Answer:

Hey!

Your answer is The presence of starch in leaves is testing with the Iodine test!

Explanation:

The presence of starch in the leaf would be represented by the blue / black tint of the Iodine when put on the sample...

Iodine solution is used to test leaves for the presence of starch...heat a plant leaf in boiling water for 30 seconds...

Check that it is soft before removing it out of the beaker...

Spread on a WHITE tile...

And now place a few drops of Iodine onto the leaf...

*if it turns dark (blue/black), STARCH IS PRESENT*

*no real change in colour means there is not starch present!*

HOPE THIS HELPS!!

Answer:

The presence of starch in leaves is testing with the Iodine test.

Explanation:

First, chlorophyll is removed from the leaf by boiling it in alcohol.

Then, two drops of iodine solution are put onto the leaf.

If the colour changes to blue, it indicates the presence of starch.

If it does not, there is no starch.

I hope this helps!
