Starch itself cannot directly enter cells because it is a large polysaccharide. Instead, it is first broken down into smaller glucose molecules by enzymes like amylase during digestion. Once broken down, glucose is then absorbed into cells through transport proteins in the cell membrane, primarily via facilitated diffusion or active transport mechanisms such as the sodium-glucose co-transporter.
What else can I help you with?
Why is starch broken down outside the cell?
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.
How is energy made available to the cell to move large starch molecul across the process of endocystosis?
Energy for moving large starch molecules across the cell membrane via endocytosis is primarily derived from ATP. The process involves the cell membrane engulfing the starch molecules, forming a vesicle that internalizes them. ATP provides the necessary energy for the rearrangement of the cytoskeleton and membrane components, facilitating the vesicle's formation and transport within the cell. This energy-dependent mechanism ensures that large macromolecules can enter the cell efficiently.
What is the purpose of adding iodine solution to the onion cell?
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.
What is the colour for a plant cell's starch grains?
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.
For what major purpose was the potato cell specialized?
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.
Would help large carbohydrate molecule enter the cell?
Large carbohydrates such as glycogen, starch will not be transported in to the cell by cell membrane.
Why is starch broken down outside the cell?
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.
Do the carbohydrates you eat in the form of starch enter your cells?
No, they contain too much oxygen so they can't enter our cells. They do however sectrete chemicals, and these chemicals enter the cell
What does the starch grains do in the plant 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.
What is the functions of the starch in a plant cell?
The starch grains mainly contain starch which is produced from photosynthesis

Where would you expect to find cellulose in a palisade cell?
the cytoplasm area
Why did the starch not enter the beaker?
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.
Where do starch grains develope in a cell?
in the amyloplasts
Where is starch made in the plant cell?
cellulose
Where is starch located in a potato cell?
Vacuole
