then starch is not present...
Use iodine to test a leaf for starch | Plant Physiology | Biology
Starch, I think, because iodine solution is the test for starch.
starch
you turn orange
if you cover a boiled leaf in iodine you can see how much starch is in the leaf
The leaf was rinsed in water to rehydrate it. Iodine solution is an aqueous solution of iodine/potassium iodine - potassium tri-iodide; water is needed inside the leaf to enable penetration by diffusion.
to destarch a leaf, you have to have two things first. A leaf and a bottle of iodine solution. You need iodine solution to separate the sugar molecules (glucose molecules) to the leaf itself, on the upper epidermis of a leaf, on the cuticle.
the iodine stayed orange because the starch wasn't present
leaf
then starch is not present...
To get to the other side?!??
Iodine Solution is used to determine whether starch is present.
A iodine solution in water.
Iodine crystals
Nothing special happens and no reaction occurs. Iodine is hardly soluble in water.
