Identify the family of the green house crops which show greater productivity in higher \(C{O_2}\) concentration _
1 Liliaceae
2 Fabaceae
3 Brassicaceae
4 Solanaceae

Statement A : Carbon dioxide is the major limiting factor for photosynthesis Statement B : \({C_4}\) plants show saturation at about 450 ulL-1 while \({C_3}\) plants show saturation beyond 360 ulL-1
1 Statement-A is correct but Statement-B is incorrect
2 Statement-A is incorrect but Statement-B is correct
3 Both the statements are correct
4 Both the statements are incorrect
Explanation:
Carbon dioxide is the major limiting factor for photosynthesis. \({C_4}\) plants show saturation at about 360 µlL-1 while \({C_3}\) responds to increased \(C{O_2}\) concentration and saturation is seen only beyond 450 µlL-1.
