What is spontaneous generation?
The believe that life spontaneously springs forth randomly
Who disproved spontaneous generation
Louis Pasteur
What properties do all microbial cells share
Compartmentalisation
Growth and reproduction
Evolution
Why are viruses not considered living organisms
They can not grow independently
Lack compartmentalisation
Do bacterial cells have chloroplasts
No, they have chlorophyll and so can photosynthesise, but do not contain any organelles like chloroplast
What is the main component in a bacterial cell wall
Peptidoglycan
Why doesn’t gram-positive/negative staining work well on Archea
They do not contain any peptidoglycan in their cell walls
Are fungi microorganisms
Some fungi, like yeasts, are single celled
What are the 3 categories of algae
Blue green algae
Microalgae
Macroalgae
What are the properties of blue green algae
Prokaryotic
No nucleus
No organelles (like chloroplast)
What are the properties of microalgae
Eukaryotic
Single celled
Microscopic
Contain diatoms and dinoflagellates
What are the properties of macroalgae
Eukaryotic
Multicellular
Macroscopic (big e.g. kelp)
What is an algae
A photosynthetic organism that is not a plant
What are the two types of phototrophs
Anoxygenic
Oxygenic
