variety of organisms Flashcards
multicellular, unicellular...
unicellular
organisms that are made of only one cell 8 bacteria)
multicellular
organisms made out of multiple cells
eukaryotic
cells that have a nucleus
prokaryotic
cells with no nucleus but still have DNA
Heterotrophs
organisms that find food from other sourcesget their nutrients and energy by eating other plants or animals
autotrophs
organisms that make their own food by photosynthesis
saprophytes
Release enzymes which breakdown organic matter into nutrients which can be absorbed eg.fungi
pathogens may include :
fungi, bacteria, protoctists, viruses
what is a pathogen
A pathogen is a disease-causing organism
what are the 5 kingdoms
animals
plant
protoctist
fungi
prokaryots
Prokaryotic organisms
single-celled and do not contain a nucleus
example of prokaryotes
bacteria
are protoctisists large, multicellular ?
no they are single celled and microscopic
protoctist nucleus ?
yes, with a membrane
protoctists have cell walls or chloroplasts ?
some
do protoctists have a nervous coordination
no
are fungi multi or single celled
usually multicellular but can be single
what are fungi made of
thread-like structures known as hyphae that contain many nuclei and are organised into a network known as a mycelium
do fungi have a nucleus
yes
do fungi have walls
yes
fungi cell walls made of ?
Chitin
do fungi carry out photosynthesis
NO
how do fungi feed
secreting extracellular digestive enzymes into food ( saprophotic nutrition)
do fungi have a nervous coordination
no
