Chlorophyll

draw and name the structure of the chlorophyll

Grana , Lamellae , starch granules , Thylakoids

Explain how the presence of these structures increases efficiency of photosynthesis

It increases the surface area

why do see colours ? In plant, etc

there are different types of pigments in different plants. Light wavelengths that ARE NOT absorbed, they are reflected.

Chlorophyll a and b do no absorb green light / Carotenoids do to absorb red light

Accessory pigments surroundings the chlorophyll absorb different

what is a photosystem ?

the pigments are arranged in light harvesting clusters.

what wavelengths does both chlorophyll and carotenoids absorb ?

Both absorb wavelengths in the blue-violent region of the light spectrum.

what wavelengths does chlorophyll absorb but carotenoids doesn't?

Also absorb in the red region of the light spectrum.

what is in the photosystem ?

Primary pigment reaction and accessory pigments.

what is the primary pigments reactions ?

it contains chlorophyll a and b and carotenoids.

what is the accessory pigments ?

it enables absorption of more wavelengths of light, known as the 2nd pigments

what does both photosystem II and I does ?

It involves in absorbing light for the LDR of photosynthesis.
