CORRECT ANSWERS
◉ Equation for Photosynthesis in Words
Answer: water + carbon Dioxide + light energy --> glucose + oxygen
◉ Equation for Photosynthesis
Answer: 6H2O + 6CO2 + light energy --> C6H12O6 + 6O2
◉ Water enters plants through?
Answer: their roots
◉ Carbon Dioxide enters plants through?
Answer: pores in the leaf called stomata
◉ Photosynthesis occurs in?
Answer: chloroplast
,◉ Structure of a chloroplast
Answer: stroma, thylakoid membrane, grana, inner and outer
membrane
◉ Chlorophyll molecules are embedded in the?
Answer: inner thylakoid membrane
◉ The primary function of plant pigments is?
Answer: to absorb solar energy
◉ What happens in light dependent reactions?
Answer: Energy from sunlight is absorbed and converted into
chemical energy (ATP)
◉ Where do light dependent reactions take place?
Answer: thylakoid membranes of chloroplasts
◉ What is a light independent reaction called?
Answer: Calvin Cycle
◉ What happens in light independent reactions (Calvin Cycle)?
, Answer: Uses CO2 and the ATP and NADPH from light dependent
reactions to produce sugar/glucose.
◉ In the Calvin Cycle, ATP is used to?
Answer: provide the energy for sugar synthesis
◉ In the Calvin Cycle, NADPH is used for?
Answer: electrons in the reduction of carbon dioxide into sugar
◉ Where do light independent reactions (Calvin Cycle) occur?
Answer: the area in the chloroplast called the stroma
◉ Leaves are green because?
Answer: chlorophyll molecules absorb violet-blue and red light, but
reflect or transmit green-yellow light
◉ Process of light dependent reactions
Answer: chlorophyll absorbs solar energy and ejects an electron,
which is passed down an electron chain, and water is split, releasing
O2
◉ Requirements for light dependent reactions
Answer: H2O, ADP, and NADP+
