Chloroplast: A cytoplasmic
organelle characterised by the presence of a green
pigment called chlorophyll .
Cytochromes: These are
iron-containing compounds which are exclusively electron transporters.
Quantasomes: Distinct structural
units in thylokoid which form a photosynthetic
Photosystem: Pigment system for
trapping light energy.
Photolysis of Water: Splitting of water molecule into
hydrogen and oxygen under the influence of light.
Photophosphorylation: The formation of
energy-rich ATP molecules during the process of photosynthesis.
Calvin Cycle: The cyclic reactions through which RuBP is generated to accept the carbon dioxide in order
to form fresh phosphoglyceric acid (PGA).
CAM Plants: Plants showing crassulacean acid metabolism for fixing CO2
C3 Plants: Plants in which the first product of
photosynthesis is a 3 carbon compound, i.e. PGA.
C4 Plants: Plants in which the first product of
photosynthesis is a 4 carbon compound, i.e. OAA.
Cyclic Photophosphorylation: A type of photophosphorylation in which the released electrons from
the chlorophyll molecules ultimately return to chlorophyll in a cyclic path.
Non-cyclic Photophosphorylation: A type of photophosphorylation in which the electrons released by
the chlorophyll molecules do not return to the chlorophyll.
