How do white flowers change colors when food dye is added to the water?
The food dye goes up into the stem of the flower and moves into the system of making the color, creating a different color besides the white on the petals!
Does grass have strong or weak stem?

What makes cassava leaf a good acid-base indicator?
Cassava Leaf Extract as an Acid-Base IndicatorAbstractThis research was conducted to test the feasibility of cassava (Manihot esculenta) leaf extracts as acid-base indicator. There is a growing need to utilize indigenous resources as materials in the laboratory. The results of this study can be a basis for use of cassava, a locally available plant in the country, as an important aid in chemistry.The crude leaf extracts obtained from homogenized cassava leaves were added to chemical compounds with varying strengths in acidity and basicity (strong and weak acids and bases). Color changes were observed and recorded after the application of the extracts. A pH meter was used to determine the ability of the extract to promote color transformation in the different solutions of acids and bases. It was found that extracts from the said plant have the ability to indicate the basicity of a particular chemical substance.IntroductionChemical compounds can be classified as acidic, basic, or neutral substances based on several conditions. One factor considered is the color reaction which can be observed through the use of indicators. An indicator is a substance that changes color, depending on whether it is placed in an acidic solution or basic solution. Acid-base indicators are dyes that are themselves weak acids and weak bases. One indicator that almost everyone associates with acids and bases is the litmus, which has the ability to change color in response to an acid or base. Phenolphthalein is another common indicator used by beginners in Chemistry because its color change is very obvious, making it easy to use. There are many other indicators that change color at different pH levels, and so are useful for different purposes. Another commonly used indicator, the pH paper, contains a mixture of different indicators that change colors at different pH levels. For convenience, many laboratories opt to use pH meters or pH pens.Many plant pigments found in nature can be used quite effectively as acid-base indicators. The dyes in blueberries and red cabbages belong to a family of molecules called anthocyanins. This family of molecules is responsible for the color found in radishes, eggplants, and numerous flowers. The anthocyanins are water-soluble and have colors that are dependent upon the pH of the reacting solution. In this study, the researcher tested the feasibility of Cassava leaf extract as an acid-base indicator. Cassava leaves contain hydrocyanic acid, which is a weak acid.
Cells that retain the ability to divide continuously without specializing are called?
Stem cells are cells that are able to divide continuously without specializing. These kind of cells are undifferentiated biological cells.
Why did your leaf change color?
It all starts in the leaf stem. When the leaf is formed it gets it's nutrients through the stem and passes into the leaf in veins. Then late in the year one of natures little miracles occurs. Leaves are found on hardwood trees that can't support a lot of snow so in the fall. the vein in the leaf stem closes off and starves the leaf of moisture and nutrients causing it to dry out, lose it's color and fall off the tree. With the leaves gone, not as much snow accumulates on the branches and the tree survives. So, if you pull a leaf while it is still green once again it can't get the nutrients it needs and it will die. The color it becomes is dependent upon the type of tree and the pigment that is stored inside the leaf.
