Plant Transport
Where can water carrying tubes and food carrying tubes be found in a plant?
Water carrying tubes and food carrying tubes can be found in all parts of the plant.
How do fish breathe?
Fish take in water through their mouth and pass it across their gills. The gills remove dissolved oxygen from the water.
Where does the gas exchange process take place in plants?
The gas exchange takes place through tiny openings (stomata) in the leaves.
What are the different parts of the human respiratory system?
The human respiratory system consists of the nose, windpipe, lungs, and diaphragm.
Bonus: What are two characteristics of the air sacs (alveoli) in our lungs that help them to capture the most oxygen?
What is the most abundant gas in the air that we breathe?
Nitrogen is the most abundant gas in the air that we breathe.
In your group create a diagram/flowchart that shows how food moves through plants.
Drawing on board
What are two characteristics of gills that allow them to capture the most oxygen?
The shape of gills maximize surface area and are moist.
What gas do plants need to carry out photosynthesis and to break down food?
Plants need carbon dioxide to help carry out photosynthesis and to break down food.
What is the function of the human respiratory system?
The human respiratory system provides the body with oxygen and removes carbon dioxide.
What gases do humans inhale?
BONUS: What gases do we exhale?
In your group create a diagram/flowchart that shows how minerals move through plants.
Drawing on board.
What happens to the oxygen after it is absorbed by the gills?
The oxygen is transported through the blood to different parts of the fish where it is used to produce energy.
How do plants found below the surface in a pond or lake help fish and other animals that live underwater?
The plants produce oxygen for the fish.
Bonus 100pts: How do the fish and other animals benefit the plant?
What happens to the oxygen we inhale after it reaches our lungs?
The oxygen is absorbed into the bloodstream and transported throughout the body.
Water droplets (liquid) form when we breathe onto a mirror because the water vapor (gas) in our breath loses heat and condenses.
A student split a celery stalk in half and placed one side in a cup of red water and the other half in a cup of blue water. The stalk has leaves but no roots. What would the student see? Why?
Why is there a lot of blood present in the gills of fish?
There is a lot of blood in the gills because oxygen is absorbed into the blood and carbon dioxide is released from the blood.
In your group create a diagram/flowchart that shows how gases move through plants. (Think about gas going into, through, and then back out of plants)
Drawing on board
How are the human and fish respiration processes similar?
Fish and human respiration processes both take in and use oxygen while they produce and get rid of carbon dioxide.
If a grasshopper is placed in a box with no holes, explain what will happen to the amounts of nitrogen, oxygen, and carbon dioxide over time? (increase, decrease, stay the same, etc)
The amount of nitrogen will stay the same. The amount of oxygen will decrease. The amount of carbon dioxide will increase.
Bonus: Why does the carbon dioxide increase and the oxygen decrease?
What system in humans is similar to the plant transport system? Why?
The human circulatory system is similar to the plant transport system because it transports food, water, gases, and other substances around our body.
A student has a fish in a tank. The student measured the amount of oxygen in the water and realized their wasn't much oxygen for the fish. What could the student add to the tank to give the fish more oxygen?
The student could add water plants because they would produce oxygen for the fish.
What gas is produced when plants use carbon dioxide to break down sugars?
Oxygen is produced when plants use carbon dioxide to break down sugars.
What gas is produced by human cells when they burn oxygen to create energy?
Carbon dioxide is produced by human cells when they burn oxygen.
Bonus: What happens to the CO2 after it is produced by human cells?
How do the amounts of oxygen and carbon dioxide change from the air we inhale to the air we exhale?
There is more oxygen in the air we inhale than when we exhale. There is more carbon dioxide in the air we exhale than when we inhale.
BONUS: Why is there more carbon dioxide in the air we exhale?
