Chlorophyll is necessary for photosynthesis class 10

Hint: Chlorophyll is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants.

Chlorophyll is concentrated within organisms in structures called chloroplasts grouped inside plant cells. Two types of chlorophyll exist in the photosystems of green plants: chlorophyll \[a\] and \[b\].

Complete answer:
1.Take a potted plant with variegated leaves and keep it in a dark region, away from sunlight for about \[3\] days.

How can you check that chlorophyll is necessary for photosynthesis class 4

This will halt photosynthesis and destarch the plant.
2.Then keep the plant facing the sunlight for \[6 - 8\] hours. The plant can again carry out photosynthesis and produce starch.
3.Mark the green areas in the leaf and trace them on a sheet of paper.

Mark the regions as green and yellow. The green areas contain chlorophyll which is absent in the yellow areas.
4.Immerse the leaf in boiling alcohol to decolourize it. Leaf slowly loses its green colour, which goes into the alcohol.
4.Dip this decolorized leaf in iodine soluti
