Question

Why is the colour of a leaf kept in the dark frequently yellow, or pale green? Which pigment do you think is more stable?

Answer 1

hey mate......



answer is.. Since leaves require light to perform photosynthesis, the colour of a leaf kept in the dark changes from a darker to a lighter shade of green. Sometimes, it also turns yellow. The production of the chlorophyll pigmentessential for photosynthesis is directly proportional to the amount of lightavailable..



Hope it's hlp uh

Answer 2

The colour of a leaf kept in the dark frequently get Yellow or pale green colour due to the loss of chlorophyll.

1. Chlorophyll is essential pigment for the performance of photosynthesis and is produced only in case of availability of Sunlight.

2. The leaf is kept in dark there will be no availability of Sunlight and leaves cannot synthesise chlorophyll as the amount of Sunlight available is directly proportional to the production of chlorophyll.

3. And chlorophyll is the pigment which adds green colour to the leaf.
