More than merely a clever collaboration that has endured between some of the tiniest ocean animals and plants for some 25 million years, this mutual exchange is the reason why coral reefs are the largest structures of biological origin on Earth, and rival old-growth forests in the longevity of their ecological communities.
Corals actually comprise an ancient and unique partnership, called symbiosis, that benefits both animal and plant life in the ocean. Corals are animals, though, because they do not make their own food, as plants do. Corals have tiny, tentacle-like arms that they use to capture their food from the water and sweep into their inscrutable mouths.
, Mother Jones reported on malnourished raccoons, , and bats left for dead behind the scenes of Animal Planet's hit show Call of the Wildman. During a seven-month investigation, we discovered that the show's producers routinely sourced trapped wildlife to perform roles in heavily scripted "rescue" scenes.
All animals and plants are made of cells. Animal cells and plant cells have features in common, such as a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes. Plant cells also have a cell wall, and often have chloroplasts and a permanent vacuole. Note that cells may be specialised to carry out a particular function.
|nucleus||contains genetic material, which controls the activities of the cell|
|cytoplasm||most chemical processes take place here, controlled by enzymes|
|cell membrane||controls the movement of substances into and out of the cell|
|mitochondria||most energy is released by respiration here|
|ribosomes||protein synthesis happens here|
