Diversity Flashcards
(23 cards)
Protista
- unicellular and multicellular
- Terrestrial and aquatic
- Eukaryotic
- Autotrophic and heterotrophic
Animal like protists
Sarcodines
Flagellates
Ciliates
Sporozoans
Sarcodines
Amoebic movement
Feed by phagocytosis, pseudopod engulfs food particles
Ex. Amoeba
Flagellates
Have flagella
Live in fresh water or other organisms
Ex. Euglena
Ciliates
Hair like structures
Reproduce asexually by binary fission
Sexually by conjugation
Ex. Vorticella
Sporozoans
Parasitic
Complex life cycles
Ex. Malaria
Plant like protists
Autotrophic-contain chlorophyll
Unicellular or multicellular
Ex. Algae
Fungus like protists
Referred to as slime moulds
Most are saprotrophic
Fungi
Eukaryotic Live in soil,air, other organisms Heterotrophic Cell wall composed of chitin Unicellular or multicellular 3 types - mushrooms -yeast -mould
Fungi reproduction
Sexual and asexual
Archea
Live in extreme environments
Plants
Eukaryotes
Autotrophs
Terrestrial and aquatic
Alternation of generations
Bryophyte
First to move to the land
Ferns
First to have vascular tissues
Gymnosperms
Conifers; the have seeds
Angiosperms
Have flowers
Animalia
Eukaryotes Multicellular Moveable Heterotrophic No cell wall
Eubacteria
Single celled
Prokaryotes
Shape of bacteria
Spherical- cocci/coccus
Rod shaped - bacilli/bacillius
Spiral - spirilla/spirillium
Arrangement of bacteria
Diplo- groups of two
Staphylo- clusters
Strepto- chains
Asexual reproduction bacteria
- Cell elongates and DNA replicates
- Cell wall me membrane begin to divide
- Cross-wall forms completely around divided DNA
- Cell separates
Conjugation bacteria
- Two bacteria decide to reproduce
- The bacteria with mobile plasmid sends out a pilus
- The mobile plasmid sends some chromosomes to the other bacteria via the pilus
- The pilus de attaches and now both bacteria came reproduce
Transformation bacteria
- Bacteria finds fragmented DNA donor cells
- recipient cell takes up donor DNA
- Recombination occurs between donor DNA and recipient DNA
