Photosynthesis in Higher Plants Figure-Based Questionsย for NEET

Consider the given figure and answer the following questions

Photosynthesis in Higher Plants Figure-Based Questionsย for NEET

(a) What do X, Y and Z represent on the three curves in the above-given figure?

A.ย The given graph represents Blackman’s law of limiting factors. X, Y, Z represent different light intensities in foot candles.

(b) Sometimes deviations are observed in Blackmanโ€™s law and transitional curves are obtained. What could be the probable reason for this?

A.ย Transitional curves are produced when either of the two factors change the rate of the process. This occurs because the cells possess large and numerous chloroplasts in them, of which some receive more light while others get excess of CO2. Thus, rate of the process is affected.

(c) Mention the condition where light intensity and temperature act as limiting factors in photosynthesis.

A.ย Light intensity acts as a limiting factor in a shaded community of plant in, dawn and twilight in a warm climate, while temperature acts as a limiting factor on a bright winter day.
