Starch is the main carbohydrate found in plant tubers and seed endosperm in the form of granules. Starch contains mylose and amylopectin molecules. It is found in various carbohydrates such as white bread, potatoes, beans and rice.

When does starch accumulate in leaves and how do you test for it?
Starch accumulates in leaves when it goes through photosynthesis, and they store extra food in the form of starch.
What happens to the sugar produced in the leaves of a plant?
it is changed to starch before it can be stored in the leaves,stems,or roots.
What is the process that produces starch from the leaves?
because it is a big molecule
What do leaves produce that is stored in starch?
In the leaf excess glucose is rapidly converted to starch. During photosynthesis, plants produce glucose and oxygen, reacting with water and carbon dioxide CO2. But during this process , plants often change some of the glucose into starch, for storage.
What substance is made in the leaves and used as food for the plant?
Starch or glucose
When does starch accumulate in leaves and how do you test for it?
Starch accumulates in leaves when it goes through photosynthesis, and they store extra food in the form of starch.
How do you exract starch from leaves?
You cannot.ANS#2:By the process of Retro-gradation starch can be extracted from leaves.
Is starch stored in leaves of some plants?
after the plant photosynthesises, it has some left over glucose that the leaves covert into starch. The starch is then stored in the chlorophyl (the green pigment in the leaves). At night or in the dark, the plant can't photosynthesise so it respires the stored starch instead
Is there starch in purple leaves?
yes
What types of substances are stored by plants?
starch is one substance stored in plants because starch is not osmotically active
Would starch be found in leaves that are neither green nor white?
yes there would be starch in it
How does plant store food in their leaves?
They store glucose as starch in their leaves. starch is a branched polymer of glucose. it it used as it is stable and does not upset the water potential of the cell.
What happens to the sugar produced in the leaves of a plant?
it is changed to starch before it can be stored in the leaves,stems,or roots.
What would be the conclusion after testing a leaf for starch?
Starch is produced by leaves during Photosynthesis, therefore if the leaf has not been exposed to light then it will not contain starch, and so when tested the Iodine will stay Yellow/Brown. Consequently if the leaf has been left in the light Photosynthesis will have taken place and when tested the Iodine will go Blue/Black showing that Starch is present. Hope this helps :)
What is the process that produces starch from the leaves?
because it is a big molecule
Why do green leaves turn blue black when iodine is added?
because the leaves have photosynthesized- glucose is produced. therefore, the excess glucose is converted to starch. The starch is then stored in the leaf-starch is what causes the "green" leaf to turn blue black, as iodine turns blue-black when it reacts with starch.:P
Result of starch test on variegated leaves?
the leaf that contains starch will turn blue/black if not it will stay the same colour
