Kingdom- Animalia

Phylum--Chordata

Class- Mammalia

Order-Primates

Family- Hominidae

Genus-Homo

Species-Homo Sapiens

The process of adaption that causes different structures to assume similar forms to perform similar functions.

eg. Wings of a bird vs wings of a bug

When a structure may become highly modified as a population adapts to the new environment.

ex. bird wings and human arms contain the same bones in similar arrangement but perform different functions

What kind of cell is this?

What are the small dark structures?

What surrounds the small dark structure?

Eukaryotic Cell

Nucleus

Cytoplasm

Eat another organism and digest its whole tissues to release nutrients

eg. carnivores

Round with a definite top and bottom

eg. Cnidaria

Kingdom- Animalia

Phylum- Proifera

How to Sponges obtain their food?

Type of symmetry?

They are sessile and obtain food from the water which flows through their pores.

Radial Symmetry

Cnidarians

Cnidaria is what taxon level?

Symmetry?

Phylum

Radial Symmetry

only open at the mouth, digests food by absorbing it through the gastrodermis

can ingest food particles larger than single cells

1- Polyps

2- Medusae

What Phylum do Corals belong in?

What Class?

Who else belongs to this class?

Which body type is dominate?

Cnidarian

Anthozoa

Anemones

Polyps

1-egg

2-zygote

3-planula

4-polyp (Reproductive and feeding polyps)

5-Reproductive polyp produces medusa that creat sprem and eggs

Which Phylum do Jellyfish belong to?

Class?

Dominate body type?

Cnidaria

Scyphozoa

Medusae

1-egg

2-zygote

3-planula

4-Strobila

5-Strobila grow into seperate medusae which create sperm or eggs

Anemones belong to what Phylum?

Class?

Dominating body type?

Cnidarians

Anthozoa

Exclusively as polyps

Bilateral symmetry

three well- developed tissue layers

Cephalized (Having neural and sensory organs in the head)

Why are flatworms so flat?

sounds like a bad joke...

There is no internal fluid to transport materialaround their bodies, so all of the internal tissues must be close to either the epidermis or the gastrodermis.

What is the Phylum and Class of flukes?

How do they live?

Phylum-Platyhelminthese

Class- Trematoda

They are internal parasites so they live in the host of a vertebrate

1-eggs are secreated in the host's feces

2- Snails ingest the egg and become a temporary host for the miracidia in the egg

3- The miracidia frow into cercaria which leave the snail and burrow into a fish

4- The cercaria forms a cyst in the fish which is released when a human eats raw fish.

5- fluke develops into an adult and completes life cycle in human host

What Phylum and Class are tapeworms?

Where do they live?

Phylum-Platyhelminthes

Class-Cestoda

They live in the gut of a vertebrate host

Scolex-has hooks and suckers to act as an anchor

Proglottids-reproductive organs

Anterior- the head end

Posterior-the tail end

Ventral- the belly side

Dorsal-the back side

Ectorderm-the outer layer of an embryo

Endoderm-the inner layer on an embryo

1-ventral nerve cords

2-doral hearts

1-Visceral mass

2-mantle

3-foot

What is the larva of a mollusk?

Is it free-living?
