What part of a plant cell is most similar to a solar cell?
Solar cells are not like leaves of plants in almost every fashion. The similarity is that they both get their energy from the sun, however the solar cell gets this energy in a completely different fashion when compared to a leaf.
Why is solar energy a clean form of energy?
Solar energy is claimed as a clean form of energy as no carbon dioxide or nitrogen and sulfur oxides are produced during the operation of solar plants or solar cells (as is the case when using fossil fuels as coal, oil, or natural gas). However, solar energy is not absolutely clean if we look to the overall solar cycle including the production of solar cells or mirrors as well including the decommissioning of these solar plants or cells. Around 50 toxic elements are included in the production of solar cells or mirrors. In this regards, nuclear, wind, and hydro-electric power plants are even cleaner than solar power plants.
What captures solar energy and uses photosynthesis to produce sugars?
Plants do this in the chloroplasts in their green leaves.
In which part plant trap solar energy?
Plants trap solar energy in their leaves through a process called photosynthesis. Photosynthesis occurs in specialized cells within the leaves called chloroplasts, which contain chlorophyll, the pigment that captures sunlight and converts it into chemical energy for the plant to use.
What is the substance in leaves that gives them their green colour?
The green color is caused by chlorophyll present in the chloroplasts of the leaf cells. Chloroplasts are found in plant cells; they have a green pigment which makes leaves green. In autumn, the leaves turn red and brown because the cells are dried out and dead. Chloroplasts trap solar energy (photosynthesis).
How do plants get there green color from what chemical?
Plant leaves contain chlorophyll in its chloroplasts in mesophyll cells which make plant leaves green. Chlorophyll helps in photosynthesis by absorbing solar radiation for photolysis of water molecules.
What are positives and negatives about solar power?
Some positives:It provides "free" energy.It is clean as it leaves no carbon footprint.Some negatives:Current solar cells are inefficient in converting light to electricity.
Why does a plant tilt its leaves upwards at noon time?
Plants are heliotropic, that is they have the ability to move in order to maximize the amount of solar radiation that they absorb - think of it as moving solar panels.
Why is it that generally the leaves of plants is color green?
Because plants use chlorophyll to photosynthesize energy from solar radiation and chlorophyll is a bad absorber of light's green wavelengths.
Explain some of the limitations of solar energy?
solar energy is available only when the sun is shining. Solar collectors and cells work less efficiently on cloudy days. they don't work at all at night. and during winter, when days are short, the collectors and cells generate less energy.
where can you buy solar cells?
where can you buy solar cells
How are the ways in which solar cells and plants capture sunlight and convert it into other forms of energy different?
to they eat the people .
