Nature and variety of living organisms Flashcards
all living organisms do
MRS C GREN
Eukaryotic organisms
Plants, animals, fungi, protoctists
Prokaryotic organisms
Bacteria
Eukaryotes have
nucleus & organelles found within plasma membrane
Prokaryotes have
No nucleus, no membrane-bound organelles
Plants/animal multicellular organisms
Both
Plants/animal chloroplasts+ photosynthesis
Plants
Plants/animal cell wall to strengthen cell
Plants
Plants/animal have nervous co-ordination
Animals
Plants/animal permanent vacuole
Plants(to store cell sap and improve cell rigidity)
Plants/animal can move from one place to another
Animals
Animals store carbohydrate as
Glycogen
Plants store carbohydrate as
Starch/sucrose
Fungi photosynthesis?
No
Fungi body organised into
Mycelium
Mycelium made from
thread like structures called hyphae
Hyphae contain many
Nuclei
Fungi single or multicellular?
Can be either
Fungi Cell walls made of
Chitin
Plant cell walls made of
Cellulose
Fungi feed by?
Saprotrophic nutrition
Saprotrophic nutrition
Extracellular secretion of digestive enzymes onto food materials & absorption of organic products
Fungi may store carbohydrate as
Glycogen
Protoctist size
Microsvopiv
Protoctist single/multi-celled?
Single-celled
Protoctist plant cell/animal cell characteristics
Either
Bacteria size
Microscopic
Bacteria single/multi-celled?
Single-celled
Bacteria
Prokaryotic
Bacteria cell wall made of
Proteins + polysaccharides
