The things you should know for your comparative chart Flashcards
Protista
Nervous - NA
Integument - plasma/cell membra
Respiratory- cellular diffusion
digestive - auto and heterotroph, intracellular
muscle/locomotion - cillia, flagella, psuedopodia
circulatory - cytoplasm and contractile vacuole
osmoregulation - cellular diffusion
excretion - cellular diffusion
skeletal/form - hydrostatic /caco3
porifera
Nervous - N/A
Integument - pinaocytes
Respiratory - diffusion cellular or body wall
digestive - intracellular and choanocytes
muscle/locomotion - sessile but create currents with cilia
circulatory - amoebocytes
osmoregulation -
excretion - diffusion, cellular and body wall
skeletal/form - hydrostatic, CaCO3, SI, Spongin
cnidaria
Nervous - Nerve Net
Integument - Epidermis
Respiratory - gastrovascular/pharynx
digestive - GVC
muscle/locomotion - cessile or freefloating
circulatory - GVC / Diffusion
osmoregulation - diffusion cell and body wall
excretion - GVC
skeletal/form - Hydrostatic Skeleton
platyhelminthes
Nervous - sensory, motor, and association neurons, brain tactile and light reception ocelli
Integument - epidermis with columnar, ciliated cells and adhesive glands
Respiratory - diffusion through body walls
digestive - mouth, pharynx, intestine : extra and intracellular digestion
muscle/locomotion - longitudinal, circular and oblique muscles used for locomotions
circulatory - diffusion across body wall
osmoregulation -flame cells/protonephridia
excretion - diffusion through bodywall
skeletal/form
mollusca
Nervous - sensory organs for sight, same as platyhelminthes
Integument - epidermis (ectoderm) ciliated, mucous gland, chromatophores
Respiratory - diffusion across integument system and gills
digestive - complete disgestive system
muscle/locomotion - “foot” for locomotion and attachment
circulatory - open circulatory that bathes organs directly in hemolymph
osmoregulation -nepgridia
excretion - nephridia
skeletal/form - CaCO3 shell + hydrostatic +mantle
annelida
Nervous - same as mollusca
Integument - cuticle and epidermis with clitellum for mucus
Respiratory - gases diffuse across body wall
digestive - crop and gizzard
muscle/locomotion - longitudinal, circular, oblique muscles
circulatory - closed circulatory system with muscular blood vessels and amebocytes in plasma
osmoregulation - nephridiphore
excretion - nephridophore
skeletal/form - hydrostatic / worm
arthropoda
Nervous - Same as Annelids but add all sense, social behavior and special sense organs in antenna
Integument - chitinous exoskeleton with epicuticle and procuticle
Respiratory - book lungs, gills, trachea
digestive - complete
muscle/locomotion - all 3 muscles, segments works with hydrostatic for movement
circulatory - open
osmoregulation - coxal and malpighian tubes
excretion - coxal and malpighian tubes
skeletal/form - exoskeleton
