PROTISTS
What are PROTISTS?
Protists are eukaryotes(have a true nucleus),can be animal-like(consumers)or plant-like(producers)
What is CHITIN?
A hard substance that makes up cell walls of fungi(its also in insects exoskeleton
What is HYPHAE?
Tiny threads of cytoplasm surrounded by a plasma membrane (basic cells)
How are prokaryotes identified?
Their shape, lack of nucleus, cell wall, how they get their energy.
How do viruses reproduce?
By infecting living cells.
How do different protists move in their environment?
Flagella-are long and whip-like(only a couple)
Cilia-short hair(many of them)
pseudopods-fake foot
Explain the structure of the body of a typical fungus.
Hyphae, Mycelium, and Chitin
What is MYCELIUM?
A mass that the hyphae of a fungus branch forms(a bunch of hyphae working togethe)
What is the function of flagella?
To propel bacteria’s; movement.
Compare a lytic infection to a lysogenic infection.
Lytic causes the cell to burst
Lysogenic is involved with the DNA of hosts
Identify characteristics of fungi.
produces spores, and decomposers-breaks things down
Identify characteristics of club fungi.
Produces spores in club-like structures
example:mushrooms and puffs
What is a VIRUS?
A particle of nucleic acid, protein, and in some cases liquid; can only reproduce by infecting living cells
What is a binary fission?
A process that involves one parent that divides into two identical cell copies of reproduction.
What is a retrovirus?
A group of viruses that contain RNA that produces a DNA copy of their RNA that does not have DNA.
What disease is causes by bacteria?
Salmonella
