• A group of similar cells doing the same job is called a TISSUE. Each
tissue perform a particular function within an organism.
• An ORGAN is made up of different type of tissues
• A group of organs working together make an ORGAN SYSTEM.

What different Organs Do You
Know?
Organ
• Add to your circle diagram the different
organ systems you know (underneath the
correct organ).
Organs
• An organ is made from a group of different tissues,
which all work together to do a particular job.
• Here are some examples of organs:
1. heart
2. lung
3. stomach
4. brain
5. leaf
6. root
You should be able to explain what
tissues and organs are (level 5)
Organ systems
• An organ system is made from a group of
different organs, which all work together to do a
particular job.
• Here are some examples of organ systems:
1. circulatory system
2. respiratory system
3. digestive system
4. nervous system
5. reproductive system
6. leaf canopy
