100
What gas enters the leaf for photysynthesis?
Carbon dioxide 
100
What are the green dots inside plant cells called?

To make food?
200
What part of the plant makes food using sunlight?
The leaves of the plant
200
What gas do plants take in during photosynthesis?
Carbon dioxide
200
What gas leaves the leaf after photosynthesis?
Oxygen
200
True or false: Animal cells have chloroplast.
False
200
What might happen if a plant does not get enough light?
It will not make enough food?
300
What structure helps transport water from roots to leaves?
The stem
300
What gas do plants release during photosynthesis?
Oxygen
300
How does water usually enter a plant?
Through the roots
300
What did scientist observe chloroplast doing under different lights?
Chloroplast moved inside the cell, either moving towards the light or avoiding it when light is too strong
300
How do plants help animals survive?
They provide oxygen and food
400
What tiny openings in leaves allow gases to move in and out?
The stomata
400
What sugar do plants make for energy?
Glucose 
400
Where does most gas exchange (one gas entering the plant, another gas leaving the plant) happen in a plant?
Leaves
400
Why do chloroplast move away from very strong light?
To avoid damage, the strong light damages the chloroplast
400
Where does the energy in the food we eat originally come from?
The sun
500
What structures inside plant cells capture light energy?
The chloroplast
500
What is the name of the process plants use to make their own food?
Photosynthesis 
500
What happens to matter (molecules) during photosynthesis?
Carbon dioxide and water are broken apart and rearranged to make oxygen and glucose.
500
Why do chloroplast move toward light in low light conditions? Include the name of the chemical reaction involving chloroplast.
To absorb more light for photosynthesis.

True or false. If all humans and ALL animals, everywhere died tomorrow, plants could still survive. Include your reasoning.
False. Humans and animals breathe out carbon dioxide. Plants need carbon dioxide to make sugar and oxygen. Plants need humans and animals.
