Lab: Photosynthesis & Chromatography
2026 With Questions And Answers Written
Correctly
Photosynthesis - correct answer<✔✔💖💖equation: 6CO₂ + 12H₂O + light -> C₆H₁₂O₆ + 6O₂ + 6H₂O
process that converts solar energy into chemical energy used to make sugar; occurs in plants
reactants are low in energy, product (sugar) is high in energy
biproducts: O₂ & H₂O
occurs in chloroplasts
Leaf Anatomy - correct answer<✔✔💖💖upper epidermis- protective covering, prevents water loss
& entering of pathogens; under layer of cuticle/cutin
palisade mesophyll- close to U epidermis, close together; contain chloroplasts
spongy mesophyll- under palisade mesophyll, large space btwn cells; allows gas movement thorugh leaf
vien- xylem (H₂O from stem to leaf) & phloem (sugars in all directions)
lower epidermis- protective covering, prevents water loss & entering of pathogens; under layer of
cuticle/cutin
stomata- openings that allow for gas exchange; controlled by guard cells (flaccid- closed, erect- open)
2 Stages of Photosynthesis - correct answer<✔✔💖💖light reaction- converts light energy to
chemical energy (ATP & NADPH(e- carrier)); occurs in thylakoids
calvin cycle- doesn't use light directly, gets chemical energy from light reaction & uses it to make sugars;
occurs in stroma
Photosynthetic Pigments - correct answer<✔✔💖💖molecules that trap solar energy from VLS
3 types: chlorophyll a, chlorophyll b, carotenoids
chlorophyll a- main photosynthetic pigment, absorbs most energy; green color b/c reflects green light;
abs peek 450 & 650
chlorophyll b- green pigment
