Where is the most starch found in the plant cell?
Most of the starch contained in a leaf is located within chloroplasts.
Why did the leaf turn brittle in testing a leaf for starch?
The leaf turns brittle during the testing the leaf for starch because the ethanol extracts the all water content from the leaf.
What is contained within nutrient molecules?
starch and sugars
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 is needed for starch production in a leaf?
sunlight, water and CO2.
Where the most starch found in a plant cell?
Most of the starch contained in a leaf is located within chloroplasts.
Where is the most starch found in the plant cell?
Most of the starch contained in a leaf is located within chloroplasts.
Where is starch stored in a variegated Coleus leaf?
The starch in a variegated Coleus leaf is stored in the pigmented parts of the leaf. Coleus is a flowering plant is usually considered an ornamental plant because of its color.
Which part of the plant cell has starch?
Iodine binds to starch and would be primarily used to stain plant cells. The organelles that would be stained darkest would be the nucleus, amyloplast, which store starches, and chloroplasts which produce it.
How is starch produced in the leaf?
When the plant is kept in sunlight the starch is formed in leaf.
How do you determine the location of starch in a leaf?
To determine the location of starch in a leaf, one can examine it under the microscope and apply one small drop of iodine to the leaf. The parts of the leaf that turn purple contain starch.
Why did the leaf turn brittle in testing a leaf for starch?
The leaf turns brittle during the testing the leaf for starch because the ethanol extracts the all water content from the leaf.
How can you remove the starch from a leaf?
Starch is a complex carbohydrate. The presence of starch in leaves or plants can be detected by iodine test. In microscopic studies, starch granules can be seen under magnification inside the cells.
Where would you expect to find cellulose in a palisade cell?
the cytoplasm area
Does the leaf contain starch?
no
What did you see on the leaf in the test tube when testing for starch?
Use iodine to test a leaf for starch | Plant Physiology | Biology
What is the role of iodine in testing a leaf for starch?
A hot bath of ethanol decolorizes the leaf by washing out the chlorophyll. If the leaf is not decolorized, you cannot see the blue-black stain that results from the iodine reacting with the starch.
