| Why do we need to know about bacteria ? | They are all around us they are invisible forms of life some help us some can hurt us and make us sick ! |
| Who discovered bacteria and what did he use ? | The scientist that discovered bacteria also invented the microscope and his name was Anton van Leeuwenhoek. Need to use microscope to see bacteria. |
| What is a prokaryote ? | A cell that does not have the genetic material in a nucleus. |
| How many shapes are bacteria in ? | They are shaped like balls(spheres), rods or spiral shaped ? |
| What is the cell wall? | The strong outer most surface of a bacteria.It covers the membrane. |
| What is the cell membrane ? | Lets food in and waste leave the cell. |
| What is the cytoplasm ? | The gel like material inside the cell. |
| What is the ribosome ? | The factory for making the proteins the cell needs. |
| What is the flagellum ? | It is the whip like structure that sticks out of cell wall and helps bacteria move. |
| What are the two major kingdom of Bacteria ? | Arachaebacteria and eubacteria. |
| What are arachaebacteria ? | Oldest forms lived a billion years ago live in very sever conditions hot springs and salt water . |
| What are eubacteria ? | The ones that are almost everywhere on earth. They help make the oxygen we breathe. |
| How long does it take a bacteria to make more bacteria ? | Very fast .. some in 20 minutes. |
| How do bacteria reproduce ? | Use binary fission:split in asexual reproduction.One parent makes a copy of iteslf and another identical child. |
| Do any bacteria reproduce by sexual reproduction ? | Yes they do they use a conjugation reaction where they share their genetic material then they use binary fission to produce offspring that are different from themselves. |
| What is an autotroph ? | It makes its own food ! |
| What are heterotrophs ? | They get food by eating other things . |
| How do bacteria get energy ? | They use respiration, which means breaking down food to get energy! |
| How do bacteria survive when conditions are bad ? | Some form small balls of genetic material called endospores. |
| What is an endospore ? | Cytoplasm and genetic material iside a thick walled part of a bacteria. |
| What are some of the good things bacteria will do for us ? | Make food, Make oxygen, make medicines,help recycle. |
| What gas do bacteria make ? | Methane : used in our homes called natural gas. |
| What foods do baceria make ? | They change milk into yogurt and cheeses. |
| What are ways that bacteria recycle ? | Some can make toxic chemicals into nontoxic things. |
| Do some plants use bacteria to recycle ? | Yes they take nitrogen from are and make food for the plant to use. |
| How do bacteria make medicines ? | Scientist put the genetic information for some proteins we use as medicinen into bacteruia. Then they grow bacteria to make a large ammount of the protein. This is how insulin is made for diabetic patients. |
| What is a disinfectant ? | A chemical that rapidly kill bacteria. |
