Image result for the light harvesting complexThe antenna pigments are predominantly chlorophyll b, xanthophylls, and carotenes. Chlorophyll a is known as the core pigment. Their absorption spectra are non-overlapping and broaden the range of light that can be absorbed in photosynthesis. The carotenoids have another role as an antioxidant to prevent photo-oxidative damage of chlorophyll molecules. Each antenna complex has between 250 and 400 pigment molecules and the energy they absorb is shuttled by resonance energy transfer to a specialized chlorophyll-protein complex known as the reaction center of each photosystem.[1] The reaction center initiates a complex series of chemical reactions that capture energy in the form of chemical bonds.

Taiga ecosystems

Image
Location of the Taiga Ecosystems The  taiga  is the largest biome. The  taiga  is primarily a coniferous forest (evergreen trees with needles) like the temperate rainforest, but the  taiga  is  located between 50 degrees latitude north and the Arctic circle. The  taiga  is a forest of the cold, subarctic region. The subarctic is an area of the Northern Hemisphere that lies just south of the Arctic Circle. The  taiga  lies between the tundra to the north and temperate forests to the south. Alaska, Canada, Scandinavia, and Siberia have Taiga. Climate The  taiga  is the terrestrial biome with the lowest annual average temperatures after the tundra and permanent ice caps. ... The  taiga  or boreal forest has a subarctic  climate  with very large temperature range between seasons, but the long and cold winter is the dominant feature. Plants There are some lichens and mosses, but most  plants ...

TADPOLE GALAXY Skylar & Azalea

Image
The Tadpole Galaxy is a disrupted barred spiral galaxy located 420 million light-years from Earth in the northern constellation Draco. It's most dramatic feature is a massive trail of stars about 280,000 lights-years long; the size of the galaxy has been attributed to a merger with a smaller galaxy that is to have occurred about 100 million years ago. The galaxy is filled  with bright blue stars cluster.          Its is hypothesized that a more compact intruder galaxy crossed in front of the Tadpole Galaxy-from left to right from the perspective of Earth - and was slung around behind the Tadpole by their mutual gravitational attraction. During this close encounter,tidal forces drew out the spiral galaxy's starts, gas, and dust, forming the conspicuous tail. The intruder galaxy itself, estimated to lie about 300 thousand light-years behind the Tadpole, can be seen through foreground spiral arms at the upper left. Following its terrestrial namesake, the Ta...

River and Streams by Yuridia and Briana

River and Stream Ecosystem in this ecosystem we are going to talk about river and stem ecosystem.it will talk about all sorts of plants and animals Animals : Some of the animals that live in the river or streams are  turtles, ducks, otters, crocodiles, catfish, drag on fly and crabs can be found in  rivers  all around the world, and the Amazon river is even home to the rare and pink, freshwater dolphin. an d for your information we are talking about all rivers and streams   climate: Rivers change their course as they travel and carve a path through the land.  The temperatures range from 65 °F to 75 °F in the summer and 35 °F to 45 °F in the winter. plants: Rivers and streams  are fresh water and hold up to 3 percent of the Earth's fresh water. Freshwater  plants  include algae, bulrushes and cattails, and freshwater animals include crayfish, fish and eels. location: Rivers /  Streams : A...
