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
|
Part 2: Using the completed data table, answer the following questions:
- What is common among all samples?
- What is common among organisms from samples 1, 9, and 10?
- What is common between the circulatory system of organisms from samples 5, 6, and 7, but different in organisms from sample 4?
- What is common in the respiration system of organisms from samples 2 and 4?
- What gas is delivered to the respiratory system of organisms from samples 1, 9, and 10? Why?
- Which organisms are producers?
- Which organisms are decomposers?
- Look at the surface of your hand. You will see the skin and hair made up of protein called keratin. Which organisms did humans inherit that protein from?
- Which organisms have blood?
