Plants can create their own food. What is this process called? 1.Respiration 2.Photosynthesis 3.Conservation of Matter 4.All of the above Gas A H2OH2O O2O2 Stored Food

What is the stored “food” plants produce by the process of photosynthesis? Gas A H2OH2O O2O2 Stored Food 1.Starch 2.Cellulose 3.ATP 4.Glucose

Gas A and H 2 O are both __________ in this reaction? Gas A H2OH2O O2O2 Glucose 1.Reactants 2.Catalysts 3.Products 4.Both Reactants and Catalysts

O 2 and Glucose are both __________ in this reaction? Gas A H2OH2O O2O2 Glucose 1.Reactants 2.Catalysts 3.Products 4.Both Reactants and Catalysts

Sunlight is the __________ in this reaction? Gas A H2OH2O O2O2 Glucose 1.Reactants 2.Catalysts 3.Products 4.Both Reactants and Catalysts

Gas A is __________ in this photosynthesis reaction? Gas A H2OH2O O2O2 Glucose 1.O 2 2.CO 2 3.N 2 4.Can be any non toxic gas

How many carbon atoms does glucose contain? (6) CO 2 (6) H 2 O (6) O 2 Glucose C ? H 12 O

Which reactant supplies all of the carbon used to make glucose in photosynthesis? (6) CO 2 (6) H 2 O (6) O 2 Glucose C 6 H 12 O 6 1.carbon dioxide 2.water 3.oxygen 4.sunlight

Photosynthesis is known as the “light reaction” because it is catalyzed by light. What is known as the “dark reaction” because it doesn’t need light? 1.carbon-oxygen cycle 2.chlorophyll regeneration 3.glucose storage 4.respiration

Photosynthesis and respiration both take place in the chloroplast. 1.True 2.False

Photosynthesis uses sunlight to create glucose (stored energy) from CO 2 and H 2 O. Why does a plant also perform respiration? 1.to create additional glucose without sunlight 2.to create a usable form of energy from a stored form of energy 3.to use glucose to create ATP 4.both 2 and 3

(6) CO 2 (6) O 2 Plants use photosynthesis to create stored energy in the form of glucose. Respiration releases this stored energy and uses it to form ATP. Which is an exothermic reaction? (6) H 2 O (6) CO 2 (6) O 2 C 6 H 12 O 6 ATP (6) H 2 O ADP ENERGY 1.photosynthesis 2.respiration 3.the formation of ATP 4.both 2 and 3

(6) CO 2 (6) O 2 Why is photosynthesis an endothermic reaction? (6) H 2 O (6) CO 2 (6) O 2 C 6 H 12 O 6 ATP (6) H 2 O ADP ENERGY 1.it creates glucose 2.it absorbs more energy than it releases 3.it releases of O 2 4.all of the above

Animals do not use photosynthesis to create glucose. Where do they get their glucose from? C 6 H 12 O 6 ? 1.breaking down more complex sugars 2.eating plants 3.eating other animals 4.all of the above (6) CO 2 (6) O 2 (6) H 2 O ATP ENERGY ADP

(6) CO 2 (6) O 2 Does photosynthesis and respiration follow the Law of Conservation of Matter and Energy? Why or why not? (6) H 2 O (6) CO 2 (6) O 2 C 6 H 12 O 6 ATP (6) H 2 O ADP ENERGY 1.No, respiration is the only reaction to release energy 2.Yes, no matter or energy is lost in the reactions 3.Yes, no matter is lost and the sun’s energy is converted to another form 4.both 2 and 3
