Multiple Choice QuestionsChlorophyll molecules are located in the
thylakoid membrane
thylakoid lumen
stroma
inner chloroplast membrane
A.
thylakoid membrane
The green pigment chlorophyll is located within the thylakoid membrane, and the space between the thylakoid and the chloroplast membranes is called the stroma.
Chlorophyll is specifically arranged in and around photosystems that are embedded in thylakoid membranes of chloroplasts. It also acts as a site of light dependent reactions of photosynthesis, while thylakoid lumen has vital role in photophosphorylation during photosynthesis, stroma is a colourless fluid has surrounding the grana within the chloroplast.
The correct sequence of organelles in which glycolate and glyoxylate are produced sequentially in photorespiration is
chloroplast and mitochondria
chloroplast and peroxisome
peroxisome and mitochondria
peroxisome and chloroplast
Identify the correct statements in relation to C4 photosynthesis.
Kranz anatomy is an essential feature for C4 plants
C4 plants have higher water use efficiency than C3 plants
Photorespiration can be minimised when C3 pathway is in operation
Conversion of oxaloacetate to malate occurs in the bundle sheath cells
C4 pathway is advantageous over C3 pathway in plants as it
occurs in relatively low CO2 concentration
uses more amount of water
occurs in relatively low O2 concentration
is less efficient in energy utilisation
Opening and closing of stomata is controlled by
abscisic acid
CO2 concentration
O2 concentration
light intensity
As compared to sun plants, the plants, which are adopted to low light intensity possess
more extended root system
very high rate of CO2 fixation
larger photosynthetic units
more extended shoot system
Oxygen released in photosynthesis comes outby
photophosphorylation
photolysis of water
photorespiration
Kelvin cycle
