Flashcards in Unit 3 - Diversity Of Life Unit Deck (31):
1

Characteristics of prokaryotes:
•No true _______ or _______ ______
•________, circular chromosomes of DNA
•_____ organelles
•Chlorophyll, if present, _____ in chloroplasts
•cell wall, if present, containing ______ or other substances
•No _______ in flagella of most forms

•nucleus, nucleic membrane
•single
•small
•no
•murein
•micro tubules

2

Bacterial cells have 3 shapes. List and describe these shapes.

Bacilli- rod shaped
Cocci - spherical
Spirilla - spiral shaped

3

List 4 characteristics of algal protists.

Mainly unicellular producers
Chlorophyll and other pigments are located in chloroplasts
Mostly aquatic
Classified into phyla on the basis of color and structure

4

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

5

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

6

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

7

List the 4 different types of fungi.

Sporangium fungi
Club fungi
Sac fungi
Lichens

8

Land plants are classified into 2 major phyla. List them.

Bryophytes and tracheophytes

9

Define vascular tissue.

Transport food, water, and minerals throughout plant

10

What is phylum tracheophyta's common name and habitat?

Club mosses/horsetails
Moist areas on land

11

Define innate behavior.

Inherited behavior which in under direct genetic control

12

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

13

Define learned behavior.

Behavior that can be changed.

14

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

15

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)

16

List the 2 major groups of bacteria within the kingdom Monera.

Archaebacteria and eubacteria

17

Define binomial nomenclature.

A two term naming system used for classifying organisms

18

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

19

In binomial nomenclature, what are 3 points about the genus.

First word
Capitalized
Noun

20

In binomial nomenclature, what are 3 points about the species?

Second word
Not capitalized
Adjective

21

List the five kingdoms.

Animalea
Plantae
Monera
Fungi
Protista

22

Fill in this eukaryote table:
•True nucleus and nuclear membrane
•______, _______ chromosomes of DNA and protein
•Have organelles
•Chlorophyll, if present, in chloroplasts
•Cell wall, if present, made of different substances
•________ in flagella of all forms

Several, linear
Micro tubules

23

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

24

List the three main groups of kingdom Protista.

Slime molds
Algal protists
Protozoa protists

25

List 2 of the 3 major features of Bryophytes.

Small size
Lack of specialized tissues for transport of materials
Lack of true roots stems and leaves

26

List 2 of the 3 major features of tracheophytes

Have vascular tissue
Have true roots stems and leaves
Not restricted to moist habitats

27

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
•specialized mouthparts
