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 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.
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.
Most of the starch contained in a leaf is located within chloroplasts.
The major purpose of a potato cell is for storing starch. Potatoes are underground stems that store energy reserves in the form of starch, allowing the plant to survive and grow during periods when photosynthesis is not actively occurring.
Large carbohydrates such as glycogen, starch will not be transported in to the cell by cell membrane.

No, they contain too much oxygen so they can't enter our cells. They do however sectrete chemicals, and these chemicals enter 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.
The starch grains mainly contain starch which is produced from photosynthesis

the cytoplasm area
The starch did not enter the beaker because the membrane of the dialysis tubing is selectively permeable, allowing only smaller molecules, like glucose and water, to pass through. Starch molecules are too large to pass through the pores of the membrane, thus they were unable to enter the beaker.
