What does the presence of blue color means in variegated leaf experiment of photosynthesis?

By blue color I assume you mean an added dye that shows how some parts of the leaf can photosynthesize and others not.
The easiest of these experiments is to place the leaf in boiling ethanol (alcohol) and when drained of colour spread out on a flat surface. Soak the leaf in iodine and the green parts will turn blue/black and the non green parts will stay the yellowish brown colour of iodine. The green parts contain starch (a more compact form of glucose) which makes iodine turn blue/black. The blue/black is what will show starch is present.

Why is a variegated leafed plant useful for demonstrating that chlorophyll is needed for photosynthesis?
Variegated leafed plant is useful for demonstrating that chlorophyll is needed for photosynthesis because variegated leaf is a plant which uses chlorophyll to absorb light so it can get its color
What substances are in variegated leaves?
A leaf on a variegated plant is a leaf of different colors. Usually green and cream or pale brown.
What is meaning of variegated?
of Variegate, Having marks or patches of different colors; as, variegated leaves, or flowers.
Suggest an experiment to prove that theleaf is the organ of photosynthesis?
Iodine test. The leaves of plants absorb light & perform photosynyhesis. photosynthesis means In the presence of chlorophyll & light carbon dioxide & water combines to form carbohydrates(sugars). Leaf dipped into iodine solution after exposing to light will become blue in colour. It shows the presence of carbhydrates. That means leaf is the organ doing photosynthesis. generally iodine reacts with Carbohydrates and gives blue color.
What does chloroplast do in a cell?
It contains chlorophyll to trap sunlight for photosynthesis (in the presence of sunlight).

Where in a tree does photosynthesis occur?
Photosynthesis takes place in the leaves of a tree, which is evident by their green color. The green color is due to the presence of chlorophyll, which captures sunlight to convert C02 to oxygen.

How many colors do potatoes have?
Every color in the rainbow, plus black, white, and variegated.
Why iodine place in dark color bottles?
iodine is volatile in nature,in the presence of light iodine degraded & degradation of iodine disturb the experiment
What does chloroplast do in a cell?
It contains chlorophyll to trap sunlight for photosynthesis (in the presence of sunlight).
What color is a chromosome in a Plant Cell?
A chromosome in a plant cell is typically green in color. This is due to the presence of chlorophyll, which is a green pigment that helps the plant cell to absorb light for photosynthesis.
What color is an efficient color for photosynthesis?
Green.
Do variegated leaves contain starch?
sometimes the leaves which are not green contain chlorophyll. red /yellow like colored leaves contain it but the color pigment are higher than chlorophyll but the fact is colorless plants such as mushrooms doesn't contain it.
