Some humans have traveled from Earth to Pandora because it is a source of a very valuable mineral called unobtanium. The largest deposit of the mineral is under a large tree that the local Na'vi people have named "Hometree" ("kelutral" in the Na'vi language). The tree is very important to the Na'vi. Parker Selfridge (played by Giovanni Ribisi) is the military leader of the mining operation. He uses marines for security. The marines need to move the Na'vi people before they can start mining the unobtanium. They have tried to do this many times. They have offered the Na'vi clothing, education, and such, but none has been working. Their next plan is to just blow the place up.
Pandora is inhabited by the Na'vi. They are a blue-skinned species of humanoids with feline characteristics. Physically, the Na'vi are much stronger and taller than humans. They live in harmony with Nature and worship a mother goddess called Eywa. The human scientists on Pandora want to learn about the Na'vi's culture. To do this, they have created "avatars". Avatars are Na'vi bodies modified with human DNA. They are controlled mentally by human operators. These avatars are used to interact with the Na'vi people, to try to create peace. Jake Sully (played by Sam Worthington) is a paraplegic marine . His brother was a scientist trained to be an avatar operator. After his brother dies, Jake replaces him to control his avatar. Jake receives the mission to form relations with the Na'vi. His goal is to get the Na'vi to move away from Hometree so the humans can mine for unobtanium there. To do this, he was to become friends with the Na'vi so he could learn what it would take to get them to move. Many people, like Grace (played by Sigourney Weaver), an avatar specialist, did not think Jake had enough experience and intelligence to be useful. On a mission in avatar form, he gets lost in the jungle.
Jake's avatar is saved by Neytiri (Zoe Saldana), a female Na'vi. Neytiri takes Jake to Hometree, where her clan, the Omaticaya, live. As a shaman, Neytiri's mother shows interest in Jake. She asks her daughter to teach Jake about their culture. Together, Jake and Neytiri have many adventures in Pandora. Neytiri shows Jake the spirit that every living thing has. Jake is respected when he first comes to the Na'vi. They call him a "sky-dreamer". Once he learns their culture, he impresses all of them and earns their respect. He becomes a member of the Omaticaya clan and is seen as one of them. At first, Neytiri does not like him. Their friendship forms as he becomes more skilled and her equal. They mate under the tree of Eywa. At first, Neytiri's father is quite mad about it. Over time, he accepts it.
Time passes and Jake has not gotten the Na'vi people to move. Park Selfridge sees this. He tells Jake that it has taken too long and that they are going to bomb Hometree. Jake tries to warn the Na'vi people. The Na'vi people feel that he has betrayed them because he knew this was going to happen. The Na'vi try to fight back but their bows and arrows are useless against the Marines. The Hometree is bombed and thousands of Na'vi people died. Neytiri's father is one of the dead. Jake and Grace have failed. They are jailed by the mining company because they fought with the Na'vi.
With the help of a woman marine pilot named Trudy (played by Michelle Rodriguez), they escape in a helicopter. They go to a nearby base to change into avatar mode. They then go to Hometree to see the Na'vi. Jake tells the Na'vi people that they still must fight. He joins with one of the Na'vi warriors to train them. Soon, more Na'vi come to defend their land. The marines choose to just destroy the Na'vi rather than try and move them. Many people do not think this was right. They think it is inhumane. These people are not listened to and the Marines went to attack the Na'vi. There is a very large battle between the Marines and Na'vi. When it looks as if the marines are going to win, many of the animals of Pandora join the battle. They fight with the Na'vi against the marines. Near the end of the battle, Jake, in his avatar, fights Parker Selfridge. When he is almost dead, Neytiri saves him. The Na'vi eventually win but many die. After the battle, the Marines are sent home to planet Earth. Jake Sully is changed into his avatar permanently and becomes the leader of the Na'vi with Neytiri.
If Cameron was inspired by every science fiction book he read when he was a kid, the look of the Na'vi was inspired by a dream that Cameron's mother had before he wrote Avatar. She dreamt about a 12-foot-tall blue woman and he thought that image was cool.
Cameron's aim was to make us think about how we interact with nature and others . Cameron said: "the Na'vi represent(...) our higher selves, or our aspirational selves..." and the humans represent "the parts of ourselves that are trashing our world and maybe condemning ourselves to a grim future".

Paramecium
Paramecium is one of the best-known protists, often taught in school biology courses. It is a ciliate genus. Ciliates are a clade of protists which move by synchronous waves of tiny projections from their cuticle. These projections are called cilia (singular: "cilium"). The species range from 50 to 350 μm in length. They live in freshwater ponds, and eat bacteria, and other protists such as single-celled algae.
Paramecium species usually have bacterial symbionts, and some species have green algal symbionts.
Reproduction in "Paramecium" has been researched for many years.
"Paramecium" has two nuclei (a large macronucleus and a single compact micronucleus). They cannot survive without the macronucleus and cannot reproduce without the micronucleus. Reproduction is either by binary fission (asexual), conjugation (sexual), or, rarely, by "endomixis", a process of self-fertilisation. During binary fission a fully grown organism divides into two daughter cells. Conjugation consists of the temporary union of two organisms and the exchange of micro-nuclear elements. Without the rejuvenating effects of conjugation a paramecium ages and dies. Only opposite mating types, or genetically compatible organisms, can unite in conjugation.
This reproductive system is unique to ciliates, and is one of the reasons why we think the Protista is not a natural clade (monophyletic), but rather a polyphyletic collection of single-celled organisms.
This species consists of 14 "syngens", each genetically isolated from every other, and biochemically unique. Each syngen has two mating types. The syngens are so similar in appearance that they have not been given separate species names.
These are paramecia which secrete, into the medium around them, particles which kill other paramecia. This killer trait is caused by kappa particles, which are are symbiotic bacteria. The kappa particles are only found in paramecia with a dominant K gene. The killing is done by smaller particles which are defective DNA phages. The kappa bacterium is just one of many found in natural populations of "Paramecium aurelia".
