whereas animals rely on consuming food for nutrients and have a one-way circulatory system.

1. Animal and Plant systems
How similar are they??

2. Animal circulatory system
• Heart pumps blood
• Blood goes through blood vessels
Veins
Artieries
Caplillaries
The blood carries nutrients (sugars) to all of the cells
of the body

3. Circulatory System
• How it works

4. Plant Vascular System
• Roots suck up water and minerals through
tubes called the xylem
• The xylem carries water and minerals up to
the leaves
• The plant creates food (sugar) in the leaves
• The phloem carries the sugar throughout the
plant to deliver sugar to all of the cells

5. How do Plants make food?

6. Similarities
Plants
• Plant cells need nutrients
(sugars) to stay alive
• Systems of vessels carry
nutrients throughout the
plant to all of the cells
Animals
• Animal cells need nutrients
(sugars) to stay alive.
• A System of vessels carry
nutrients throughout the
body to all of the animal
cells.

7. Differences
Plants
• Plant vessels are a TWO
way system.
• Xylem goes up
• Phloem goes down
• Plants create their own
nutrients (sap)
Animals
• Animals have ONE closed
system that never ends.
• The blood circulates
throughout the body over
and over again through
arteries, capillaries and
veins.
• Animals have to eat in order
to get their nutrients.
