What does the presence of starch in plants indicate?
The presence of starch in plants indicate that photosynthesis has occurred. The process of testing the presence of starch uses iodine solution that turns to blue-black on a positive test. ...

What is the role of mechanical digestion in breaking down starch in the mouth?
The breaking down of starch in the mouth is not mechanical digestion. It is chemical digestion that uses salivary amylase to break down the starch in the mouth. ...

This developing plant uses starch stored in the seed as a source of energy during germination This stored starch is a by-product of?
The stored starch is a by-product of photosynthesis. Photosynthesis produces glucose; plants can convert and store excess glucose as starch. Both sugar and starch are types of carbohydrates. ...

How will bean seeds give a positive test for starch?
The seed uses the starch until it become an adult plant or in other words, until it is fully grown to produce its own food. Inside the cotyledon, starch is present and thus, gives a positive result for starch :) ...
How does the mass of a plant increase as it grows?
As the plant photosythesises it creates glucose which it then turns into starch. As the plant uses the starch for growth it gets bigger and the mass increases ...
Asked in Science
Why are starch and cellulose considered different compounds even though they are built from the same monomer?
Starch and cellulose are both polymers built from glucose, but the glucose molecules are arranged differently in each case. Having different arrangements means that starch and cellulose are different compounds. They serve different functions in the plants that make them. Your body also uses starch very differently from the way it uses cellulose. ...
Asked in Chemistry, Biochemistry
Starch and cellulose are polysaccharides but you can eat or digest starch and not the cellulose why?
Both starch and cellulose are polymers of glucose. However, the individual glucose units are linked differently in the two. Humans have an enzyme which is capable of breaking the linkages used to form starch, but do not have one that can break the linkage used to form cellulose. (If you want the technical terms, cellulose uses a beta(1-4) link and starch uses both alpha(1-4) and alpha(1-6) links.) ...
Asked in Photosynthesis
Why should we place a plant in dark atleast for 24 hours before performing photosynthesis experiment?
I am guessing so that it uses the starch that it has so that when the starch test (experiment) is carried out later, you can be sure that the starch is being made currently. ...
Explain how the mass of a plant increases as it grows?
As the plant photosythesises it creates glucose which it then turns into starch. As the plant uses the starch for growth it gets bigger and the mass increases! source: my brain ...
Asked in Cornflour and Cornstarch
Who manufactures corn starch golf tees?
There are a number of manufacturers of corn starch golf tees around the world. There is a new development taking place with corn starch plastics and that is to combine the farming waste material like stalks and husks with corn starch to manufacture a biodegradable biomass type product. The product: 1. Uses waste (that would be burnt or discarded) 2. Is still biodegradable 3, Should be cheaper as it uses less processed material. ...
