What else can I help you with?
What observations do you need to expect if starch is present when testing leaf for starch?
It can be observed that when testing for starch their must be a olour change of blue black after iodine solution was added.Before the colour change was green that changed to blue black of the whole procedure is been carried out.
What does the presence of blue color means in variegated leaf experiment of photosynthesis?
By blue color I assume you mean an added dye that shows how some parts of the leaf can photosynthesize and others not. The easiest of these experiments is to place the leaf in boiling ethanol (alcohol) and when drained of colour spread out on a flat surface. Soak the leaf in iodine and the green parts will turn blue/black and the non green parts will stay the yellowish brown colour of iodine. The green parts contain starch (a more compact form of glucose) which makes iodine turn blue/black. The blue/black is what will show starch is present.
How much starch is in greenbeans?
Green beans contain about 5-7% starch by weight, depending on the variety and maturity of the beans. Starch content is typically higher in fresh green beans compared to canned or frozen varieties.
Are green bananas a starch?
Certain enzymes in bananas convert starch in the banana into sugar, which is part of the ripening process and what makes the fruit sweeter and softer as it ripens. Therefore, the greener the fruit is the more starch it will contain.
A green leaf is bleached before conducting the starch test because?
bleaching removes the chlorophyll pigments from the leaf, making it easier to observe the starch produced during the starch test. Chlorophyll can interfere with the detection of starch as it also gives a green color to the leaf. By bleaching the leaf, we can ensure that any starch present is more visually distinguishable.
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
Which plants store starch?
All green plants store starch
What kinds of organisms makes starch?
Organisms such as green plants produce starch.
What happens to starch in banana when it gose from green to ripe?
The starch is converted into glucose.
What observations do you need to expect if starch is present when testing leaf for starch?
It can be observed that when testing for starch their must be a olour change of blue black after iodine solution was added.Before the colour change was green that changed to blue black of the whole procedure is been carried out.
What happened a non green leaf is tested for starch?
A non-green leaf lacking chloroplasts will not be able to synthesize food which later on gets converted into starch. So it will not show the presence of starch in the test.

Would starch be found in leaves that are neither green nor white?
yes there would be starch in it
Do non green leaves have starch present in them?
Yes, non-green leaves that are exposed to light can still contain starch. Starch is produced through photosynthesis, so any leaf that is actively producing energy through photosynthesis can accumulate starch, regardless of its color.
Do green beans have starch in it?
yes black beans have carbohydrates in them!
What color is glucose when lugol's iodine is added?
I did this lab experiment in my biology class. When Lugol's indicator is added to glucose, it turns to a dark green colour for starch it turns black and for surcose it turns yellow.
How much starch is in greenbeans?
Green beans contain about 5-7% starch by weight, depending on the variety and maturity of the beans. Starch content is typically higher in fresh green beans compared to canned or frozen varieties.
