What two categories of animals is kingdom animalia divided into

Invertebrates and vertebrates

1

Invertebrates

Animals without backbone, accounts for 95 % of animals

2

Vertebrates

Animals with backbone

3

Invertebrates can be grouped based on their ...

Fossils, body symmetry, patterns of embryo development, ribosomal RNA

4

What's body symmetry

Arrangement of body parts in which parts that lie on opposite sides of an axis are identical

5

What are the types of symmetry

Assymetrical, bilateral, radial

6

Asymmetrical , example

Do not display symmetry , sponges, coral

7

Radial, ex

Parts are arranged in a circle around axis , sea anemone, starfish

8

Bilateral, ex, what do they have

Two similar halves in either side of a central plane, earthworm, exhibit ceohalization, have a dorsal and ventral, have anterior and posterior

9

Exhibit cephalization

Concentration of senses and nerves in the head (ganglia-simple brain)

10

Dorsal and ventral

Back, front

11

Anterior and posterior

Head, tail

12

Germ layers

Tissue layer in embryo

13

What germ layers do most animals have, except for what animal, what animals have two layers

Ectoderm, mesoderm, endoderm , sponges, cnidarians and ctenophores

14

Cnidarians and ctenophores have no...

Middle layer

15

What develops from germ layers

Organs and tissues

16

Acoelomates, ex

Do not have body cavity, interior of the animal is solid, flatworms

17

Pseudocoelomates, ex

Have a false body cavity, roundworms and rotifers

18

Coelomates, ex

Have a true body cavity lined with mesoderm, mollusks, annelids, arthopods, echinoderms, chordates

19

Cleavage

Development of the mouth

20

Pro means, stoma means, first opening called the..., develops into the ...., and second opening develops into..., ex

First, mouth, blastopore, mouth, anus, mollusks, arthopods, annelids

21

Deutero means , stoma means, blastopore becomes , second opening becomes, ex

Second, mouth, anus, mouth , echinoderms, chordates (humans part of this)

22

Invertebrates in order from simplest to most complex

Porifera, Cnidaria and Ctenophora. Platyhelminthes, rotifera, molluska, Annelida, Nematoda, arthopoda, echinoderms , Chordata

23

Common Porifera name

Sponges

24

Characteristics of Porifera

Aquatic,
5000 species, 150 freshwater
No true tissues or organs
Asymetrical,
Sessile as adults (don't move), free swimming larvae
Asexual reproduction by budding or sexual reproduction (most are hermaphrodites producing both egg and sperm)

25

Examples of cnidarians

Hydra, jellies, sea anemones, corals

26

Example of Ctenophora

Comb jellies

27

What two firms can Cnidaria and ctenophores be in

Polyp ( attached to surface), medusa( free floating)

28

What are characteristics of Cnidaria and ctenophores

Simple nerve nets, no ganglia
Radial symmetry
Gut (digestive tract) with single opening

29

List each phylum discussed and animals in each group

Porifera-sponges
Cnidaria- hydra, jellies, sea anemones, corals
Ctenophora- comb jellies
Platyhelminthes - flatworms (Turbellaria-planarians, Trematoda-flukes, Cestoda-tapeworms)
Rotifera -rotifers
Molluska- mollusks (Gastropoda- snails, land slugs, abalones, nudibranchs (sea slugs), bivalvia-mussels, clams, oysters, scallops, cephalopoda- octopi, squid, cuttlefish, nautilus)
