1. Lesson Starter What is the job of the nerve cell?
What is special about the nerve cell?

2. Lesson 11- Cell Organisation
Cells Alive
Lesson 11- Cell Organisation

3. Today we are going to..
Learn how all the different cells in our bodies are organised

4. Unicellular Organisms
Some organisms are only made up of one cell
Amoeba has everything they need within their one cell to survive

5. Multicellular Organisms
Multicellular organisms are made of 2 or more cells:
What multicellular organisms can you think of?

6. Multicellular organisms

7. Cell Organisation
There are many different types of cells (adapted cells) in a multicellular organism
In large multi-cellular organisms (like humans), groups of adapted cells can work together in order to carry out the same job- this is called a TISSUE
Tissues then join together in order to make an organ
Cells Tissues Organs

13. Body systems
Our organs all work together in a body system There are lots of different systems in our body! With the person next to you, try and come up with as many as you can!

14. Nervous system The nervous system consists of your: Nerves Spinal cord
Brain
Electrical impulses (messages) are sent from the brain (or spinal cord) to the nerves.

15. Digestive System
The digestive system consists of the mouth, oesophagus, stomach, intestines and anus
Food enters through the mouth and follows the digestive pathway until leaving the body as waste

16. Respiratory System The respiratory system consists of the: Lungs
Trachea (windpipe)
Associated blood vessels
Oxygen is breathed in and carbon dioxide released

17. Circulatory System The circulatory system consists of: The heart
Blood vessels
Blood is circulated throughout the body carrying the nutrients needed.

18. Whole Organism
The different systems in our bodies work together in order to form a WHOLE ORGANISM
Cells Tissues Organs Systems Organism

19. Plants also have organs and systems

20. Plants
The root
Takes in water and nutrients from the soil to help the plant grow. Also ANCHORS the plant.
