BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS

336934 Which one of the following crop plants is very efficent converter of solar energy, with less water and high temperature?

1 Sorghum and maize

2 Rice and maize

3 Wheat and potato

4 Bajra and barley

Explanation:

$C_{4}$ plants are best in the conversion of solar energy in the presence of less water and high temperature. Examples are Maize and Sorghum.

336935 In $C_{4}$ pathway, the ${CO}_{2}$ fixation in mesophyll cells is carried out by the enzyme:

1 Rubisco

2 PEP carboxylase

3 Pyruvate decarboxylase

4 Pyruvate dehydrogenase

Explanation:

In $C_{4}$ plants, the carbon dioxide that enters the mesophyll cells is accepted by a 3 -carbon molecule called phospho enol pyruvate (PEP). The enzyme phosphoenol pyruvate carboxylase (PEPcase) catalyses the carboxylation of PEP.
$PEP + {CO}_{2} + H_{2} O \overset{PEP carboxylase}{\to} OAA + P_{i}$

336936 Photosynthetic rate is high in $C_{4}$ plants because

1 No photorespiration

2 Kranz anatomy

3 Photosynthesize in low light intensity

4 None of these

Explanation:

$C_{4}$ plants lack photorespiration, that is why productivity and yields are better in these plants. In addition these plants show tolerance to higher temperatures.

336937 Bundle sheath cells of $C_{4}$ plants show _

1 Thick walled cells and intercellular spaces

2 Thin walled cells and granal chloroplasts

3 Thick walled cells and no intercellular spaces

4 Thin walled cells and no intercellular spaces

Explanation:

Bundle sheath cells pf $C_{4}$ plants show thick walls impervious to gaseous exchange and no intercellular spaces.
