Photosynthesis Flashcards
study of energy flow within living systems
Bioenergetics
gets energy from photosynthesis
Producers (autotrophs)
gets energy from cellular respiration
Consumers (heterotrophs)
gets energy from recycling nutrients from wastes and remains of dead organisms
Decomposers
high-energy molecules that stores the energy needed to do work
Adenosine Triphosphate (ATP)
converting solar energy into chemical energy stored in sugar molecules (glucose)
Photosynthesis
carry out photosynthesis
Chloroplasts
most-used pigments
chlorophyll a, chlorophyll b, carotenoids
photosynthesis occurs in _______, middle layer of leaves
mesophyll
tiny opening in the leaves where gases pass through
stomata
make up the mesophyll tissues and contain the chloroplasts
Parenchyma cells
tiny disk-shaped structures and are contained in the chloroplasts
Thylakoid
stack of thylakoids
Granum
enzymatic space that surrounds the granum
Stroma
green pigment molecule, is embedded inside the thylakoid membrane
Chlorophyll
space inside the thylakoid membrane
Lumen
occurs in the thylakoid membrane of chloroplasts and when light is available
Light - dependent
occurs in the stroma of the chloroplasts
Light - independent
group of pigments and proteins located in the thylakoid membrane. serve as charging systems for electrons.
photosystems
packet of light
photons
