A tracheal cell is generally smaller than a starch grain. Starch grains, which are typically found in plant tissues as storage forms of energy, can vary in size but are often in the range of a few micrometers. In contrast, tracheal cells, which are part of the respiratory system in insects, are usually much smaller, often measuring less than a micrometer in diameter. Therefore, tracheal cells are smaller than starch grains.
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.
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.
Do animal cells have a starch grain?
Cellulose is not an animal starch. It comes from the cell walls of plant cells.
If both starch and glucose were added to the artificial cell where would the starch be located after 20 minutes?
In an artificial cell, starch would likely remain inside the cell due to its larger molecular size, which prevents it from easily passing through the cell membrane. Glucose, being a smaller molecule, would be able to diffuse through the membrane and could be found both inside and outside the cell after 20 minutes. Therefore, after 20 minutes, starch would primarily be located within the artificial cell, while glucose would be distributed in both compartments.
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 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.
How does a starch grain function in a chloroplast?

What cell parts are seen in plant cells?
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.
What contains starch in a plant cell?
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.

What is the functions of the starch in a plant cell?
The starch grains mainly contain starch which is produced from photosynthesis

Will starch diffuse if so in what direction?
Starch does not readily diffuse through cell membranes due to its large molecular size. However, in a solution, starch can diffuse in a gel-like medium, but this process is generally slow. If starch is placed in a solution with a lower concentration of starch, it may diffuse toward areas of lower concentration, but the movement is limited compared to smaller molecules. Overall, starch diffusion is minimal and highly dependent on the medium and conditions.
Which particles-starch or Lugol's-were able to cross the model cell membrane?
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.
