Viruses:



Viruses are particles composed of genetic material, lipids, and a protein wall which protects this material. Unlike bacteria, viruses don't have the ability to grow or replicate on their own. Virologists have said that viruses are not "alive". They require a living host, or a cell to support their replication. They are able to enter a cell and then take over that cell, directing it to make more virus particles. Some viral infections result in the eventual death of the host as in smallpox or rabies, while others allow the host to continue to live even after infection (as with the common cold).

Bacteria:



Bacteria are a successful and ancient form of life, different from the eukaryotes (which includes the fungi, plants and animals). They are small cells, found in the environment as either individual cells or aggregated together as clumps, and their intracellular structure is far simpler than eukaryotes. Bacteria have a single circular DNA chromosome that is found within the cytoplasm of the cell as they do not have a nucleus.

Archaea





Archaea are a group of organisms (not bacteria) that are the environment's natural waste cleaners. Archaea are one fifth the size of bacteria. Archaea attach to the outer membrane of bacteria. They accelerate the breakdown of organic waste and the conversion of some inorganic material to simpler and more stable compounds. (www.bioaeration.com)

Animal Cells:


The cell is one of the most basic units of life. There are millions of different types of cells. There are cells that are organisms onto themselves, such as microscopic amoeba and bacteria cells. And there are cells that only function when part of a larger organism, such as the cells that make up your body. The cell is the smallest unit of life in our bodies. In the body, there are brain cells, skin cells, liver cells, stomach cells.

This, as you can see, is an anatomy of a Animal Cell.


Organelles:


Organelles mean little organs. Basically this means that organelles have specific roles to play in how cells work just like organs help the body function as a whole. Some organelles are separated from the rest of the cell by the lipid bi-layers similar stucture to the cell membrane.

Parts of an organelle:


Cytoplasm
Nucleolus
Nucleus
Vesicle
Endoplasmic reticulum
Golgi apparatus
Cytoskeleton
Mitochondria
Vacuole
Cytosol
Lysosome
Centriole




Function of organelles:



Protection barrier between cell
building and repairing of cell parts
transport of materials
storage and release of energy disposal of waste materials

tigerbc.jpegThe reason I picked this picture is, tigers have been my favorite animal since I was 5. Also, did you know that you can hear a tiger roar over two miles away!! In addition, a tigers expected life span in the wild is eight-ten years. In addition, they are getting hunted by poachers everyday, and are on the verge of extinction so me and my cousin Carly are volunteering at a zoo this summer and have helped raise money to save this beautiful animal. Please, help out this beautiful creature!!!! I would hate to have this beautiful animal extinct.
