The law of limiting factors for photosynthesis was enunciated by
R. Hill
Calvin
Krebs
Blackman
D.
Blackman
Blackman (1905) proposed the law of limiting factor according to which, "when a biological process is controlled as to its rapidity by a number of separate factors, the rate of the process is limited by the pace of the slowest factor.
Transpiration would be lowest when
wind velocity is high
enough water is in the soil
atmospheric RH is high
high temperature and light
Which of the following exhibits a direct porportionality to transpiration
Light and RH
Temperature and RH

The light phase of photosynthesis is called

photo action
pigment action
chlorophyllous process
The plant Cuscuta shows maximum photosynthesis in
red light
blue light
green light
no photosynthesis at all
