The amount of energy that reaches green plants primarily comes from sunlight, with approximately 1,000 watts of solar energy hitting each square meter of Earth's surface on a clear day. However, only about 1-2% of this energy is captured by plants through photosynthesis, which translates to about 20-40 joules per square meter per second. Over a growing season, this can accumulate to several million joules of energy per square meter, depending on the location and environmental conditions.

What does the chorolpaslt do?
A chloroplast produces green pigment called chlorophyll, which turns sunglight into energy that a plant can use. Only certain parts of plants (which are green) have cloroplasts. Roots do not because they cannot reach the sunlight, therefore it has no use for it.
Can plants grow with out sunlight?
Yes, but they will not be as green. Also, plants will naturally grow faster without sunlight in the hope that they will be tall enough to reach sunlight.
How can plants still keep energy without moving?
they grow longer to reach the sun which will give them the energy to grow and produce food
How does the energy from the sun wind up in your dinner?
Plants absorb sunlight through photosynthesis to produce energy in the form of sugars. When you eat plants or animals that have consumed plants, you are consuming this stored solar energy. This energy is then transferred through the food chain to eventually reach your dinner plate.
What is the Name for turning green plants white by lack of light?
The term for turning green plants white due to a lack of light is "etiolation." This process occurs when plants are grown in darkness, causing them to become pale and elongated as they reach for light.
What are the uses of green pigments?
A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. Green Pigments in plants, mainly Chlorophyll is an extremely important biomolecule, critical in Photosynthesis, which allows plants to obtain energy from light. It absorbs mostly blue light and then red light from the Electro-Magnetic Spectrum and reflects Green Light.So, all the plants are green in color and it got a name Green pigment.The green spectrum is dominated by copper phthalocyanine pigments. The common method to reach green is by mixing yellows and blues, the desired brightness and economics being the two main factors determining the best approach. Inorganic pigments play a comparatively insignificant role.
What plant part is not green?
The roots of a plant are not green. A part of a plant is green because it contains chlorophyll, which is used for photosynthesis. Since no light penetrates the ground to reach the roots, the roots need no chlorophyll, and so are brown instead of green.
How much work in joules has been done when you reach the top of the ramp?
The work done is equal to the change in potential energy. If the ramp has a height of h meters, the work done is mgh Joules, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the ramp.
What is a plants growth response away from a light source?
Phototropism is the plant's growth response away from a light source. This natural mechanism allows plants to adjust their growth towards light to optimize photosynthesis. By bending away from light, plants maximize their exposure and energy intake.
How does light energy from the sun eventually reach the decomposers?
Light to green plants ---> photosynthesis to make sugars which are used or stored.Primary consumers eat plants and use the stored energy as energy for growth, movement etc.Secondary consumers eat primary consumers and turn their stored energy into usable energy.Plants, primary consumers, secondary consumers (and the rest) die and are consumed by decomposers who take the stored nutrients and, well, decompose them.The fact that every living thing relies on plant material as a starting point for nutrition, and plants rely on the sun to create that nutrition should answer your question.
Does starch contain nitrogen?
No, starch only contains Carbon, Hidrogen and Oxigen, normally the green leafs of the plants, skin of animals, are reach in nitrogen.
What is a railguns highest amount of kinetic energy?
The slug can reach a velocity of Mach 7, so the amount of kinetic energy depends on the mass of the slug.
