Practice Questions and Answers
What is the structure and function of the different parts of the leaf
(mesophyll and stomata)? - Answer✔️✔️-Mesophyll is the green material of
a leaf that allows the plant to enact the process of photosynthesis.
stomata is the openings or pores in the leafs that allow for gas exchange
Know the chemical equation for photosynthesis. - Answer✔️✔️-6CO2 +
6H2O + sunlight energy = C6H12O6 + 6O2
What are the different parts of the chloroplast and where do the different
steps of photosynthesis take place? - Answer✔️✔️-Thylakoid: one of the
green discs.
Granum: stack of thylakoids
lumen: the shit inside the thylakoid
stroma: the aqueous fluid
Photosynthesis takes place inside plant cells in small things called
chloroplasts.
What is the reactants that go into the light reaction and what products are
created? - Answer✔️✔️-Reactants: Light, H20
Biology 1320 :Texas State University
products: ATP, NADPH
What are the reactants for the light independent reaction, where do they
come from, and what are the products of the Calvin cycle? - Answer✔️✔️-
occurs in stroma.
reactants: NADPH, ATP, and C02
products: glucose
Know that ATP and NADPH are energy carrier molecules. - Answer✔️✔️-
What is the role of chlorophyll a and the accessory pigments in the light
reaction? - Answer✔️✔️-chlorophyll a is the primary photosynthetic
pigment in plants. it absorbs mostly blue and red light.
How do we measure the intensity of light? Which is stronger, red light or
blue light and why? - Answer✔️✔️-in wavelengths. blue light because it has
shorter wavelengths.
Understand the role of chlorophyll in photosynthesis? What light does
chlorophyll absorb or reflect? - Answer✔️✔️-chlorophyll a absorbs blue
light, chlorophyll b absorbs red light, both reflect green light which causes
chlorophyll to be green
Know the chemical equation for complete glucose breakdown (glycolysis
and cellular respiration) and how this relates to photosynthesis. -
Answer✔️✔️-602 + C6H12O6 -> 6C02 + 6H20 + energy (ATP)
