Q

How are gametophytes formed in bryophytes

Study These Flashcards
A

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

24
Q

what process creates gametophytes in bryophytes

25
Describe a gametophyte in bryophytes
A mass of green branched one celled thick filaments called protonemata
26
What do bryophyte gametophytes produce?
Flagellated sperm
27
Where are the flagellated sperm produced in gametophytes
In the antheridia and the archegonia
28
Describe the shape and size of bryophytes
They grow low to the ground and at most are only a few cells thick
29
Where do bryophyte sporophytes grow from ?
The grow out of the archegonia they are the smallest and simplest of all extinct plants
30
What is the function of stomata
Small pores that allow gas movement
31
What contains stomata in bryophytes
Horn wart and moss sporophytes
32
What are bryophytes anchored by
Rhizoids
33
Are rhizoids the same as roots ?
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
What do bryophytes depend on for fertilization
Water
35
When the plant is covered is covered with a thin coating of water where do the sperm swim to ?
They swim towards the archegonia
36
After the Sperm swim into the archegonia what happens
They fertilize the eggs
37
Name the 3 phyla of bryophytes
Hepatophyta Anthocerophyta Bryophyta
38
Name an example of hepatophyta and give a characteristic
Liverwort simplest sporophyte and consist of a short stalk
39
Give an example of anthocerophyta and describe characteristic
Hornworts , the sporophytes resemble grass blades and have a waxy cuticle
40
Give an example of the phylum Bryophyta and describe a characteristic
Mosses . They Are most closely related to vascular plants
41
Describe the habitat of most bryophytes
Common and diverse in moist forests and wetlands . Some can inhabit harsh temperatures
42
What is a peat bog
Wet regions dominated by sphagnum or peat moss
43
What are the phyla of seedless vascular plants
Lycophta and pterophyta
44
Seedless vascular plants are dominated by what life stage
Sporophyte
45
Where are gametophytes located on seedless vascular plants
Tiny plants that grow on or below the soil surface
46
How many types of tissue do vascular plants have and what are their names
2, xylem and phloem
47
Name the function of xylem
Xylem conducts most of the water and minerals and includes dead cells called trachieds
48
Describe the function of phloem
Consists of living cells and distributes sugars, amino acids and other organic products
49
What are the function of roots on vascular plants
They are the organs that anchor vascular plants they allow the plant to absorb water and nutrients from the soil
50
What are the function of leaves on vascular plants
They increase the surface area and allow for more photosynthesis
51
What are the 2 varieties of leaves
Microphylls and nacrophylls
52
Define sporophylls
Modified leaves with sporangia
53
Are most seedless plants homosporous or heterosporous
Homosporous , they produce one spore that develops into a bisexual gametophyte
54
What are the 2 phyla of seedless vascular plants
Lycophyta and pterophyta
55
Give 3 examples of lycophyta
Club mosses, spike mosses, quillworts
56
Give 3 examples of pterophyta
Ferns , horsetails, and whisk ferns
