Flashcards in Unit 3 - Diversity Of Life Unit Deck (31):
Characteristics of prokaryotes:
•No true _______ or _______ ______
•________, circular chromosomes of DNA
•Chlorophyll, if present, _____ in chloroplasts
•cell wall, if present, containing ______ or other substances
•No _______ in flagella of most forms
•nucleus, nucleic membrane
Bacterial cells have 3 shapes. List and describe these shapes.
Bacilli- rod shaped
Cocci - spherical
Spirilla - spiral shaped
List 4 characteristics of algal protists.
Mainly unicellular producers
Chlorophyll and other pigments are located in chloroplasts
Classified into phyla on the basis of color and structure
List 5 characteristics of protozoan protists.
Unicellular, animal like organisms
Most can move and are classified into phyla based on how they move
Heterotrophs and may have special features for obtaining food
Some actively trap food while others are parasites
Undergo both sexual and asexual reproduction
List 5 characteristics of slime mold protists.
Unique life cycle with features of Protozoa and fungi
Some stages are unicellular and others are multicellular
In some species the life cycle begins as a plasmodium
A slime mold plasmodium very slowly oozes along the forest floor
The plasmodium takes in organic matter by phagocytosis
List 5 characteristics of Kingdom Fungi.
Plant like in that many are stationary
Heterotrophic - lack chlorophyll
Since they cannot move to capture food the become parasites or saprophytes
Most true fungi have filamentous stalks called hyphae
Are classified on the basis of spore producing structures
List the 4 different types of fungi.
Land plants are classified into 2 major phyla. List them.
Bryophytes and tracheophytes
Define vascular tissue.
Transport food, water, and minerals throughout plant
What is phylum tracheophyta's common name and habitat?
Moist areas on land
Define innate behavior.
Inherited behavior which in under direct genetic control
List and describe 3 of the 5 examples of innate behavior.
Reflexes- determined by the fixed pathways of the nervous system
Instinct- an innate behavior involving a set of complicated responses
Biological clocks- control animal activities related to time, may be "set" according to environmental stimuli
Define learned behavior.
Behavior that can be changed.
List define and describe 3 of the 5 examples of learned behavior.
Trial and error - a simple form of learning in which motivation, reward, and punishment are important aspects - an earthworms in a T maze will learn to enter the dark moist chamber with a reward of food to avoid the electrodes
Type II Conditioning - the animal learns a voluntary response to achieve the desired effect (reward) - by rewarding your dog after doing a trick, the likelihood of your dog repeating the trick is increased by rewarding it
Imprinting - form of learning related to instinctive behavior - young birds normally imprint on their mother
List and describe the 2 types of social behaviors.
Social hierarchies- is composed of levels of authority- once established the order in society is increased
Territoriality- involves the occupation and defense of definite areas - often enable a male to attract a mate (dominant male)
List the 2 major groups of bacteria within the kingdom Monera.
Archaebacteria and eubacteria
Define binomial nomenclature.
A two term naming system used for classifying organisms
Describe Aristotle's early classification system.
Divided organisms into two groups -plants and animals
Based plants on structure - herbs, shrubs, trees
Based animals on habitat - air, land, sea
In binomial nomenclature, what are 3 points about the genus.
In binomial nomenclature, what are 3 points about the species?
List the five kingdoms.
Fill in this eukaryote table:
•True nucleus and nuclear membrane
•______, _______ chromosomes of DNA and protein
•Chlorophyll, if present, in chloroplasts
•Cell wall, if present, made of different substances
•________ in flagella of all forms
List 2 of the 4 roles bacteria plays in human economy.
Used in the dairy industry
Used to convert alcohol to vinegar
Today's antibiotics are produced by bacteria
Break down material holding together cellulose fibers in plants
List the three main groups of kingdom Protista.
List 2 of the 3 major features of Bryophytes.
Lack of specialized tissues for transport of materials
Lack of true roots stems and leaves
List 2 of the 3 major features of tracheophytes
Have vascular tissue
Have true roots stems and leaves
Not restricted to moist habitats
List 3 of the 5 major features of modern Arthropods
•segmented body covered by an exoskeleton
•pairs of jointed appendages
•well organized muscles with definite points of attachment to the exoskeleton
•body segments in most forms fused into distinct body regions - head, thorax, abdomen
What kind of fertilization do jawless fish have?
Is a Chondrichthyes an endotherm or ectotherm?
Fertilization for 1. Chondrichthyes, 2. Osteichthyes, 3. Amphibians, 4. Reptiles, 5. Aves, 6. Mammalia
