Flashcards in Chapter 3- Final Exam Study Guide Deck (31)
There are two characteristics about the kingdom Animalia that define the kingdom as different from the others. What are they?
-digest food outside themselves
- cellular respiration
What are the 4 characteristics about the kingdom Animalia that define the kingdom as different from the others. What are they?
- number of tissue layers
- origin of the mouth
-type of body cavity
Compare deuterostomes and protostomes
Deuterostomes (2nd mouth) -
Mouth is formed after the anus during embryonic
Phyla enchodermata (sea stars) & chordata (humans)
Protostomes (1st mouth) -
Mouth forms before the anus
Phyla and mallusca (clams) , orthopedist (flies) and all other animal phyla
Give an example of an organism for each type of symmetry
Asymmetrical- Poriferans (sea sponges)
Radical symmetry- chordates ( ppl) or dragonflies
Diploblasts have which two tissue layers?
1. Ectoderm (outer skin)
2. Endoderm (inner skin)
6. What is the other tissue layer that triploblasts have and diploblasts don’t have?
Mesoderm (middle skin)
7. Be able to tell the difference between a diploblast and a triploblast from a diagram
Look at diagram
8. There are three types of body cavity configurations in triploblasts. Describe each.
Look at pic
Acoelomate (no coelom):
No space in body other than it has layers directly connected
Pseudocoelomate (false coelom):
Mesoderm around one part and endoderm around other part of the space
ex. Hook worms
Have mesoderm surround the entire space in the body
ex. Humans, birds
Be able to recognize the body cavities from diagrams
Give an example of an organism for the different body cavity types
With # 8
What is cellular respiration?
The process of changing food molecules, like glucose, to carbon dioxide and water. The energy released is trapped in the form of ATP for use by all the energy- consuming activities of the cell
What is the chemical formula for cellular respiration?
C6H12O6 + 6O2 -> 6CO2 +6H2O
Glucose and oxygen make carbon dioxide and water
Name the stages of cellular respiration and Include the amount of ATP produced in each stage.
- 2 ATP
2. Pryovic Acid oxidation
- No ATP
3. Citric acid cycle
- 2 ATP
4. Electron transport chain
- 32 ATP
14. Where do the FADH2 and NADH go during cellular respiration?
They travel from the kerb cycle to the ETC and release lots of energy.
Which stage is most energy efficient?
ETC is most efficient
- look up if right and why
How much ATP is produced in the electron transport chain?
17. Compare dioecious and monoecious
Sexes are separate, must meet in order to pro-create
Both male and female reproductive structures in one organism, don’t need to meet to pro-create
18. What does sessile mean?
Sessile: fixes to one spot
ex. Sea sponges, sea enimines
19. Alternation of generations happens in many species of Cnidarians. Look at a diagram of this process. Be able to identify the planula, Medusa, and polyp
Look at diagram
Accumulation of nerve tissue of one end.( a head developes)
What are the three tagmata In Arthropods and what is each generally known for?
Function is for sensory and feeding
Locomotion (wings and legs)
Contains digestive organs
Why is an exoskeleton a good thing?
S- provides support
M- allows for movement
Which two phyla are deuterostomes
1. Phylum Echinodermata
Compare closed and open circulatory systems
Blood doesn’t leave vessels
Blood is pumped through a short aorta into a space, does leave vessels and baths organs in blood
Both have blood and a heart, gas, nutrient and waste exchange
Open is phylum mollusca
Closed is phylum annelida
25. Describe organ level, cellular level, tissue level and organ system level of organizations
Organ system level of organizations:
Organs come together to form system
Ex. Digestive system. Lots of parts come together to break down food
Cellular level of organization
Have loosely organized cells with no well defined tissues
Tissue come together to form an organ
ex. Organs join together to create brain
When cells with similar jobs form tissues ex muscle tissue
Why are calcareous ossicles important in sea stars?
27. What are tube feet good for?
Movement, respiration’s, get food
Within the phylum chordata, there are three subphyla. What are they?
everything with a backbone
Which subphylum from 28 have the most organisms?
