HELP with a photosynthesis problem??

Question

Under which color filter will the leaf produce more starch; red, blue, green or white????


HOw can I know this? Is it the wavelenghts?


Can Someone explain to me why would the leaves under the [blank] colors will produce more starch??

Answer 1

The plant will function better under white light i think because it will recieve all the light it needs and reflect the unnescessary light
or if there was no white it would work better with red and blue because it would reflect green back... it would barely work under green light

Answer 2

i learned this at school but it was some time ago so i can only describe briefly and i hope that will help at least a little. and for you to do further research on subjects matter.

photosynthesis needs light to provides energy for an electron transport chain. this light energy is absorbed by a special molecule in chlorophile called photocytochrome. photocytochrome absorbs light of different wavelengths at different affinity. more light is absorbed in red-blue spectrum (i need to confirm this) so more energy for molecular reactions forming more starch

Answer 3

Photosynthesis relies on chlorophyll. It is the wavelengths of light that chlorophyll abosorbs that should explain which colour filters will produce more starch. Check the absorbtion curve at

Answer 4

Well it is process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose.
Most plants produce more glucose than they use, however, and they store it in the form of starch and other carbohydrates in roots, stems, and leaves.
Photosynthesis is a very complex process, and for the sake of convenience and ease of understanding, plant biologists divide it into two stages. In the first stage, the light-dependent reaction, the chloroplast traps light energy and converts it into chemical energy contained in nicotinamide adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP), two molecules used in the second stage of photosynthesis. In the second stage, called the light-independent reaction (formerly called the dark reaction), NADPH provides the hydrogen atoms that help form glucose, and ATP provides the energy for this and other reactions used to synthesize glucose. These two stages reflect the literal meaning of the term photosynthesis, to build with light.
Plant photosynthesis occurs in leaves and green stems within specialized cell structures called chloroplasts. One plant leaf is composed of tens of thousands of cells, and each cell contains 40 to 50 chloroplasts. The chloroplast, an oval-shaped structure, is divided by membranes into numerous disk-shaped compartments. These disklike compartments, called thylakoids, are arranged vertically in the chloroplast like a stack of plates or pancakes. A stack of thylakoids is called a granum (plural, grana); the grana lie suspended in a fluid known as stroma.
Carbon Cycle
Photosynthesis plays a crucial role in the carbon cycle. Carbon continuously circulates in the earth’s ecosystem. In the atmosphere, it exists as colorless, odorless carbon dioxide gas, which is used by plants in the process of photosynthesis. Animals acquire the carbon stored in plant tissue when they eat and exhale carbon dioxide as a by-product of metabolism. Although some carbon is removed from circulation temporarily as coal, petroleum, fossil fuels, gas, and limestone deposits, cellular respiration and photosynthesis balance to keep the amount of atmospheric carbon relatively stable. Industrialization, however, has contributed additional carbon dioxide to the environment.
Embedded in the membranes of the thylakoids are hundreds of molecules of chlorophyll, a light-trapping pigment required for photosynthesis. Additional light-trapping pigments, enzymes (organic substances that speed up chemical reactions), and other molecules needed for photosynthesis are also located within the thylakoid membranes. The pigments and enzymes are arranged in two types of units, Photosystem I and Photosystem II. Because a chloroplast may have dozens of thylakoids, and each thylakoid may contain thousands of photosystems, each chloroplast will contain millions of pigment molecules
