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.
The Hubble Space Telescope (HST) is the most famous-and probably most successful-space observatory ever flown. The 11 tonne telescope was placed into a 570 km high orbit around Earth by the Space Shuttle in April 1990. Circling our planet every 96 minutes, the HST has so far travelled some 5 billion km. Hubble has sent back a huge amount of scientific data and incredibly detailed images of every type of object in the sky. By autumn 2009, it had made nearly 900,000 observations and snapped over 570,000 images of more than 29,000 objects.
