7. We are unable to live without plants. What do they provide for us to be able to stay alive? List 2 items and
name the process by which they produce them.
Plants make oxygen and glucose that we need to stay alive. They make it by photosynthesis.
8. Plants are unable to live without us. What do we provide for them to be able to stay alive? List 2 items and
name the process by which we produce them.
We make carbon dioxide and water. We make them by cellular respiration. Plants need carbon
dioxide and water to stay alive
9. Water is a basic need of all living things, however it is a waste product of cellular respiration. What evidence can
we use to say that we get rid of water as a waste product of respiration?
We breathe water out when we do cellular respiration. We can tell because we breathe out moisture.
It can be shown by breathing fog onto a mirror or a pair of glasses.
10. Draw a molecule of each of the following.
d. Water
e. Carbon dioxide
f.
Oxygen
11. What is this a molecule of? GLUCOSE
12. What is the balanced chemical equation for photosynthesis?
_____6 CO2_________ + ____6 H20___________  _____ C6H12O6____________ + ___6__ O2___________
6 carbon dioxide
+
6 water

1 Glucose
+
6 oxygen
13. What are all of the starting materials for photosynthesis and how do they enter the plant?
Carbon dioxide; enters through the leaves
Water; enters through the roots
14. What are the products of photosynthesis and how are they used by humans?
Glucose; we eat it for energy
Oxygen; we breathe it in so that we can break down glucose to get energy
15. What kind of energy is made in photosynthesis?
Glucose. Glucose is a molecule that contains stored energy.
16. Where in the plant cell does photosynthesis happen?
Photosynthesis happens in the chloroplast
17. What is the balanced chemical equation for respiration?

6 water
18. What are all of the starting materials for respiration and how do they enter a person?
Glucose; we eat it
Oxygen; we breathe it in
19. What are the products of respiration and how does a person get rid of them?
Carbon dioxide; we breathe it out
Water; we breathe it out
20. What part of a cell will cellular respiration happen in?
Respiration happens in the mitochondria
21. What kind of energy can a cell use?
A cell uses ATP
22. What is the purpose of respiration?
