Question
The C-4 plants are photosynthetically more efficient than C-3 plants because
-
the CO2 compensation point is more
-
CO2 generated during photorespiration is trapped and recycled through PEP carboxylase
-
the CO2 efflux is not prevented
-
they have more chloroplasts
Solution
D.
they have more chloroplasts
Chloroplasts in bundle sheath cells are larger and always contain grana whereas chloroplasts in mesophyll cells are smaller. The C4 - plants are photosynthetically more efficient than c3 -plants because they more chloroplasts.
