Question 20

Explain General seedless plant life cycle

Answer 20

Goes through a MULTICELLULAR haploid stage called gametophyte into a MULTICELLULAR diploid stage called sporophyte.

Question 21

Answer 21

Stages.

Question 22

What does the gametophyte stage produce?

Answer 22

Gametes

Question 23

What are the gametes called in a seedless plant lifecycle?

Answer 23

Female archegonia (egg)
Male antheridia (sperm)

Question 24

Answer 24

Both are single celled haploid

Question 25

Answer 25

Diploid single celled

Question 26

What is the sporophyte?

Answer 26

Multi cellular diploid stage

Question 27

Explain the Sporophyte stage

Answer 27

Cells in sporangium undergo meiosis to release spores (single cell haploid)

Question 28

What are four major groups of plants?

Answer 28

Bryophytes
Seedless vascular plants
Gymnosperms
Angiosperms

Question 29

types of Bryophytes (non-vascular)

Answer 29

Mosses, liverworts, hornworts

Question 30

Type of seedless vascular plants

Answer 30

Ferns

Question 31

What are gymnosperms

Answer 31

Plants with seeds on scale like structures called cones

Question 32

What are Angiosperms

Answer 32

Flowering plants

Question 33

What stage is dominant in non vascular plants?

Answer 33

Gametophyte stage

Question 34

Explain asexual reproduction in liverworts:

Answer 34

They contain Gemma cups on the thallus that have gemmae that are washed out of the cups by rain water to spread.

Question 35

How do liverworts produce sexually?

Answer 35

Reproductive structures grow on the thallus. The Antheridiophores contain antheridia that produce sperm and swim to the genial archegoniophore.

They fertilize creating the zygote that developed into the diploid sporophyte.

Question 36

What happens in liverworts after the sporophyte stage?

Answer 36

The sporophyte produces spores that release and grow into the new thallus.

Question 37

What is unique about hornworts?
Hint* energy

Answer 37

They have a photosynthetic sporophyte

Question 38

Explain the prothallium

Answer 38

Heart, Archegonium in the top

Sides, antheridium and the bottom “roots” is the rhizoids

Question 39

Name a type of liverwort

Answer 39

Marchantia

Question 40

What is the visible part of the fern sorus?

Answer 40

The indusium

Question 41

What is the “flowering” part of the horsetail called?

Answer 41

The Strobilus

Question 42

Where do the leaves on a fern plant?

Answer 42

On the stem nodes

Question 43

What does the Strobilus produce?

Answer 43

Spores
