Tori toritf Viruses
A virus is a microscopic particle that often destroys the cell. In other words they are the stuff that makes you sick. They can cause diseases such as the common cold, the flu, and many other medical problems. Below is a diagram of a virus. (Holt Life Science)
Bacteria
Did you know that a handful of soil on average carries 2.5 billion bacteria. Bacteria are prokaryote cells, which means it does not have a nucleus, and have no membrane covered organelles, but they do have ribosomes. (Ribosomes are round organelles made of protein.) (Holt Life Science)
Archaea
Archaea is also a prokaryote cell and also like bacteria, is a single celled organism. Archaea have ribosomes, but they are a little bit different. There are 3 different types of archaea. They are heat-loving, salt-loving, and methane-loving. Below is an archaea bacteria. (Holt Life Science) Animal Cell
A cell is the smallest unit that can perform all of life's process's. All cell's are covered with a cell membrane and contain DNA with cytoplasm. Here is a diagram of an animal cell with the labeled organelles and other parts. Animal Organelles
A body in a cell cytoplasm that are specialized to perform a specific function, and different cells have different types of organelles. These organelles float in the cytoplasm and most organelles are surrounded by membranes. The major organelles of an animal cell, are the Nucleus, Ribosome, Endoplasmic Reticulum (a.k.a. ER), Mitochondrion, Golgi complex, and Lysosomes. Here are their functions:
Cell Membrane- a phospholipid layer that covers a cell surface while acting like a barrier between the inside and outside of a cell Cytoplasm- Nucleus- contain the cell's DNA and be the center control center of a cell Ribosome- make proteins using amino acids ER- makes lipids, breaks down substances, and packages protein for the Golgi complex Mitochondrion- the organelle that makes ATP by breaking down food molecules Golgi Complex- transports and processes materials and proteins out of the cell Vesicle- Lysosome- digests waste, cell parts, food particles, and foreign invaders
Plant Cell A plant cell
Plant Cell Organelles Cell Wall- the structure that surrounds the cell Chloroplast- makes food using energy from the sunlight using a process called photosynthesis, these are found in plant cells Large Central Vacuole- stores water and other materials and is found in plant cells Photosyntesis- For a review here is the official definitions of a virus, bacteria, and archaea!
A virus is nonliving structure that attacks cells and multiplies by injecting RNA or DNA telling the cell to make multiple copies of the virus.
Bacteria are small single celled organisms that have a cell wall and do not have a well, defined nucleus.
Archea are small single celled organisms that have a cell wall and do not have a well, defined nucleus. Archea very similar to bacteria but have a different ribosome structure and tend to be extremophiles. Extemophiles can live in extreme conditions such as high and low temperatures.
Now here is a short movie about viruses, bacteria, and archaea. I hope you enjoy and try to learn stuff about science too. Have fun!
Polar bear are really cute! Look at them they are just so exciting!!! Did you know that polar bears are in danger because of melting ice in the arctic circle? Did you know that you might be doing this? STOP GLOBAL WARMING!!!!!

Ribosome- make proteins using amino acids
ER- makes lipids, breaks down substances, and packages protein for the Golgi complex
Mitochondrion- the organelle that makes ATP by breaking down food molecules
Golgi Complex- transports and processes materials and proteins out of the cell
Vesicle-
