This reduction in starch content occurred because starch was changed into simple sugars

<h3>Explanation: </h3>

Starch is a polymeric carbohydrate consist of many glucose units linked by glycosidic bonds. The iodine test is used to test for the presence of starch. Starch will change color to an intense "blue-black" colour after the addition of aqueous solutions of the triiodide anion. To do it we can add Iodine-KI reagent to a solution or directly on a potato or other materials such as bread, crackers, or flour The reaction between amylose that present in lesser amounts and iodine is said to account for the intense color change seen.

An iodine test of a tomato plant leaf revealed that starch was present at 5:00 p.m. on a sunny afternoon in July. When a similar leaf from the same tomato plant was tested with iodine at 6:00 am the next morning, the test indicates that less starch was present in this leaf than in the leaf tested the day before. This reduction in starch content occurred because starch was

  • 1. changed directly into proteins
  • 2. transported out of the leaves through the guard cells
  • 3. transported downward toward the roots through tubes
  • 4. changed into simple sugars

xenn [34]

Answer:

The absorbance of 460nm light by the treatment solutions was the test performed by the student.

Explanation:

Cell membranes are phospholipid bilayers which are mostly displayed by the 'fluid mosaic model' which consists of proteins, carbohydrate polymers and glycoproteins making them able to move around quite freely amongst the phospholipids. A normal membrane permeability test involves investigating the effects of a named variable on the membrane permeability of any vegetable such as beetroot whose biological name is Beta Vulgaris. The variables to investigate are the influence of solvents and temperature because these factors can change the fluidity of the membrane. Beetroot is an important item for this test because of the distinctive betalains pigment that its stem tuber contains. These pigments form an important signal indicating membrane fluidity as they are usually contained in the vacuole of intact beetroot cells. An instant or constant increase in membrane fluidity will cause the pigment to spill out of the cell, and the amount of pigment can be measured simply by using a colorimeter.

The above description is performed under the test of The absorbance of 460nm light by the treatment solutions.
