Assignment: SCIE207 Phase 5 Lab Report

Title: Taxonomy Lab to Show Organism Relationships

Instructions: You will need to fill out the data table and answer a set of questions.

When your lab report is complete, post it in Submitted Assignment files.

Part 1: Using the lab animation, fill in the following data tables to help you answer the questions that follow:

Table 1: Samples 1–5

Phylum/Division	Sample 1: Chrysophyta	Sample 2: Annelida	Sample 3: Arthropoda	Sample 4: Amphibia	Sample 5: Aves
Common Feature
Nutrition How does the organism break down and absorb food?	Autotrophic	Heterotrophic – Earthworms eat their way through dirt, so they are detritivores.	Heterotrophic – Some are vegetarian, some are carnivorous, and some are decomposers.	Heterotrophic – These are usually vegetarian as tadpoles and carnivores as adults.	Heterotrophic
Circulatory System (Transport) How does the organism get what it needs to cells (open, closed, diffusion only)?	Diffusion only	Closed with 5 aortic arches (hearts)	Open circulatory system with a heart pumping hemolymph	Closed with 3-chambered heart	Closed with 4 – chambered heart
Respiratory System How does the organism get oxygen and release carbon dioxide?	Diffusion only	Diffusion through skin	Diffusion through tracheal tubes	Diffusion through gills as a tadpole and through lungs and skin (especially) as adults	Diffusion through the lungs
Reproductive System Does the organism use asexual or sexual reproduction (eggs, seeds, spores, placenta, type of fertilization)?	Asexual	Hermaphrodites: One body has both sexes Sexual: His special organ called clitellum that moves from the front of the worm to the rear and then falls off, containing the eggs	Sexual: Mostly internal fertilization	Sexual: Mostly external fertilization; must be in water or very moist area	Sexual: Eggs; internal
Excretory System How does the organism get rid of wastes and maintain an ionic balance of fluids?	Diffusion	Nephridia in each segment; solid waste. Exits through the anus	Malpighian tubeles	Kidneys, intestines, anus	Kidneys, intestines, anus
Growth and Development Does the organism go through metamorphosis, develop in an egg or uterus, or grow from seeds?	Start as small cells; grow bigger until division	Start out as fertilized eggs, hatch into little worms that continue to grow, and then mature sexually into adults	Complete (egg, larvae, pupae, adult) or incomplete (egg, nymph, adult) metamorphosis	Metamorphosis; Egg, tadpole, adult	Develop in egg
Regulation How does the organism control body processes (hormones, nervous system)?	The nucleus directs protein synthesis. Euglena have eye spots that can detect light	Tiny anterior brain, ganglia, and the nerve cord runs the length of the body	Tiny anterior brain, nerve cord, ganglia, and extremely well-developed sensory organs	Brain, nervous system, good reflexes	Nervous and endocrine systems
Sample organism	Phytoplankton	Earthworm	Fruitfly	Frog	Bird

Table 2: Samples 6–10

Phylum/Division	Sample 6: Reptilians	Sample 7: Mammalia	Sample 8: Bryophyta	Sample 9: Gymnosperm	Sample 10: Angiosperm
Common Feature
Nutrition How does the organism break down and absorb food?	Heterotrophic – Covered with scales	Heterotrophic – Nuture their young with milk	Autotrophic – Nonvascular plants	Autotrophic – Have needles and seeds but no flowers	Autotrophic – Have flowers
Circulatory System (Transport) How does the organism get what it needs to cells (open, closed, diffusion only)?	Closed with 4 – chamber heart	Closed with 4 – chamber heart	Diffusion through cell walls and cell membranes	Xylem and phloem	Xylem and phloem
Respiratory System How does the organism get oxygen and release carbon dioxide?	Diffusion through the lungs	Diffusion through the lungs	Diffusion through cell membranes	Diffusion through stomata	Diffusion through stomata
Reproductive System Does the organism use asexual or sexual reproduction (eggs, seeds, spores, placenta, type of fertilization)?	Sexual: Eggs; internal	Sexual: Placental, in-uterus development (internal)	Sexual: Alternation of generations. Must be in a moist area for the sperm to swim to the egg	Sexual: Alternation of generations. Pollen is the male sex cell	Sexual: Alternation of generations. Pollen is the male sex cell
Sexual: Excretory System How does the organism get rid of wastes and maintain an ionic balance of fluids?	Kidneys, intestines, anus	Kidneys, intestines, anus	None	None	None
Growth and Development Does the organism go through metamorphosis, develop in an egg or uterus, or grow from seeds?	Develop in eggs	Develop in-uterus	Spores, not seeds	Naked seeds in cones	Seeds protected in pods, shells, fruit, and so forth
Regulation How does the organism control body processes (hormones, nervous system)?	Nervous and endocrine systems	Big brain; well-developed nervous system and endocrine system	none	Hormones in apical bud, root, and stem	Hormones in apical bud, root, stem, and leaves
Sample organism	Snake	Cat	Moss	Pine Tree	Rose
