Starch is too big to enter cells, so it is broken down into smaller molecules like glucose outside the cell. These smaller molecules can then be transported into the cell for energy production.
The colour for a plant cell's starch grains is typically blue or black when stained with iodine solution. This is due to the formation of a complex between iodine and starch, which results in the characteristic colour change.
Cellulose is not an animal starch. It comes from the cell walls of plant cells.
The purpose of adding iodine solution to the onion cell is to stain the cell's starch granules. Starch granules will appear blue-black when iodine solution is added, allowing for easy visualization of the presence of starch in the cell.

starch grains store food for plant cell .the starch grain just re-produces on and on. but like the Amyloplast, amyloplast gives away starch grain in its cell.

In a plant cell there are: Cell Wall, Cell Membrane, Starch Grain, Cytoplasm, Nucleus, A Vacuole and Chloroplast. They are the main cell parts found in a plant cell. Hope this helps.
Starch is stored in plant cells in organelles called amyloplasts. Amyloplasts are specialized plastids that specifically accumulate and store starch granules. They are commonly found in storage organs such as roots, tubers, and seeds.

The starch grains mainly contain starch which is produced from photosynthesis

The Lugol's solution particles were able to cross the model cell membrane, while the starch particles were too large to pass through. Starch is a large molecule that cannot diffuse across the membrane, while Lugol's solution contains smaller molecules (iodine and iodide ions) that are able to pass through.
