C3 vs C4 Plants. Photosynthesis is the light driven reaction that converts carbon dioxide and water in to energy rich sugars. The process is coupled to the oxidation of water yielding oxygen as a biproduct.4 plants are much more efficient at capturing carbon dioxide. C4 photosynthesis is found in both monocot and dicot species. In contrast to C3 plants, the first stable product formed during photosynthesis is oxaloacetic, which is a C4 compound.
The Gran Telescopio Canarias is by far the largest telescope on earth and measures 34 feet (or 409 inches) across! Its home is in the Canary Islands of Spain. The design and development of this telescope took more than 1,000 people from over 100 companies more than a decade to complete.
Many celestial phenomena can be seen at more than one wavelength. 1  Optical telescopes can be used on Earth and in space. An example of a huge optical telescope in space is the Hubble Space Telescope through which astronomers can look out across the Universe without the distortion of light by the Earth's atmosphere. The first optical telescope was created 400 years ago, while the other kinds of telescopes were invented in the 20th century.
