Connecting the Pieces
100
What do you call a molecule found in food?
A food molecule.
100
What was M'Kenna's condition?
Celiac disease
100
What part of the plant is found below the ground?
The roots
100
What is made during photosynthesis?
Glucose and oxygen
100
Why do we eat plants?
To gain food molecules.
200
What food molecules are made of mainly carbon, hydrogen and oxygen atoms? (glucose, starch and fiber)
Carbohydrates
200
What did M'Kenna's condition cause her body to not do?
Her body could not absorb glucose in her small intestine.
200
What part(s) of the plant are found above the ground?
Leaves and stems
200
What are the ingredients of photosynthesis?
Carbon dioxide, water and sunlight
200
What is compost?
Dead things being broken down.
300
What is the smallest carbohydrate?
Glucose
300
What food molecule cannot be broken down in our bodies?
Fiber
300
Where are chloroplasts found in the plant?
They are found in the leaves.
300
What happens to photosynthesis if there is no sunlight?
It does not happen.
300
Why are dead things so important for plants?
They provide them with nutrients not easily obtained.
400
What is the largest carbohydrate?
Fiber
400
What part of the body absorbs glucose? (Be specific.)
The villi
400
Where are the stomata found in the plant?
They are found in the leaves.
400
Where does photosynthesis happen in the plant? (Be as specific as possible and use the scientific name.)
In the chloroplasts.
400
What other atoms did we say are in food molecules other than carbon, oxygen and hydrogen.
Nitrogen and sulfur
500
How do plants get their food?
They must make it using carbon dioxide, water and sunlight.
500
How is glucose transported throughout our bodies?
Through our blood.
500
What is the function of the chloroplasts?
To conduct photosynthesis.
500
Why is carbon dioxide needed for photosynthesis?
The carbon in the molecule is needed to make glucose.
500
How do animals help plants?
We breath out carbon dioxide and our excretion has important nutrients in it.
600
What food molecules is found in maple syrup?
Glucose
600
What gas is needed to burn glucose or fat?
Oxygen
600
What is the function of the stomata?
To breath in carbon dioxide and breath out oxygen.
600
Why is sunlight needed for photosynthesis?
The energy from the light is needed to start the chemical reaction.
600
How do plants help animals?
They take carbon dioxide out of the air, create food and absorb other materials which are harmful in large amounts.
700
What function does the maple sap serve for the maple tree?
The maple sap is what transports food molecules throughout the plant.
700
What gas is produced from burning glucose or fat?
Carbon dioxide
700
How do chloroplasts respond to low light conditions?
They move away from the light.
700
What happens to photosynthesis if there is no carbon dioxide?
Oxygen can still be made but glucose cannot.
700
If plants need nitrogen to make protein, why are they not absorbing it from the air?
They cannot use nitrogen in gas form, it must be a liquid.
800
What is the function of food for plants?
It is stored food for the plant to use later. Just like how our bodies use fat.
800
What is the name of the process where our bodies burn glucose or fat to gain energy?
Cellular respiration
800
Why do chloroplasts move away from sunlight in intense light conditions?
They can get burned and die.
800
How does the energy from the light start the chemical reaction for photosynthesis?
It gives the carbon dioxide and water molecules the energy they need to break apart so they can regroup as glucose and oxygen.
800
What do you notice about this equation and what we have learned about previously?
Photosynthesis is cellular respiration but backwards.
