Total questions: 10
Worksheet time: 4mins
Which of the following statements is false?
Usually chloroplasts align themselves along the walls of mesophyll cells, so that they get optimum quantity of incident light
Within chloroplast there is a membranous system consisting of grana, stromal lamellae and stroma
There is division of labour within chloroplast
In grana CO2 is fixed
The membranous system of grana is responsible for –
Trapping light energy but not ATP and NADPH2 formation
Trapping light energy and also for fixation of CO2
For ATP and NADPH2 formation but not for light trapping
For light capturing and also for NADPH2 and ATP formation
In stroma –
Enzymatic reactions incorporate CO2 into the plant leading to ATP and NADH2 formation
Enzymatic reactions incorporate CO2 into plant leading to the synthesis of sugar, which in turn forms starch
Light energy is captured to form glucose
ATP and NADPH2 are splitted and H2O and O2 comes out
Leaf pigments, (Chl a, Chl b, Xanthophyll and carotene) can be separated by –
Paper chromatography
Electrophoresis
X-ray diffusion
ELISA test
Which one is not an accessory photosynthetic pigment?
Chl b
Xanthophyll
Carotene
Chl a
Why are the absorption spectrum of Chl a and the action spectrum of photosynthesis are identical?
Chl a absorbs both red and blue light maximumly
Chl a reflects blue light
Accessory pigments contribute energy to drive photosynthesis
Different wave lengths of light have different energy
If green plant cells are incubated with O18-labelled CO2, what molecule will become radioactive as the cells are exposed to light?
ATP
Water
Sugar
O2
Oxygen is not produced during photosynthesis by
Cycas
Nostoc
Green sulphur bacteria
Chara
Which of the following is not a product of light reaction of photosynthesis?
NADPH
NADH
ATP
Oxygen
One scientist cultured Cladophora in a suspension of Azotobacter and illuminated the culture by splitting light through a prism. He observed that bacteria accumulated mainly in the region of :
Blue and red light
Violet and green light
Indigo and green light
Orange and yellow light
