Plant Structure & Function * Flashcards
Where does photosynthesis take place
Inside chloroplasts
Is photosynthesis endothermic or exothermic
Endothermic meaning it requires energy
What is the source of energy for photosynthesis
Sunlight
How is sunlight trapped in the plant
by a chemical called chlorophyll inside chloroplasts.
What is the equation for photosynthesis
6CO2 + 6H2O → C6H12O6 + 6O2
What single called organisms perform photosynthesis
algae, cyanobacteria, and a few protists.
What multi cell organisms perform photosynthesis
Elysia chlorotica (a sea slug species) incorporates chloroplasts stolen from algae it eats into its own cells.
What wavelengths does chlorophyll take in
Red and blue
What wavelength do chlorophyll reflect
Green
What is the red limit
scientists believed there to be a ‘red limit’ that dictated the minimum amount of energy needed for photosynthesis.
How are water molecules held together
By storage intermolecular forces known as hydrogen bonds
What is the interaction between water molecules known as
Cohesion
What does transpiration move
Water and minerals
Water moves from the roots to the what?
Leaves
What is the rate of bubble movement equal to
Transpiration rate
