Q

Porifera

A

Pore filers organism for water that leaves cavities

Water flows through by choanocytes that are flagellated and woo their flagella that draws water in through pores and out through exit. They filter the water for food

Phagocytosis occurs by choanocytes and then transport particles to a different cell ameovpcyte

A

Include jelly fish
Sea anenamoes
Have stinging cells that paralyze the creatures they are feeding on.

They have symmetry

They have radial symmetry

Q

Triploblasts

Study These Flashcards
A

Include ectoderm and endoderm but also mesoderm

23
Q

Body cavity

Study These Flashcards
A

Is another way to classify animals

24
Q

Coelomates Aceolomates

Study These Flashcards
A

Animals with true body cavity

Acoelomates don’t have it

25
What does a body cavity allow for
The moving around of tissues without rubbing on each other. It’s a fluid filled space that reduces friction. Within body we have serous membrane like our pericardia that doesn’t allow beat of heart to rub against lung
26
Metezoa means
Animals They are enterchangable
27
Eumetazoa
Every animals except sponges or porifera
28
Bilaterians
Humans are apart of this bilateraly symmetrical animals Subgroup within eumetozoa
29
Deuterostomia
Stoma means mouth so all bilaterians are this. This means mouth developed second so anus first The other is protistoms which means mouth first Humans are apart of this This leads to phylum leval of chordates for humans
30
Chordates have hallmarks of what structure
They are names for a notochord Kinda stiff but flexible rod allowed for muscles to pull on notochord to slow for efficient swimming Dorsal hollow nerve chord Nervous tissie that develops on the develops into spinal chord All have post anus tail Ferengial slits
31
Chordates that are not vertavrates
lancelets look almost u change from ancestor Tunicates or sea squirt
32
More specifically than chordates we are what
Vertebrates with vertable column
33
The separations of vertebrates is
Jaws mineralized skeleton
34
Gnath
Jaw or Agnatha no true jaw
35
Gnathestoms
Means jawed fishes Humans are this
36
Pter
Means winged
37
Actinistoa
Lobbed liked muscular fins. Compared to the spiny actinopterygii humans are this
38
Tetrapods
Four appendages which have digits Humans are this Animals lineages that invaded the land Humans specifically in this are mammals
39
Two major types of tetrapods
Amphibians
40
Arthropods
Animal phylum that is most successful with the most adaptive radiation. Means jointed legs Led to insects which are most animals alive today found almost everywhere where organisms are found except for the ocean.
41
Insects wings are derived form
Not the legs. They keep their legs which make them so advantageous
42
Amniotes include only
Reptiles and mammals not amphibians Includes humans
43
Amphibians live
Part of their life on land and part of their life on water Leg eggs that are soft shelled that need to be layed in water
44
Cleodoic
Hard shelled egg. Frees up for dependence of water and allows for oxygen and carbon dioxide to go through
45
Amniotes have 4 extre embryonic membranes
Amnion -Around the embryo and reduces shock Allantois - waste dump Yoke sack- food supply Chorian- got gas exchange like lungs
46
3 major groups of mammals
Monetremes Marsupials Eutherians Mammy have mamery glands that’s produce milk for young
47
Monetremes don’t have
Nipples Milk just oozes out of skin They also leg hard shell eggs Lower body temp and metabolism
48
Marsupials
Immature blob of tissue gets born through vagina and then is somehow able to know to crawl up to the pouch and leach to nipple and developes more and almost is born again
49
Eutherians
Uterus development and undergo a lot Almost ready to be on there own
50
Primates
Eutherians with manipulitable fingers and toes
51
Apes
Doesn’t include monkeys This includes humans
52
Homo
Genus within apes Chimpanzees have different genus it closest living relative
53
Sapiens
Our species name For humans Apps that wear cloths
54
Convolution
An example is when a moths probascis that is able to go up long tube like part of flower for nectar. Specialized for a species organisms that are evolving together to leave out other organisms
