| Question | Answer |
|---|---|
| algae | plant like protists |
| amoeboid movement | protoplasmic action of pseudopodia for movement |
| bacillius | rod shaped bacteria |
| cilia | short, hairlike projections used for movement |
| coccus | round shaped bacteria |
| colony | a group of unicellular organisms living together |
| conjugation | reproduction by exchanging genetic material through a tube |
| flagella | long, whiplike projections used for movement |
| fragmentation | reproduction by breakage |
| hyphae | fungal "roots" - secret enzymes for absorption of food |
| lichen | algae and fungus that together as one on trees etc. |
| moneran | one-celled organism without a neucleus includes bacteria |
| mycorrhizae | fungi that help plant roots have nutrients they need |
| parasite | organism that obtains food from a host, is harmful to the living host |
| pathogen | a bacteria or virus that causes a disease |
| protozoa | animal like protists |
| pseudopodia | "false foot" |
| saprophyte | organism that obtains food from dead material |
| spirillium | spiral shaped bacteria |
| spore | reproductive cell of a fungus |
| symbiosis | two organisms working together for each others benefit |
| vaccine | weakened/dead form of a pathogen given to people to help them develop antibodies to fight of the disease |
| Name 3 foods made with bacteria | yogurt, cheese and pickles |
| Symbiotic | Bacteria that live in or on plant or animal tissue with harming the tissue |
| Toxins | What is produced when bacteria spoils food? |
| Name 5 methods of controlling bacteria growth in food. | Sterilization, refridgeraton, pasturization, dehydration, and vacuum packing. |
| antibiotic | Medicine that is made by one organism to kill another kind of organism |
| vaccinations | Protect children from many dangerous diseases. |
| This organism is moving, I notice that it is a single cell, moving with a flagelllum, I cannot tell if this organism has a nucleus or not. Name my classification | Moneran/Protist |
| How are single cell protists more complex than single-celled monerans? | They have a neucleur membrane and they also live in wet enviroments for most of their lives |
| Where do most protists live? | Most protists live in moist we environments |
| How do protists move? | They move by cilia, pseudopodia and flagella |
| Plantlike protists use photosynthesis to make their food. What are two ways in which they are helpful to the environment when they are photosynthesizing. | The release oxygen into the environment. They help reduce air pollution. |
| I just found some lichen growing on the side of a tree in my yard. What is it? | Lichen is two organisms working together. (algae and fungus. Also know as chlorophyta. |
| What might give pudding a smooth texture? | Algin is used in ice cream and marshmellows |
| What does protozoan mean? | proto means first and zoa means animal |
| By what characteristic did scientists decide to classify protozoans? | By how they move |
| What causes the disease known as African Sleeping sickness? | A parasite called Trypanosoma |
| What is a parasite? | Something that lives on a host cell and harms it. |
| Why are fungi not still classified with plants? | because they do not make their own food and they eat after dead things. |
| What kind of habitat do fungi prefer? | Areas that are warm and moist |
| What are two kinds of human diseases caused by fungi? | ringworm and athletes foot |
| How do fungi usually reproduce? | by spores |
| Long filaments of Hyphae | Roots |
| Sexual reproduction in which the contents of one cell pass into another through a tube connecting the two cells | Conjugation |
| How do algae obtain energy? | Photosynthesis |
| What organelle do monera no have? | nucleus |
| How are fungi essential to the natural enviroment? | They help growth |
| Name two decomposer organizms | fungi and bacteria |
| Explain why bacteria do not engulf the earth even though they reproduce rapidly enough to do so. | They need food, oxygen and room tor their waste. Therefore they do not grow more than half the size of a pea. |
| Name 3 ways to protect yourself from pathogens. | wash your hands, avoid sick people, cough into your elbow. |
| Can viruses be classified into one of the 5 kingdoms? | No because they are not a living thing |
| Why are protozoa considered animal like while algae is considered plantlike? | Protozoa can move and Algae cannot |
| Why is Louis Pasteur so important? | Vaccine and Pasteurization |
