Photosynthesis apparatus and general - Basic

Dear Readers,

The photosynthetic apparatus is a complex machinery consisting of several large protein–pigment complexes whose components are encoded by both nuclear and chloroplast genes. Thus, the biosynthesis of this system involves two distinct genetic systems which act in a coordinate manner.

Q1.  Chlorophyll molecules has the structure like

•   Monopyruvic
•   Dipyruvic
•   Tripyruvic
•  Tetrapyruvic

Tetrapyruvic

Q2.  Chlorophyll ‘e’ is generally present in

•  Thallophytes
•  Rhodophytes
•  Mycophytes
•  Xanthophytes

Xanthophytes

Q3.  A pigment which absorbs red and far-red light is

•  Phytochrome
•  Carotene
•  Cytochrome
•  Xanthophyll

Phytochrome

Q4.  The value of Q₁₀ for photosynthesis is

•  4
•  6
•  7
•  2 to 3

2 to 3

Q5.  Which of the following is correct for photosynthesis

•  Biological oxidation process
•  Photochemical catabolic process
•  Photo-oxidative metabolism
•  Biological photometabolism

Biological photometabolismn

Q6.  Which of the following is the non-polar part of chlorophyll

•   Phytol
•  Porphyrin
•  Pyrrol
•  None of the above

Phytol

Q7.  In prokaryotes, the photosynthetic lamellae remain in

•  Group
•  Isolated
•  Associated with nucleus
•  None of the above

Isolated

Q8.  In normal chloroplast, the percentage of chlorophyll is

•  75%
•  5–10%
•  95%

5–10%

Q9.  Photosynthetic pigments in chloroplast are embedded in membrane of

•  Thylakoids
•  Photoglobin
•   Matrix
•  Envelope of chloroplast

Thylakoids

Q10.  Which fractions of the visible spectrum of solar radiations are primarily absorbed by carotenoids of the higher plants

•  Violet and blue
•  Blue and green
•  Green and red
•  Red and violet

Violet and blue
