Do animal cells have a starch grain?
Cellulose is not an animal starch. It comes from the cell walls of plant cells.
Tiny sacs in the cell that may contain starch?
The tiny sacs in the cell that may contain starch are called amyloplasts. Amyloplasts are specialized organelles responsible for storing and synthesizing starch in plant cells. They play a crucial role in the storage of energy reserves in the form of starch.
How do potato cells differ from onion cells?
Potato cells have larger, more angular shape and contain starch granules, while onion cells are smaller and have a more rectangular shape with a distinct cell wall. Additionally, potato cells lack the characteristic onion cell layers seen in onion cells.
Why onion cells were stained with iodine but rhubarb cells were not?
Onion cells were stained with iodine because they contain starch, which reacts with iodine to produce a blue-black color, allowing for better visualization of the cells. In contrast, rhubarb cells do not contain significant amounts of starch, so staining with iodine would not yield a noticeable color change, making it unnecessary for observation. Thus, iodine staining is used selectively based on the presence of starch in the cells being examined.
Do variegated leaves contain starch?
Yes, variegated leaves contain starch. Starch is produced in the chloroplasts of plant cells during photosynthesis, so all green parts of a variegated leaf will have starch. However, the amount of starch present may vary depending on the extent of variegation and the amount of chlorophyll in the leaf.
What organic molecules do potato cells have?
Potato cells contain various organic molecules, including carbohydrates (such as starch and cellulose), proteins, lipids, vitamins, and organic acids. These molecules play important roles in the growth, metabolism, and function of potato cells.
What would happen to cells tested with iodine solution?
Cells that contain starch will turn blue-black when tested with iodine solution, indicating the presence of starch. Cells without starch will not change color in the presence of iodine solution. This test is commonly used to identify the presence of starch in cells.
Do animal cells have a starch grain?
Cellulose is not an animal starch. It comes from the cell walls of plant cells.
Is starch found in plant or animal cells?
Starch is primarily found in plant cells as a storage form of energy. It is produced through photosynthesis and stored in organelles called amyloplasts. Animal cells do not typically contain starch but store energy in the form of glycogen.
Why doesn't onion contain starch?
Onions do not contain starch because they store energy in the form of fructans instead. Fructans are a type of carbohydrate composed of fructose molecules, unlike starch which is composed of glucose molecules. This is why onions do not give a starch positive test such as the iodine test typically used to detect starch.
Do Elodea cells have starch?
if starch is present in a substance, the solution IKI when combined will turn the substance a blue-black color. When the plant Elodea was combined with IKI the elodea did not turn a blue-black color. Hence elodea does not contain starch.
Tiny sacs in the cell that may contain starch?
The tiny sacs in the cell that may contain starch are called amyloplasts. Amyloplasts are specialized organelles responsible for storing and synthesizing starch in plant cells. They play a crucial role in the storage of energy reserves in the form of starch.
Does fish have starch?
No, fish does not contain starch. Only plants contain starch.
Does pineapple juice contain starch?
No, it does not contain starch.
Does durian contain starch?
Yes it does contain starch.

Does cocoa contain starch?
no. It depends on the type of chocolate, but it many cases, yes it does contain starch.
