Why use iodine in plant cells staining?
Iodine is used in plant cell staining to highlight the presence of starch. Iodine forms a complex with starch molecules, turning them blue or black, making them easily visible under a microscope. This staining method is commonly used to identify starch storage sites within plant cells.
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.
Why does lugol's iodine stain a cell?
iodine indicates polysaccharides, therefore plant cells can be stained with iodine, staining the chloroplasts- composed of starch(a polysaccharide), and the cell wall- composed of cellulose ( a polysaccharide)
What does lugol's iodine stain do to the activity of the cell?
I just did a lab in biology called "How Plant and Animal Cells Differ" and in the packet it had that question. The answer is: Lugol's iodine stain stops the activity of the cell. It kills whatever specimen it is staining.
Does plant or animal cell use photosynthesis?
Plant
What is in plant iodine?
Iodine is not naturally present in plants. Instead, iodine is typically found in seafood, dairy products, and iodized salt. If plants accumulate iodine, it is usually from the environment or from sources like iodine-containing fertilizers.
Why do we add iodine to the slide?
Iodine is added to the slide to enhance the contrast and visibility of certain cell structures, such as starch granules in plant cells. It reacts with specific components in the cell to produce a color change, making it easier to observe and study under a microscope.
Why are cells stained with iodine solution?
Cells are stained with iodine solution to visualize the presence of starch. Iodine reacts with starch to form a bluish-black complex, making it easier to visualize and distinguish starch-containing structures within the cell, such as amyloplasts or starch granules.
Why do you use iodine to stain a cell?
Iodine is used to stain cells because it binds to glycogen and starch, making them more visible under a microscope. This helps to visualize the cellular structures and identify specific components within the cell.
What does chloralplast do in a plant cell?
chloroplast are only in plant cells, they use photosynthesis to make ATP which is energy for the cell.
What does the VACUOLES in a plant cell?
A vacuole stores nutrients for later use in all cells including the plant cell
What does iodine do to the activity inside the cell?
It stops the activity within the cell.
