Life Science Outline
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.
Viruses even look bad
(This is a short video that describes the different kinds of viruses and how a virus infects a cell.) Viruses always confuse me. They're not alive but they still do stuff, and how do they do stuff? They don't use energy so what do they use? Magic?
Bacteria
Life Science Outline
(This is a picture of Staph bacteria.)
Bacteria are small single celled organisms that have a cell wall and do not have a well, defined nucleus. They are the cause of many sicknesses.
Archea
Checklist
.
(This is a picture of an Archea)
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.
Animal Cell
Do animal cells really have hairs like that?
(This is a diagram of an animal cell and its organelles)
This is a diagram of an animal cell, and yes, animal cells are different then plant cells. Just look at the differences between the animal cell diagram above and the plant cell diagram underPlant Cell.
Animal Organelles
(HowStuffWorks, biology online) Cell Membrane: acts as selective boundaries within the environment, allowing food, oxygen, and carbon dioxide to pass through Cytoskeleton: helps cells retain shape and move Nucleus: directs the life activities of a cell Ribosome: contain the information for making new proteins Endoplasmic Reticulum: serves as a site for protein production and provides a transport route within the cell. Mitochondrion: provide for the energy needs of the cell Golgi Complex: forms vesciles and modifies protiens and lipids for transport Vesicle: stores and transports cellular products, and digests metabolic wastes within the cell Lysosome: breaks down food into smaller molocules inside the animal cell
Plant Cell
Some of the differences between plant and animal cells are in the structure (organelles), as you can see. Organelles are are things inside the cell that perform a certain job, sort of like our organs. One of the reasons why they have different organelles is the way they get energy. Plant cells use photosynthesis and animal cells have to find and break down food.
(This is a diagram of a plant cell and it's organelles)
Plant Organelles
(HowStuffWorks) Cell Wall: helps provide support in a plant cell Chloroplast: turns sunlight into energy during photosynthesis Large Central Vacuole: stores water and other liquids Photosynthesis: converts sunlight into energy
Are penguins really birds? Seriously, they can't fly but they but they can swim.
I think that either a scientist or mother nature made a mistake in naming them.
