Photosynthesis Flashcards
Process by which plants and other organisms with chlorophyll use the solar energy to produce sugar in form of GLUCOSE
Photosynthesis
Self-feeding
Autotrophs
Autotrophs came from the GREEK word AUTOS and TROPHE which means SELF NOURISHING
True
Main products of photosynthesis
Oxygen & Sugar
Not a raw material but a CATALYST
Sun
Transparent & covered w a waxy, waterproof cuticle
Upper epidermis
Filled with chloroplasts and carry on most of the photosynthesis in the leaf
Palisade Layer
Temporary storage of sugars and amino acids
Spongy layer
Regulate opening & closing of the Stomata
Guard Cell
Semi-porous membrane which is permeable to small molecules
Outer Membrane
Controls the exchange of materials in & out of the chloroplast
Inner membrane
Protein-rich watery alkaline fluid where thylakoid system, ribosome, DNA and other organelles lie
Stoma
Stack of 10-20 thylakoids
Granum
Links one thylakoid from one granum to another
Lamella
Small disk-like compartment
Contains he chlorophyll
Thylakoid
Occurs in the grana
Requires presence of light energy from the sun to produce energy molecules
Light-Dependent Reaction
Natural electron carrying molecule
Nicotinamide Adenine Dinucleotide Phosphate
Multi-protein complex
2 photosystems embedded in the thylakoid membrane
Adenosine Triphosphate (ATP) has
Released as product during photolysis
Oxygen Gas
Formed from hydrogen Ion from water and electron from chlorophyll
NADPH
Produced from ADP
ATP
Calvin Cycle
Occurs in the STROMA
Photosynthesis 2nd stage
Light-Independent Cycle
Where photosynthesis takes place
