chlorophyll and pigments Flashcards
A set of chemical compounds that have an intense colour and are used in the colouring of other materials.
Biological Pigments or Biochromes
it is insoluble in water and
appear as ground particles in solid form.
Biological Pigments or Biochromes
Found in plants and animals.
Biological Pigments or Biochromes
Where can you find this pigments?
Inside a plastid
It is a double membrane organelle found in plants and algae. Responsible in manufacturing and storing food
plastid
Chloroplasts
chlorophyll
Chromoplasts
ageing chloroplasts, other pigments
Gerontoplasts
aged chromoplasts
Leucoplasts
found in roots and stems. Storage of starch, proteins, and lipids.
A process that capture light energy and convert it into sugars.
Photosynthesis
Begins with the absorption of light energy by a specialized form of organic molecules, pigments.
Photosynthesis
plays a vital role in the biological process, photosynthesis.
Chlorophylls
Primary photosynthetic pigments.
Chlorophylls a and b
Contains methyl group in the third position of its chlorin ring
Chlorophyll a
Principal pigment that captures sunlight for photosynthesis
Chlorophyll a
Absorbs violet- blue and orange- red light from the spectrum
Chlorophyll a
Reflects blue green in color
Chlorophyll a
Found in all plants, algae, and cyanobacteria
Chlorophyll a
Contains an aldehyde group in the third position of its chlorin ring
Chlorophyll b
Accessory pigments that collects sunlight and passes it into Chlorophyll a
Chlorophyll b
Absorbs orange- red light from the spectrum
Chlorophyll b
Reflects yellow green in color
Chlorophyll b
Found in all plants and green algae
Chlorophyll b
found in certain photosynthetic Chromista and in some marine algae.
Chlorophyll c
found only in red algae.
Chlorophyll d
Very rare and found in golden algae.
Chlorophyll e
Common types are Carotenes and xanthophylls (e.g. lycopene)
Carotenoids
it is found in chloroplast and chromoplast of green plants (masked by chlorophyll), vegetables like carrots, mangoes, etc.
Carotenoids
Examples of typical colors are; Oranges, reds, yellows, pinks
Carotenoids
capture light energy and transfer it to the chlorophyll a
Carotenoids
Common types are Anthocyanins, aurones, chalcones, flavonols and proanthocyanidins
Flavonoids
It is found in the cell vacuole of
common plants such as berries, eggplant, and citrus fruits. Present in certain teas, wine, and chocolate.
Flavonoids
Example colors are; Yellow, red, blue, purple
Flavonoids
play a role in the colors of ripening fruit
Flavonoids
common types are Betacyanins and betaxanthins
Betalains
found in the cell vacuole of Flowers and fungi
Betalains
Example colors are; Red to violet, also yellow to orange
Betalains
play an important role in attracting animals to flowers and fruit and is also food colorants
Betalains
600 naturally occurring….?
carotenoid
7,000 _______, including over 500 ________.
Flavanoids, anthocyanin
covering of the chloroplast.
Outer and Inner Membrane
Space between the thylakoid and inner membrane
Stroma
Site of the Calvin cycle phase of photosynthesis
Stroma
Skeleton of the chloroplast
Stroma lamellae
Separate stacks of thylakoid
Stroma lamellae
Stacks of thylakoid
Granum
Contains the photosystem of the chloroplast
Thylakoid
Made up of pigments and proteins that absorb light energy
Thylakoid
Chlorophyll and carotenoids
Thylakoid
Site of the light dependent phase of photosynthesis
Thylakoid
