Soil erosion is greater when

Fill in the blanks.
(i) 4-C compounds like A or B formed in mesophyll cell of C₄ plants are transported to the bundle sheath.
(ii) The bundle sheath cells are rich in an enzyme C but lacks D.
(iii) E pathway is common to C₃ and C₄ plants.
(iv) The active site of RuBisCO has both F and G_binding sites. It has greater affinity for H.
(v) PGA binds with O₂ to form one molecule of I and J in a pathway called photorespiration.
(vi) C₄ acid from the mesophyll is broken down in the bundle sheath cells to release K- this results in increasing the concentration of L.
(vii) M is the major limiting factor for photosynthesis.
(viii) Increase in concentration upto N % can cause an increase in CO₂ fixation rates; beyond this the level can become damaging over longer periods
(ix) C₄ plants show saturation at about O u1L^-1 while C₃ responds to increased CO₂ concentration and saturation is seen only beyond P u1L^-1.

Which plant will lose its economic value, if its fruits are produced by induced parthenocarpy?
