1. Respiration in Living Organisms

2. All Kingdoms: Cellular Respiration
EVERY organism completes the process above
Occurs in the mitochondria of cells

3. Kingdom Protista: Respiration
Simple Diffusion
Draw the picture of the protist to the right
Identify the protist
Draw a blue arrow going into the protist and label it oxygen
Draw a red arrow going out of the protist and label it carbon dioxide

4. Kingdom Plantae: Respiration
Exchange gas through tiny air pores, or openings, called stomata
Guard cells control the size of the stomata

5. Kingdom Plantae: Respiration
Use this image to label the cross section of a leaf on your paper
Color the guard cells green
Draw a red arrow going into the leaf labeled carbon dioxide
Draw a blue arrow coming out of the leaf labeled oxygen and water
Top of vein: Phloem
Bottom of vein: Xylem

6. Kingdom Plantae: Stomata Lab
Follow the directions for the lab given by your teacher
Answer the questions once you have finished

7. Kingdom Animalia: Respiration
Label and describe each picture with the correct respiratory system using the table on the next slide
Highlight the areas on each organism that represent their respiratory system
Go to a dissection lab station
Try to identify the respiratory system on the crayfish and the grasshopper

8. Kingdom Animalia: Respiration
Organism
Respiratory System
Aquatic Animals
Gills- specialized slits that contain blood vessels to dissolve oxygen
Earthworms and frogs
Skin- must live in a moist environment to maintain a surface oxygen can naturally diffuse through
Insects
Spiracles- tiny openings on the abdomen that allow gases to be exchanged
Humans
Lungs- sponge-like organs with tiny balloon sacs called alveoli which allow gas to be exchanged into blood vessels
