Based on the reaction with iodine What biological molecule is stored within these amyloplasts?
Amyloplasts primarily store starch, which is a polysaccharide made up of glucose units. When iodine is added to a sample containing starch, it forms a blue-black complex, indicating the presence of this carbohydrate. This reaction is commonly used to test for starch in biological samples.
What is molecular iodine?
Molecular iodine, represented as I₂, is a diatomic molecule consisting of two iodine atoms bonded together. It appears as a purplish-black solid at room temperature and sublimates into violet vapor when heated. Molecular iodine is commonly used as a disinfectant, antiseptic, and in various chemical reactions due to its strong oxidizing properties. Additionally, it plays a crucial role in thyroid hormone synthesis in biological systems.
What is iodine used to see when using a microscope?
Iodine is used as a stain to visualize cellular structures, such as nuclei and starch granules, in biological samples when using a microscope. It can help highlight these structures by binding to specific molecules and enhancing their contrast against the background.
What is lugol solution used for?
Lugol's solution is used as an iodine supplement to treat iodine deficiency conditions like goiter and to prepare patients for thyroid surgery. It is also used as an antiseptic for cleaning wounds and as a stain for biological samples in laboratories.
What type of substance is I2?
I2, or iodine, is a diatomic molecule composed of two iodine atoms. It is a nonmetal and exists as a solid at room temperature, typically forming dark purple or black crystals. Iodine sublimates easily, transitioning directly from solid to gas when heated. It is commonly used as a disinfectant and in various chemical applications.
What is idodine stain?
It is either iodine and it stains starch, or the other way around, starch that stains iodine, likely the former as it is biological. Starch or iodine can be used in chemical titrations also to indicate the presence of the other available in solution.

What chemical can be used to indicate the presence of starch?
The fat titties that I have that boys in my school stare at indicate the boners to the boys with smelly cocks.
What structure does iodine stain?
Iodine stains starch molecules blue-black. This is commonly used in biological staining techniques to visualize starch content in cells or tissues.
What does iodine solution indicate?
Iodine solution is commonly used as an indicator in starch tests. When iodine solution is added to a substance, such as food or a biological sample, it turns blue-black in the presence of starch. This color change indicates the presence of starch in the sample.

Is goitre a good indicater of iodine deficiency?
The goitre is used as a biological marker for iodine deficiency. Goitre manifestation indicates that other damaging effects of iodine deficiency are already present.
Why was iodine used to indicate starch?
Iodine (in fact the ion triiodide - I-3 - form with starch a very colored complex; the reaction is specific and sensible.
Are iodine crystals polar or non polar?
Ioddine chloride is a linear molecule with an electronegativity different of 0.5 meaning that the bond between I and Cl is polar. Since the molecule is linear, the molecule is over-all is polar.
Which biological molecule is called the backbone of biological molecules and is not used in diagrams?
The carbohydrate molecule is often referred to as the backbone of biological molecules as it is essential for storing and providing energy. However, carbohydrates are often not represented in diagrams of biological molecules for simplification purposes.

What is Iodine solution?
It tests for starch
