Fungi
What are the three main groups of fungi?
Yeasts, moulds, and mushrooms.
Some protozoa are sessile. What does this mean?
They do not move. They are attached to rocks or other surfaces using the peduncle.
What type of cells make up algae?
Eukaryotic
What word describes the size of bacteria?
Microscopic
Give an example of a preventative measure to avoid diseases caused by pathogens.
Personal hygiene; wash hands; brush teeth; wash cuts and wounds; keep your house clean; handle and preserve food properly
Fungi can be unicellular or multicellular. How does each type reproduce?
Budding (unicellular) and spores (multicellular).
Most protozoa are free-living. What does this mean?
They do not depend on other living things to survive.
What is the name of the pigment that makes algae green?
Chlorophyll
What shape are vibrio bacteria?
Curved-shaped
What is an autotroph?
Name three roles of fungi.
They are biodegraders; they absorb nitrogen from atmosphere; antibiotics (penicillin); foods (bread); they form lichens
Which group of protozoa move by pseudopods?
Rhizopods
Some algae's habitats are marine. What does this mean?
They live in the sea, mostly attached to the ocean floor.
What do decomposing bacteria do?
Break down dead plant and animal material into simpler substances, which return to the atmosphere/soil and are used again by plants.
What is the name for an organism that feeds off other living things, causing harm or damaging it in the process?
Parasite
Some fungi are saprophytes. What does this mean?
They feed on dead organic material from plants and animals.
What is the name of the malaria parasite?
Plasmodium
This group of algae can form marine forests. Some have air bladders to help them float.
Brown algae
If bacteria cannot reproduce, what is the name of the defensive structure they form until conditions are favourable again?
Endospores
What is the meaning of symbiosis?
The relationship between two living organisms, where both of them benefit from it.
What is a lichen?
Symbiotic association between an algae and a fungus.
Give an example of a flagellate.
Plankton, trypanosome.
What is the name of a unicellular algae that forms colonies of cells?
Volvox
What is the name of bacteria that cause diseases in humans and other living things?
Pathogens
Some organisms reproduce asexually by binary fission. What does this mean?
The organism duplicates its genetic material then separates from one body into two new bodies.
