1406 Lab Practical ( Final)(photosynthesis)

Know the formula for photosynthesis.

12H2O+6CO2 -> 6O2+C6H12O6 + 6H2O

What is the visible light spectrum and the colors that represent the different wavelengths?.

____ light has the most energy whereas ____ light has the least of visible light.

violet/blue,red

What is and how does a spectroscope work?

used to separate the wavelengths of white light.

What is the absorption spectrum for chloroplast extract?

violet, blue, red

What is the transmission spectrum for chloroplast extract?

green, yellow

How does the above compare with the absorption spectrum of the green, red or blue filter?

Be able to interpret results on a chromatogram.

pigments separate by molecular weight, lightest at the top. from the top down, caratanoids to chlorophyll a

What plant was used to make the chlorophyll extract?

Look at a treated leaf and determine if it is from a geranium plant grown in the dark or light.

Know the parts of the chloroplast.

ribosomes,starch grain, granum, stroma, lamella, thylakoid disk, inner membrane, outer membrane.

Be familiar with the light dependent and light independent reactions, the products,reactants and the location in the chloroplast where these reactions take place.

light dependant reactions take place in the thylakoid membrane which is called the lumen. the light independent reactions take place in the stroma( calvin cycle) the light dependant reactions have photosytem II AND photosystem I (photosystem I only makes ATP) ( photosystem II produces ATP, NADPH and O2)

light dependent

light independent
