Blue Sky Science: How do plants grow if there''s no sunlight?

They basically create their own food or energy to grow. Plants using photosynthesis will take in carbon dioxide from the air, bring up water from the roots, and use sunlight as the energetic source to create sugar from water and carbon dioxide. Plants contain a molecule called

How do you convert solar energy to thermal energy?

The most common devices used to collect solar energy and convert it to thermal energy are flat-plate collectors. Another method of thermal energy conversion is found in solar ponds, which are bodies of salt water designed to collect and store solar energy.

How much energy does the Sun produce?

If we think about all the wavelengths contained in solar radiation, the total energy output, or luminosity, of the Sun is about 3.86 x 10 26 or 3,860 trillion trillion watts, where a watt corresponds to the energy radiated per unit time.

How do chloroplasts get energy from sunlight?

Then, as other animals eat these plants, the animals are able to get the energy they need from the plant''s stored energy. Answer and Explanation: 1 Chloroplasts get energy from the sunlight with the molecule chlorophyll.

5.1: Overview of Photosynthesis

The Two Parts of Photosynthesis. Photosynthesis takes place in two stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.

How Does the Body Make Vitamin D from Sunlight?

Vitamin D 3 is essential to human health. Its absence leads to a variety of ailments, most notably the bent limbs and weak bones characteristic of rickets. While vitamin D 3 can be obtained through diet, the human body synthesizes it through exposure to sunlight. But how exactly does this happen?
