Viruses

For millions of years, cells and bacteria have found a common enemy in viruses. These parasitic organisms come in many types and shapes.
Viruses tactics are almost all common. The virus lands on the cell or bacteria and injects its DNA, witch forces the cell to produce new viruses. In seconds, the target bursts and new viruses spread out to inject other cells and bacteria. These viruses spread infection at an alarming rate. It takes valuable recources for the bodies immune system to fight it off.


Bacteria

Bacteria are the smallest of cells. They are prokaryotes,which means that they don`t have a nucleus. They instead have stringy, band like strands of RNA.
Some bacteria cause sickness but some are good like those that help the digestive system.

Archaea435_archaea.jpg

Archaea are a type of prokaryote that are similar in some ways to bacteria.
They are both single cell organisms and they both have the RNA DNA. However, they have different ribosomes than bacteria. Archaea can live in enviorments that no other microbes could survive in. The three types of archaea are heat-loving, salt-loving, and methane making. Heat and salt loving are somtimes called extremophiles. They live in exteme conditions.

Cells

Cells are the building blocks of all life. Each is equipped with all of the building blocks of life. Every plant, animal, or other living thing is assembled from millions of cells that came from former cells. The first cells identified were cork cells. Even as i sit here typing this sentence the millions of cells in my body work constantly to run functions. The cells many organelles work constantly to produce food and energy. The cells protection against the parasidic viruses is the lysosome.













Organelles:

Nucleus: The organelle that holds the DNA of the cell and acts as the cells command center.
Ribosome: The organelle that produces proteins by hooking acids together.
Golgi complex: The organelle that sends items out of the cell.
Chloroplast [plant]: The organelle that uses the suns energy to make food.
Large central vacuole [plant]: The organelle that stores water in a cell.
Endoplasmic reticulum: This organelle sends proteins to the golgi complex and makes lipids.
Mitochondrion: This organelle breaks down food to make ATP.
Lysosome: The organelle that digests food particles and invaders.
Cell membrane: protects the cell.
Cell wall [plant]: Protects the cell and gives support.
Cytoskeleton: provides support.



MantaRay_sholt.jpg

The manta ray is my favorite animal because it is the only ray that is friendly to humans and rarely kept in captivity. Only four have ever been in aquariums. It is a very interesting animal that has developed over many years ways of getting food, and deserves to be the worlds largest ray.
