What is a living thing that provides a source of energy for a virus?
100
The type of organism that bacteria are.
What is a prokaryote where the genetic material is not contained in a nucleus? These cells also lack many other organelles.
100
A protist
What is a eukaryote that cannot be classified as animals, plants, or fungi?
100
Definition of fungi.
What are eukaryotes that have cell walls, are heterotrophs that feed by absorbing their food, and use spores to reproduce.
100
A vaccine
What is a substance introduced into the body to stimulate the production of chemicals that destroy specific disease-causing viruses and organism?
200
Parasites
What are organisms that live on or in a host and cause it harm?
200
A long whip-like structure that allows some bacteria to move.
What is a flagellum?
200
A protozoan.
What is a unicellular animal-like protist that is heterotrophic, and usually able to move to obtain food?
200
Hyphae
What are branching, threadlike tubes that make up the bodies of multicellular fungi that allow substances to move quickly and freely through the organism?
200
An endospore.
What is a small, rounded, thick-walled, resting cell that forms inside a bacterial cell and can resist freezing, heating, and drying helping the bacteria survive for many years until conditions become suitable for growing and reproducing.
300
Bacteriophage
What is a virus that infects bacteria? "bacteria eater"
300
The three main shapes bacteria can be.
What is spherical, rodlike, or spiral?
300
The way protozoans are classified.
What is based on the way they move and live?
300
How fungi obtain food.
What is the fungus grows hyphae into the food source, then digestive chemicals ooze from the hyphae into the food, after the chemicals break down the food substances can be absorbed by the hyphae?
300
Five ways bacteria can help people.
What are oxygen production, food production, environmental recycling, environmental cleanup, and health and medicine?
400
The basic structure of all viruses.
What is genetic material surrounding by a protein coat?
400
Conjugation
What is one bacterium transferring some genetic material to another bacterium resulting in bacteria with new combinations of genetic material?
400
Three structures that allow protozoans to move.
What are pseudopods, cilia, and flagella?
400
A fruiting body.
What is reproductive structures where fungi produce spores?
400
Euglena
What is a green unicellular algae (plant-like protist) that can also obtain food from the environment, has a flagellum for movement, can sense light with an eyespot, and move toward that light.
500
The difference between a hidden virus and an active virus.
What is the hidden virus can become part of the host genetic material and after some time the viruses genetic material can remove itself and become active?
500
The three ways bacteria can obtain energy.
What are heterotroph, autotroph using sun energy, or autotroph using chemical energy?
500
A contractile vacuole.
What is a structure that collects excess water inside the protozoan and expels it?
500
The way unicellular yeast cells reproduce asexually.
What is budding?
500
A lichen.
What is a fungus and either algae or autotrophic bacteria that live together in a mutualistic relationship?
