Plant Life Cycles

Question 1

Haploidiplonic Life Cycle - Haploid Stage

Answer 1

meiosis creates spores –> spore –> gametophyte –> mitosis creates egg and sperm

Question 2

Haploidiplonic Life Cycle - Diploid Stage

Answer 2

fertilization creates zygote –> embryo –> sporophyte –> sporangia –> spore mother cell

Question 3

In the Haploidiplonic Life Cycle, fertilization creates..

Answer 3

a zygote

Question 4

In the Haploidiplonic Life Cycle, meiosis creates..

Answer 4

spores

Question 5

In the Haploidiplonic Life Cycle, mitosis creates…

Answer 5

egg and sperm

Question 6

What stages are haploid? (Seedless Non-vascular plants/Bryophytes)

Answer 6

mitosis; meiosis transitions to haploid stage

Question 7

What stages are diploid? (Seedless Non-vascular plants/Bryophytes)

Answer 7

mitosis; fertilization transitions from haploid to diploid

Question 8

Where does meiosis occur? (Seedless Non-vascular Plants/Bryophytes)

Answer 8

from sporangium, creates spores

Question 9

Where does fertilization occur? (Seedless Non-vascular Plants/Bryophytes)

Answer 9

females make eggs in archegonia and males make sperm in antheridia (zygote develops in archegonium)

Question 10

Defining Characteristics of Life Cycle (Seedless Non-vascular Plants/Bryophytes)

Answer 10

sporophyte is temporary and grows out of female gametophyte; male gametophyte is dominant (diploid stage)

Question 11

What stages are haploid? (Seedless Vascular Plants)

Answer 11

meiosis, mitosis

Question 12

What stages are diploid? (Seedless Vascular Plants)

Answer 12

mitosis

Question 13

Where does meiosis occur? (Seedless Vascular Plants)

Answer 13

mature sporangium

Question 14

Where does fertilization occur? (Seedless Vascular Plants)

Answer 14

archegonium

Question 15

Defining Characteristics of Life Cycle (Seedless Vascular Plants)

Answer 15

gametophyte prominent (independent of sporophyte); sporophyte dominant in diploid stage; antheridium and archegonium both on gametophyte

Question 16

Where does meiosis occur? (Gymnosperms)

Answer 16

megaspore mother cell

Question 17

Where does fertilization occur? (Gymnosperms)

Answer 17

pollen tube in megaspore

Question 18

Defining Characteristics of Life Cycle (Gymnosperms)

Answer 18

fertilization occurs 15 months after pollination

Question 19

What stages are haploid? (Angiosperms)

Answer 19

mitosis

Question 20

What stages are diploid? (Angiosperms)

Answer 20

mitosis, germination

Question 21

Where does meiosis occur? (Angiosperms)

Answer 21

ovule

Question 22

Which group undergoes double fertilization?

Answer 22

angiosperms

Question 23

In which plant group would you expect to find naked spores and vascular tissues?

Answer 23

ferns

Question 24

In which plant group would you expect to find triple fertilization?

Answer 24

angiosperms

Question 25

In which plant group would you expect to find the gametophyte dominant?

Answer 25

bryophytes

Question 26

In which plant group would you expect to find fertilization happening long after pollination?

Answer 26

gymnosperms
