Answer 1

domain Archae

Question 2

What do most bacteria use for locomotion? What is their main mode of reproduction?

What is the means of locomotion employed by the organisms in the phyla zooflagellates

Answer 4

flagella

Question 5

What is the means of locomotion employed by the organisms in the phyla sarcodina

Answer 5

pseudopods

Question 6

In vascular plants what are the two kinds of structures for the transport of water and nutrients?

Answer 6

xylem and phloem

Question 7

a plant that produces flowers

Answer 7

belongs to angiosperms and is vascular

Question 8

Explain how conjugation can significantly affect the growth of a population of bacteria, evn though conjugation does not result in offspring.

Answer 8

If the trait that is passed by the plasmid allows bacteria to survive when they otherwise would not, it will increase population.

Question 9

Name the malady caused by ergot of rye

Answer 9

death

Question 10

Name the difference between monocots and dicots in cotyledons.

Answer 10

monocots have one; dicots have two

Question 11

A virus is not alive because it

Answer 11

cannot reproduce on its own

Question 12

Name the malady caused by candida

Answer 12

thrush

Question 13

What is the female reproductive organ of a flower?

Answer 13

carpel

Question 14

Name the difference between monocots and dicots in the root system

Answer 14

fibrous in monocots and taproot in dicots

Question 15

Name the difference between monocots and dicots in leaf veins.

Answer 15

they run parallel to midrib in monocots and branch from midrib in dicots

Question 16

Name a form of mutualism in which fungi participate. Describe the relationship and job of each participant.

Answer 16

A lichen is a mutualistic relationship between a fungus and an alga. The alga produces food for both creatures via photosynthesis, and the fungus supports and protects the alga. Mycorrhizae are mutualistic relationships between a fungus’s mycelium and a plant’s root system. The mycelium takes nutrients from the root, while it collects minerals from the soil and gives it to the root.

Question 17

Name pathogenic organisms from kingdom Protista

Answer 17

entamoeba histolytica, trypanosoma, balantidium coli, plasmodium, and toxoplasma

Question 18

Why are bryophytes relatively small?

Answer 18

the plant must stay small because bryophytes have no vascular tissue

Question 19

What is the dominant generation in the fern life cycle?

Answer 19

sporophyte generation

Question 20

Name the malady caused by ophiostoma ulmi

Answer 20

dutch elm disease

Question 21

What is the male reproductive organ of a flower?

Answer 21

stamen

Question 22

How is a mushroom like an iceburg?

Answer 22

Typically we only see the fruiting body of a mushroom. Like an iceberg, that visible part is only a small fraction of the total mushroom, because the mycelium is the largest component of a mushroom

Question 23

What type of tree has an abscission layer?

Answer 23

deciduous

Question 24

Name the difference between monocots and dicots in flower parts

Answer 24

multiples of 3 in monocots; multiples of 4 or 5 in dicots

Question 25

What type of life cycle do plants exhibit?

Answer 25

alternation of generations

Question 26

What function do cotyledons perform before germination?

Answer 26

feed the embryo

Question 27

An organism is a multicellular decomposer made of eukaryotic cells. To what domain and kingdom does it belong?

Answer 27

domain Eukarya and kingdom Fungi

Question 28

Name the malady caused by rusts

Answer 28

crop damage

Question 29

What is the means of locomotion employed by the organisms in the phyla ciliophora

Answer 29

cilia

Question 30

What is the purpose of a fruit?

Answer 30

allows for dispersal of seeds away from the parent

Question 31

What phylum contains fungi that do not have a known mode of sexual reproduction?

Answer 31

deuteromycota

Question 32

Why is the bottom of a leaf typically a lighter shade of green than the top of the leaf?

Answer 32

the spongy mesophyll is typically on the underside of the leaf, and it is usually a lighter shade of green

Question 33

Briefly describe conjugation in bacteria.

Answer 33

passes a trait from one bacterium to another via a small strand of DNA called a plasmid

Question 34

What are the technical names of the three common bacterial shapes?

Answer 34

coccus, bacillus, spirillum

Question 35

Meristematic tissue is made of undifferentiated cells. This means that the cells are relatively new, so

that portion of the plant is still growing

Question 36

Name the difference between monocots and dicots in vascular bundles
