what is an animal lmao?

A

multicellular organisms

44

A

eukaryotic, meaning they contain a membrane-bound necleus

45
Q

motile def

A

meaning animals can ‘move’ or ‘go places’ at some part of their life cycle

46
Q

must eat other organisms (or products of organisms) in order to obtain nutrients

Echinodermata
Chortdata
49
Q

major features of major phyla (phylum):

A

Porifera = perforated interior wall

Cnidaria = stinging cells

Platyhelminthes = flattened shape

Nematoda = round in cross section

Mollusca = muscular foot, shell

Annelida = numerous circular segments

Arthropoda = exoskeletons, jointed limbs

Echinodermata = five-fold radical symmetry

Chordata = dorsal, hollow nerve cord

50
Q

what animals must do to live

A

a) moving
b) finding food
c) ingest food
d) digest food
e) carry the nutrients to all parts of their body
f) obtain oxygen
g) get oxygen to all of their tissues
h) get rid of waste
i) manage water influx, usage and efflux
j) sense and respond to environmental changes

51
Q
  1. radical symmetry
  2. bilateral symmetry
  3. complex symmetry
A
  1. any line going through the center of the animal will show a symmetrical divide
  2. a line going alone the middle of the animal will show a symmetrical divide
  3. symmetrical lines are much more complicated to make, in total, the animal will look asymetrical
