1
Q

richness and abundance of taxa

A

Richness - there are many different taxa

Abundance - there are large numbers of non-human organisms

2
Q

Why study non-human taxa?

A
• study disease
• food source
• medicine 
 - leeches
 - inspiration for technological advancements
3
Q

What kingdoms use the the organelles; chloroplast and mitochondria?

A
  • Protista
  • Plantae

only mitochondria
• Fungi
• Animalia

4
Q

Heterotrophic vs autotrophic kingdom

A

Heterotrophic
• fungi
• animalia

Autotrophic
• protista (or heterotrophic)
• plantae

5
Q

Acronym to remember taxonomy categories?

A

King penguins can only fly going south

  • kingdom
  • phylum
  • class
  • order
  • family
  • genre
  • species
6
Q

define species

A

a group of organisms that can mate with one another to produce fertile offspring

7
Q

Writing genus and species

A

Genus should be capitalised and whole thing (both genus and species) underlined/italicised

Homo - genus
sapien - species

8
Q

How do you determine if an organism is closely related?

A
  • organisms of the same genus are closely related

* organisms that share a species name are not closely related (e.g. cuttlefish, fish not related)

9
Q

Phylum porifera

A
  • ‘pore bearing’ so sponge

* no symmetry

10
Q

Phylum Cnidaria

A

‘stinging thread’ - jellyfish

  • class cubozoa
  • class hydrozoa
11
Q

Class hydrozoa

A
  • blue bottle jellyfish
  • first aid - hot water
  • single opening - mouth/anus
12
Q

Class cubozoa

A
  • first aid - vinegar or hot water
  • complex lens eyes
  • contain toxins
13
Q

Diploblastic vs triploblastic

A

Diploblastic

  • 2 cell layers
  • cnidarians
  • contain non-living layer, that consist of jelly, instead of mesoderm

Triploblastic

  • three layered
  • most animals
  • has mesoderm
14
Q

2 types of symmetry

A
  • radial symmetry

* bilateral symmetry

15
Q

Radial symmetry

A

• any plane along the main body axis

- cnidarians

16
Q

Bilateral symmetry

A

• a single plane through the anterior-posterior midline

- most animals

17
Q

Protostome

A
  • mouth develops first
  • blastopore becomes the mouth
  • anus forms secondarily
18
Q

Deuterostome

A
  • mouth second

* the anus forms from the blastopore
