11.1 — introduction to photosynthesis Flashcards
what are the products of photosynthesis?
glucose and oxygen
what are the products of respiration?
carbon dioxide and water (and energy)
what does photosynthesis do?
photosynthesis captures light energy to make glucose from carbon dioxide and water
what is the overall equation for photosynthesis?
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
what is the overall equation for respiration?
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
why are leaves adapted to have a large surface area?
to absorb sunlight
why are leaves adapted to have minimal overlapping?
to avoid shadowing
why are leaves adapted to be thin?
to keep diffusion pathway/distance short
why are leaves adapted to have a transparent cuticle and epidermis?
to allow light to enter the leaves
why are leaves adapted to have chloroplast-packed mesophyll cells?
to carry out photosynthesis
why are leaves adapted to have a stomata?
for gas exchange, like taking in carbon dioxide for photosynthesis
why are leaves adapted to have xylem and phloem?
to transport reactants and products of photosynthesis between the leaves and the rest of the plant
