photosynthesis

1.

What are the reactants of cellular respiration in plants?

• carbon dioxide and water

• glucose and carbon dioxide

• the reactants of the electron transport chain

• oxygen and glucose

.

In the first stage of photosynthesis,

• carbon compounds are produced

• the Calvin cycle takes place

• sunlight is required to generate ATP

• carbon dioxide is utilized

which of the following is a reactant to photosynthesis?

• Oxygen

• Carbohydrates

• Glucose

• Water

Why are plants considered autotrophs

• They make their own food

• They provide food for others

The process of converting carbon dioxide into sugars is called what?

• Photosynthesis

• Glycolisis

• The Calvin Cycle

• Cellular Respiration

What are the products of photosynthesis?

• Glucose

• sunlight

• water

What two forms of energy are produced from the light-dependent reaction?

• Energy and water

• ATP and ADP

• ATP and NADPH

• NADP and NADPH

Why do some leaves turn from green to red, orange, or yellow in the fall?

• Chlorophyll breaks down and its stored

• Chlorophyll production increases

• Chlorophyll leaks out of the leaves

• Chlorophyll changes colors in cool weather

Why does chlorophyll make plants appear green?

• Reflecting all colors expect green

• Absorbing all colors and reflecting back green

• Not absorbing any colors

• Leaves aren't green, what do you mean?!

What occurs in the Calvin Cycle of photosynthesis?

• nothing happens there is no energy

• glucose is synthesized from CO2

• Oxygen is being converted into sugar
