Animalia

Coelomate, exoskeleton and jointed appendages are characteristics of

• Annelida

• Arthropoda

• Mollusca

• Chordata

Which phylum and species that has these characteristics

Pseudocoelomate narrow body pointed at both ends Locomotion by contraction of longitudinal muscles Dioecious

• Annelida - Pheretima sp

• Nematoda - Achatina sp

• Nematoda - Ascaris sp

• Annelida - Asterias sp

Which phylum is comprised of acoelomate, bilaterally symmetrical and tripoblastic organisms?

• nematoda

• chordata

• porifera

• platyhelminthes

Which phylum and species that has these characteristics

• triploblastic
• acoelomate
• specialized excretion cells called flame cell
• has mouth but no anus
• hermphrodite

• Platyhelminthes - Ascaris sp

• Annelida - Brugia sp

• Platyhelmintes - Taenia sp

• Annelida - Pheretima sp

Which phylum and species that has these characteristics

• bilateral symmetry
• have chaetae/ setae
• have paired of metanephridia
• coelomate

• Annelida - Ascaris sp

• Nematoda - Acatina sp

• Arthropoda - Taenia sp

• Annelida - Pheretima sp

Bilateral Symmetry can be defined as

• 1 line that divides a shape into 2 equal parts
• 1 line that divides a shape into distinct right and left halves that are mirror images
• shape that can be divided into mirror images using any of several lines
• a shape that cannot be divided into mirror images

The difference between diploblastic and triploblastic is

• the number of tissue layers
• the presence of a body cavity
• ability to digest food
• presence of nerve cells

The absence of a body cavity is exhibited by

• Pseudocoelomates
• Acoelomates
• True coeolamates
• Diploblastic organisms

The water-vascular system is responsible for movement in 

• Echinoderms
• Arthropods
• Mollusks
• Nematodes

The visceral mass

• contains all the organs in a mollusk
• is the chitinous layer of an arthropod 
• keeps round worms from being digested
• is responsible for movement in sea stars
