3 DOMAINS OF LIFE
EUKARYA KINGDOMS
PLANT KINGDOM
100
What do characteristics of life help us do?
"Defines" life/the point when something becomes life
100
What 2 categories does a binomial name consist of in the right order?
Genus species
100
What are three domains?
Archaea, Bacteria, and Eukarya
100
What are the four kingdoms?
Plant, animals, fungi, and protist
100
What is the cross-section difference between monocot and dicot/eudicot?
Monocot: vascular bundles scattered all around
Dicot: vascular bundles at the edge
200
How does metabolism contribute to the definition of life?
All living things have the ability to produce energy for growth and maintenance (ex: moving!)
200
What is the use of this taxonomical system?
To organize living and nonliving things, to telling who is related to who, and to name species.
200
Give 2 examples of an organism from any of the three domains
Halophiles, thermophiles, methanogens
Yoghurt, E.coli, Salmonella, Streptococcus
Animals, plants, fungi, protista
200
True or false: animals reproduce mostly sexually.
True, the exception is sea anemones.
200
What is the difference in how seeds are contained in gymnosperms (cones) compared to angiosperms (fruit)?
Gymnosperms: Naked seed in cones
Angiosperms: Seed enclosed in an ovary which becomes a fruit to protect and nourish
300
Give an example of a response to stimulus.
Answer varies.
EXAMPLE: Touching the stove when it is on and jumping back/removing your hand immediately.300
What is the difference between the scientific/specific name compared to the common name?
The scientific name consists of the genus and species of the organism and the common name is just the common name...like bear.
300
True or false? Archaea obtain energy only by feeding off others.
False. Archaea is both autotropic and heterotropic. They break things down in their environment and bring them in.
300
What 2 kingdoms can produce their own food (autotrophs)?
Plantae and Protista
300
What is the role of the vascular tissue?
Transports things around within a plant
Xylem: transports water-soluble nutrients
Phloem: transports sugar, proteins, and other organic molecules
400
What is the characteristic that indicates living systems can maintain an internal environment that is different from the external environment? (HINT AVAILABLE)
Homeostasis
400
Name the 8 taxonomic categories from least broad to most broad.
Species, Genus, Family, Order, Class, Phylum, Kingdom, and Domain
400
What are two differences between Archaea+ Bacteria and Eukarya
Prokaryotic vs Eukaryotic
Entirely asexual vs asexual or sexual
Other answers are considerable
400
State an example of an organism from each kingdom.
ANSWER VARIES- host will tell you.
400
What are 2 differences between spores and seeds?
No nourishment,microscopic, dispersed by wind/water
Nourishment, larger in size and visible, pooped by animals to spread
500
State three characteristics of life that we have learned about in depth over this semester. Define 1.
Mitosis: Growth and Development -> become larger
Meiosis: ability to reproduce
Evolution: adapting populations
500
Given the taxonomic classification, how can you use it to compare which species are more closely related?
Look for the two species that differ in categories as the classification gets more specific.
500
Name and explain one characteristic from Archaea and Bacteria.
Extremophiles, Anaerobic
Peptidoglycan cell ways, decomposers, useful for making some foods
500
Name a special characteristic for 2 kingdoms of the domain Eukarya.
Plants: green coz chlorophyll, provides oxygen
Animals: motile, invertebrates, vertebrates
Fungi: supply essential nutrients to some plants, provides drugs
Protist: form colonies to divide labor of cells
500
Describe the evolution of plants.
Started with charophytes a green algae. Then adapted a cuticle and multicellular structures ensuring it don't dry out...Then pteridophytes as it adapted a vascular tissue helping it grow taller.Then adapted seeds for spreading long distances.
