Ex 11 Q5 $Suppose there were plants that had a high concentration of Chlorophyll b, but lacked chlorophyll a, would it carry out photosynthesis? Then why do plants have chlorophyll b and other accessory pigments?$
Ex 11 Q6 $Why is the colour of a leaf kept in the dark frequently yellow, or pale green? Which pigment do you think is more stable?$
Ex 11 Q7 $Look at leaves of the same plant on the shady side and compare it with the leaves on the sunny side. Or, compare the potted plants kept in the sunlight with those in the shade. Which of them has leaves that are darker green ? Why?$
Figure 11.10 shows the effect of light on the rate of photosynthesis. Based on the graph, answer the following questions:
