Plants

Question 1

What is a plant

Answer 1

multicellular, photosynthetic, photo-autotrophic, eukaryote with cell walls

Question 2

What supergroup do plants fit into

Answer 2

Archaeplastida

Question 3

what are land plants, embryophytes, most closely related to

Answer 3

green algae

Question 4

what is evidence for relation of green algae and embryophytes

Answer 4

1) Their cell walls are both made up of a ring of cellulose synthesizing proteins
2) in cellular division they form phragmoplast and a cell plate

Question 5

What are the questions to ask for classifying plants

Answer 5

1) is it vascular
2 )does the plant have seeds
3) how is it fertilized
4) how is it dispersed
5) what is the dominant generation

Question 6

What two systems make up a plants vascular system

Answer 6

1) Xylem- unidirectional water uptake
2) Phloem- multidirectional sugar transport

Question 7

difference between fertilization and dispersal

Answer 7

fertilization is bringing two gametes to form zygote
dispersal is the transport of a zygote away from the parent plant

Question 8

what are the two generation stages of a plant lifecycle

Answer 8

1) gametophyte
2) sporophyte

Question 9

is sporophytes haploid or diploid

Answer 9

diploid

Question 10

is gametophytes haploid or diploid

Answer 10

haploid

Question 11

Are both spores and gametes haploid

Answer 11

yes

Question 12

What are mosses and liverworts an example of

Answer 12

bryophytes

Question 13

how do bryophytes transport water

Answer 13

osmosis, non vascular

Question 14

What is the dominant generation of bryophytes

Answer 14

Gametophyte

Question 15

What is the mode of reproduction and dispersal for bryophytes

Answer 15

reproduction- water
dispersal- wind, water

Question 16

what are ferns an example of

Answer 16

monilophyte

Question 17

is reproduction still dependent on water for monilophytes

Answer 17

yes

Question 18

are bryophytes the only classification that have gametophyte as the dominant generation

Answer 18

Yes

Question 19

what are cone bearing trees like conifer and pine trees an example of

Answer 19

gymnosperms

Question 20

what is the mode of fertilization and dispersal in monilophytes

Answer 20

reproduction- pollen
dispersal- wind

Question 21

what are flowering plants an example of

Answer 21

angiosperms

Question 22

reproduction mode for angiosperms is…..

Answer 22

wind/ animal

Question 23

dispersal of embryo of angiosperms is….

Answer 23

the lot!
water, animal, wind, mechanical

Question 24

which group is considered most successful and why

Answer 24

angiosperms are most successful due to co-evolution with animals

Question 25

why is animal pollination better than wind

Answer 25

animal pollination is targeted, makes sure fertilizes the right plant

Question 26

what is the cost for plants to keep a specific pollinator

Answer 26

making a food, attractive smell/ colour to attract the specific pollinator
