This feature is an adaptive, as the redistribution of
chloroplasts within the cells modulates light absorption and prevents
photodamage, diagram shows of chloroplast distribution patterns in Arabidopsis
palisade cells in response to different light intensities;
m) A-low light, B-high light, C-darkness
n) A-high light, B-darkness, C-low light
Based on the above light intensities, each shows
different chloroplasts position such as,
i) chloroplasts avoid sunlight by migrating to the
side walls of palisade cells
ii) chloroplasts move to the bottom of the cell,
although the physiological function of this position is unclear
iii) chloroplasts optimize light absorption by
accumulating at the upper and lower sides of palisade cells
Which of the following correct combinations shows light intensities and chloroplast movements?
