You would test the leaves of the plant for starch. Starch is produced through photosynthesis in the leaves, so they are the best part of the plant to test for the presence of this carbohydrate.
Other parts of the plant, such as the roots, would likely test positive for starch because they often store energy in the form of starch. Roots, like tubers (e.g., potatoes), are specialized for carbohydrate storage, allowing the plant to utilize this energy during periods of growth or when photosynthesis is not possible. Additionally, stems can also store starch, especially in certain plants where they function as storage organs.
The genotype of the plant with colored seed and normal starch in the test cross would be AaBb. This genotype indicates that the plant is heterozygous for both the color gene (A) and the starch gene (B), with the recessive alleles for both traits being a (for color) and b (for starch).
Testing for the presence of starch is commonly done in biology and food science to detect the presence of carbohydrates. Iodine solution is typically used for this test, as it turns blue-black in the presence of starch. This test can be useful in identifying starch in foods or in plant tissues.
the answer to tis would be iodine because it is uses in the method to test for presence of startch in a leaf
To test for starch, you will need iodine solution and the sample you want to test. The iodine solution will react with the starch to produce a blue-black color, confirming the presence of starch in the sample.

leave it in sunlight and water it, use a starch indicator to test presence of starch, or put an aquatic plant in a beaker of water and put a test tube upside down in the beaker surrounding the plant and leave it in sunlight and you should eventually see oxygen bubbles start to form up from the plant through the test tube

The iodine starch test is a chemical test used to detect the presence of starch in a solution. Iodine reacts with the starch molecules to form a blue-black color complex, indicating the presence of starch. This test is commonly used in biology and chemistry laboratories to identify the presence of starch in foods and plant materials.

The project is on necessity of light for photosynthesis. Therefore, iodine solution is needd to test the formation of starch in the plant kept in light by photosynthesis. The plant kept in dark will show the absence of starch meaning there by no photosynthesis has taken place in dark.
put a few drops of iodine on the subject, if it turns purple theres starch.

Yes, distilled water would test negative for starch. Starch can only be detected through specific chemical tests that involve reagents like iodine solution, which would not react with distilled water.
Hydrolysed starch would test negative in iodine testing because hydrolysis breaks down the starch into smaller sugar molecules like glucose, which no longer have the characteristic branching structure of starch that allows iodine to bind and form a blue-black complex. Therefore, with hydrolysed starch, there would be no starch molecules left to react with iodine and show a color change.
The iodine test is commonly used to detect the presence of starch in a sample. If the leaf turns blue-black when treated with iodine solution after boiling with ethanol, it indicates the presence of starch in the leaf tissue.
