Ch.10: Photosynthesis Flashcards
is the process that converts solar energy into chemical energy
Directly or indirectly, XXXXX nourishes almost the entire living world
photosynthesis
The energy that maintains almost all life on Earth comes from
the sun
Reactants and Products of Photosynthesis
Reactants: Carbon dioxide &water
Products: Sugar, Water, & Oxygen
Characteristics of Autotrophs
sustain themselves without eating anything derived from other organisms
PRODUCERS: producing organic molecules from CO2 &other inorganic molecule
Almost all plants are ____________, using the energy of sunlight to make organic molecules from H2O and CO2
photoautotrophs
the entire range of electromagnetic energy, or radiation
electromagnetic spectrum
consists of wavelengths (including those that drive photosynthesis) that produce colors we can see
visible light
What color light does not get absorbed by photosynthesis
green
Wavelength and Energy correlation
longer wavelength = low energy
shorter wavelength = high energy
is the main photosynthetic pigment
chlorophyll
Accessory pigments, such as __________, broaden the spectrum used for photosynthesis
chlorophyll b
Accessory pigments called _________ absorb excessive light that would damage chlorophyll
carotenoids
Where does photosynthesis take place?
chloroplast
are the major locations of photosynthesis, contain the majority of chloroplast
leaves
Chloroplasts are found mainly in cells of the ________, the interior tissue of the leaf
mesophyll
