⩥ 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+
⩥ Products for light-dependent reactions.
Answer: O2 and the energy-storing compounds ATP and NADH
⩥ Requirements for light-independent reactions (Calvin Cycle).
