place a leave in a glass of iodine (brown colour), if it turns the iodine green its means chlorophyll is present. (iodine will evaporate the chlorophyll out of the plant)

Why do you need to remove chlorophyll from a leaf when testing for starch?

Chlorophyll has a function of converting starch into glucose and other simpler plant products.Thats why we have to remove cholorphyll before starting a test for starch.


What are some examples of chlorophyll?

Some examples of chlorophyll are chlorophyll a, chlorophyll b, chlorophyll c1, and chlorophyll c2. These are the most common types of chlorophyll found in plants and algae. Chlorophyll gives plants their green color and is essential for photosynthesis.


What are the different types of chlorophyll What is chlorophyll a and b?

the chlorophyll A and chlorophyll B


What type of chlorophyll does a reaction contain?

chlorophyll a Chlorophyll A


What is two type of chlorophyll?

There is chlorophyll a and chlorophyll b.


Why is variegated leaf used to test to see if chlorophyll is necessary for photosynthesis?

Variegated leaves have patches of green and white due to uneven distribution of chlorophyll. If a variegated leaf is tested by covering the green parts and exposing only the white parts to light, no photosynthesis occurs in the white areas since they lack chlorophyll. This demonstrates that chlorophyll is indeed necessary for photosynthesis to take place.


Why did leaf had to be boiled in ethanol when testing leaf for starch?

Boiling the leaf in ethanol removes chlorophyll, which can interfere with the test for starch using iodine. This process helps to ensure accurate detection of starch in the leaf tissue without any color interference from chlorophyll.


What functional group is different in the identical pigments of chlorophyll a and chlorophyll b?

The functional group that differs between chlorophyll a and chlorophyll b is the aldehyde group on chlorophyll b, which replaces the methyl group on chlorophyll a at the C7 position of the chlorophyll molecules.


What is the difference in the different types of chlorophyll?

There are chlorophyll a and chlorophyll b. in chlorophyll a there is more energy required than in chlorophyll b. chlorophyll a have an absorption peak at 700 nm in contrast to the 680nm of chlorophyll b. chlorophyll a creates a more greener pigment whereas the chlorophyll b has a more yellow appearance of leaves in the fall. there are also other pigments like carotenes which produce the red in autumn.


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.


Which is more polar- chlorophyll a or b?

Chlorophyll a is more polar than chlorophyll b due to the presence of a methyl group in chlorophyll b that increases its overall hydrophobicity, making it less polar compared to chlorophyll a. Consequently, chlorophyll a has a higher affinity for polar solvents and is the primary photosynthetic pigment in plants.


What is the primary pigment in photosynthesis?

The primary photosynthetic pigment that is found in plants is Chlorophyll A. Chlorophyll A is responsible for giving the plants a green appearance.
