QUARTER 2 PIGMENTS Flashcards
A set of chemical compounds that have an intense colour and are used in the colouring of other materials
Pigments
Found in plants and animals.
Pigments
A process that capture light energy and convert it into sugars.
Begins with the absorption of light energy by a specialized form of organic molecules, pigments.
Photosynthesis
Types of Pigments in Plants
Chlorophylls
Carotenoids
Betalains
Flavonoids
plays a vital role in the biological process, photosynthesis.
Chlorophylls
Stimulates photosynthesis by reflecting green light and absorbed violet - blue and orange - red light.
Chlorophylls
Types of Chlorophylls
Chlorophyll a
Chlorophyll b
Chlorophyll c
Chlorophyll d
Chlorophyll e
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
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, 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
found in golden algae.
Chlorophyll e
Where can you find Carotenoids
In chloroplast and chromoplast of green plants
Where can you find Flavonoids
In the cell vacuole of
common plants
Where can you find Betalains
In the cell vacuole of Flowers and fungi
Where can you find pigments?
Plastids and Chloroplast
It is a double membrane organelle found in plants and algae.
Resposible in manufacturing and storing food
plastid
TYPES OF PLASTIDS
Chloroplasts
Chromoplasts
Gerontoplasts
Leucoplasts
Outer and Inner Membrane
Outer and inner covering of the chloroplast.
Space between the thylakoid and inner membrane
Site of the Calvin cycle phase of photosynthesis
Stroma
Skeleton of the chloroplast
Separate stacks of thylakoid
Stroma lamellae
Stacks of thylakoid
Granum
Contains the photosystem of the chloroplast
Made up of pigments and proteins that absorb light energy
Chlorophyll and carotenoids
Thylakoid
Site of the light dependent phase of photosynthesis
Thylakoid
