classification

Question 1

Prokaryotes age and abundancy

Answer 1

are the earth’s oldest organisms, and also the most abundant ones.

Question 2

Bacteria

Answer 2

are prokaryotes.

Question 3

prokaryotes metabolic diversity

Answer 3

the most metabolically diverse of all living organisms.

Question 4

two kingdoms under prokaryotes

Answer 4

eubateria and archeabacteria

Question 5

Eubacteria have protection

Answer 5

cell walls made of peptidoglycan, archaebacteria do not.

Question 6

acheabacteria membrane

Answer 6

have plasma membranes c ontain lipids not found in any other living thing.

Question 7

what do genes in eukaryotes and archeabacteria have that eubacteria dont

Answer 7

The genes of both eukaryotes and archaebacteria contain introns, but the genes of eubacteria do not.

Question 8

which kingdom has the extremophiles

Answer 8

archeabacteria-methanogens, halophiles or thermophiles.

Question 9

Origin of Eukaryotes time

Answer 9

1.5 billion years ago

Question 10

endosymbiosis theory

Answer 10

proposes that mitochondria are the descendents of symbiotic, aerobic eubacteria that entered larger cells and then stayed there as symbionts

bas ically, mitochondria and chloroplasts came from: one cell engulfing another bot not digesting it.

Question 11

endosymbiosis proof

Answer 11

M&C own ribosome
M&C can reproduce independent of host
M&C double membrane
M&C have own genetic info

Question 12

which domain has multicellular organisms

Answer 12

True multicellularity only occurs in eukaryotes.

Question 13

who made binomial nomenclature

Answer 13

linneaus

Question 14

Characteristics of archaebacteria

Answer 14

All are unicellular prokaryotes.
Cell walls lack peptinoglycan.
Genes have introns.
Their plasma membranes contain lipids that are not found in any other living things.
They may be either autotrophic or heterotrophic.
They may be the ancestors of eukaryotic cells.
Living archaebacteria are divided into three groups that live in extreme environments: halophiles, thermophiles and acidophiles.

Question 15

Characteristics of eubacteria

Answer 15

All are unicellular prokaryotes.
Cell walls contain peptinoglycan.
Genes lack introns.
All reproduce asexually by binary fission.
They may be either autotrophic or heterotrophic. Some are photosynthetic.
Extremely diversified groups
Certain types may be ancestors of mitochondria and chloroplasts.

Question 16

Characteristics of protists

Answer 16

All are eukaryotic.
Most are unicellular, but some are multicellular.
Protists can be autotrophic, heterotrophic, or both at the same time.
All reproduce asexually, but some can also reproduce sexually.

Question 17

Characteristics of fungi

Answer 17

All are eukaryotic.
Most are multicellular, but some are unicellular.
Cell walls are made of chitin, not cellulose.

Fungi have filamentous bodies called hyphae.
They are all heterotrophs with external digestion of food. They serve as primary decomposers.
Fungi reproduce either sexually or asexually.

Question 18

cell wall of fungi

Answer 18

chitin

Question 19

cell wall of eubacteria

Answer 19

have peptinoglycan

Question 20

cell wall of archeabacteria

Answer 20

lack peptinoglycan

Question 21

Characteristics of plants:

Answer 21

All plants are eukaryotic.
All plants are multicellular.
All plant cells have cell walls made of cellulose.
Most consist of two basic parts: roots and shoots.
Most plants are terrestrial and photosynthetic autotrophs.
Plants have evolved highly specialized structures for reproduction and survival on land.
Plants reproduce sexually, although some can also reproduce asexually.

Question 22

cell wall plantae

Answer 22

cellulose

Question 23

Characteristics of animals

Answer 23

All animals are eukaryotes.
All are multicellular with cells that lack cell walls.
Most reproduce sexually.
All are heterotrophs with internal digestion of food.
Animals have specialized tissues for movement and reaction to stimuli.
Animals inhabit nearly every kind of environment in the biosphere.
