Platyhelminthes and Nematoda (Lab Practical)

Phylum Platyhelminthes are also known as

flatworms

Phylum Platyhelminthes body plans

acoelomates

Phylum Platyhelminthes are what living

free living or parasitic

Phylum Platyhelminthes have how many germ layers

3, triploblastic

What germ layers do platyhelminthes have

ectodermis, mesodermis, endodermis

the epidermis on Platyhelminthes have

cilia or cuticle

parenchyma (mesoderm)

Platyhelminthes do not have a complete

digestive system

Platyhelminthes have a distinct

excretory system

the excretory system in a Platyhelminthes is known as

protonephridia

the nervous system of a Platyhelminthes looks

ladder like

Platyhelminthes are lacking

respiratory, circulatory, and skeletal systems

Most Platyhelminthes are

monecious

Monecious means

male and female reproductive systems, the organs are in the same individual

Phylum Platyhelminthes classes

Turbellaria, Trematoda, Cestoda

Class Turbellaria Genus

Planaria

ventral

Class Turbellaria has an incomplete

digestive system

Auricle senses

water quality

Class Trematoda aka

the flukes

class Trematoda is an

endoparasite

class Trematoda cuticle covers

the body

Class Trematoda has an

oral sucker that surrounds mouth

Class Cestoda aka

tapeworms

Class Cestoda is an

endoparasite

Class Cestoda body consists of

proglottids and scolex

Proglottids and scolex are

segments

Class Cestoda does not have a

digestive system

What part of the Taenia does not hold eggs

Mature Proglottids

What part of the Taenia holds eggs

Gravid Proglottids

Pseudocoelomate Phyla has

false body cavities

Pseudocoelomate phyla phylums

Nematoda, Rotifera, Nematomorpha

Nematomorpha sexes usually

separate (dioecious)

The Nematomorpha males are

smaller than the female

Nematoda Genus
