Bacteria
Are bacteria prokaryotes or eukaryotes? What does this mean
Prokaryotes; they do not have a nucleus
The protein coat that surrounds a virus’s genetic material is called this.
Capsid
All protists share this trait:
Eukaryotes
How do fungi reproduce?
Spores
This whip-like structure helps some bacteria move.
Flagella
Viruses may contain one of these two types of genetic material surrounded by a capsid.
DNA or RNA
Protists are classified based on
Structure
How are fungi heterotrophs if they don't have mouths or an oral groove?
They release digestive enzymes into the area around them and absorb the nutrients using their mycelium hyphae
This process is how bacteria reproduce by splitting into two identical cells.
Binary fission
How do viruses reproduce?
Hijacking a host cell and using its organelles to make copies before bursting out, killing the host cell.
These protists use pseudopods, or “false feet,” to move.
Amoeboid
Fungi that feed on dead organisms are called
Saprophytes
What are plasmids and how do bacteria use them?
Small pieces of DNA separate from the main chromosome used to share genes between bacteria
Why are viruses not considered living things?
They are not made of cells and cannot reproduce on their own
What is the difference between the structures heterotrophic protists and autotrophic protists use to eat?
Heterotrophs use an oral groove and autotrophs use photosynthesis in the chloroplast
Why is a fungi not considered a plant?
Fungi are heterotrophs and have cell walls made of chitin; plants are autotrophs and have cell walls made of cellulose
CHALLENGE: Why should you take ALL of the antibiotics your doctor prescribes?
Some bacteria could be resistant and share plasmids with the resistant to gene to other surviving bacteria, making the antibiotic useless in the future
What is a benefit of a virus being latent?
Can make more copies of itself before infecting and spread to more organisms
CHALLENGE: Give an example of a protist who uses cilia to get around (HINT: live in water and typically harmless)
Paramecium
CHALLENGE: What substance is produced when there is symbiosis between algae and fungus
Lichin
