23
Q

How are gametophytes formed in bryophytes

A

Bryophyte spores germinate in favorable environments and grow into gametophytes though mitosis

24
Q

what process creates gametophytes in bryophytes

A

Mitosis

25
Q

Describe a gametophyte in bryophytes

A

A mass of green branched one celled thick filaments called protonemata

26
Q

What do bryophyte gametophytes produce?

A

Flagellated sperm

27
Q

Where are the flagellated sperm produced in gametophytes

A

In the antheridia and the archegonia

28
Q

Describe the shape and size of bryophytes

A

They grow low to the ground and at most are only a few cells thick

29
Q

Where do bryophyte sporophytes grow from ?

A

The grow out of the archegonia they are the smallest and simplest of all extinct plants

30
Q

What is the function of stomata

A

Small pores that allow gas movement

31
Q

What contains stomata in bryophytes

A

Horn wart and moss sporophytes

32
Q

What are bryophytes anchored by

A

Rhizoids

33
Q

Are rhizoids the same as roots ?

A

No!!! They are composed of tissues and they lack specialized conducting cells . They do not play a large role in water and mineral absorption

34
Q

What do bryophytes depend on for fertilization

A

Water

35
Q

When the plant is covered is covered with a thin coating of water where do the sperm swim to ?

A

They swim towards the archegonia

36
Q

After the Sperm swim into the archegonia what happens

A

They fertilize the eggs

37
Q

Name the 3 phyla of bryophytes

A

Hepatophyta
Anthocerophyta
Bryophyta

38
Q

Name an example of hepatophyta and give a characteristic

A

Liverwort simplest sporophyte and consist of a short stalk

39
Q

Give an example of anthocerophyta and describe characteristic

A

Hornworts , the sporophytes resemble grass blades and have a waxy cuticle

40
Q

Give an example of the phylum Bryophyta and describe a characteristic

A

Mosses . They Are most closely related to vascular plants

41
Q

Describe the habitat of most bryophytes

A

Common and diverse in moist forests and wetlands . Some can inhabit harsh temperatures

42
Q

What is a peat bog

A

Wet regions dominated by sphagnum or peat moss

43
Q

What are the phyla of seedless vascular plants

A

Lycophta and pterophyta

44
Q

Seedless vascular plants are dominated by what life stage

A

Sporophyte

45
Q

Where are gametophytes located on seedless vascular plants

A

Tiny plants that grow on or below the soil surface

46
Q

How many types of tissue do vascular plants have and what are their names

A

2, xylem and phloem

47
Q

Name the function of xylem

A

Xylem conducts most of the water and minerals and includes dead cells called trachieds

48
Q

Describe the function of phloem

A

Consists of living cells and distributes sugars, amino acids and other organic products

49
Q

What are the function of roots on vascular plants

A

They are the organs that anchor vascular plants they allow the plant to absorb water and nutrients from the soil

50
Q

What are the function of leaves on vascular plants

A

They increase the surface area and allow for more photosynthesis

51
Q

What are the 2 varieties of leaves

A

Microphylls and nacrophylls

52
Q

Define sporophylls

A

Modified leaves with sporangia

53
Q

Are most seedless plants homosporous or heterosporous

A

Homosporous , they produce one spore that develops into a bisexual gametophyte

54
Q

What are the 2 phyla of seedless vascular plants

A

Lycophyta and pterophyta

55
Q

Give 3 examples of lycophyta

A

Club mosses, spike mosses, quillworts

56
Q

Give 3 examples of pterophyta

A

Ferns , horsetails, and whisk ferns
