Section 22-3 Flashcards
What is vascular tissue
A type of plant tissue specialized to conduct water and nutrients throughput a plant
What kind of cells did the first vascular plants have that were specializes to conduct water
Tracheids
What is true about tracheids
A. They are hollow cells
B. They are connected end to end
C. Their thick cell walls resist pressure
D. They are the key cells of phloem
A b c
What is the function of xylem
It carries water upward from the roots to every part of a plant
what is the function of phloem?
transports solutions of nutrients and carbohydrates produced by photosynthesis
is the following sentence true or false, phloem and xylem cannot move water and nutrients against the force of gravity
false
what is lignin
a substance that makes the cell walls rigid
roots
underground organs that absorb water and minerals
leaves
photosynthetic organs that contain one or more bundles of vascular tissue
stems
supporting structures that connect roots and leaves, carrying water and nutrients between them
spore bearing vascular plants include what three types of plants
club mosses, horsetails and ferns
is the following sentence true or false, vascular plants have true roots and stems
true
the fossilized remains of ancient forests of club mosses exist today as huge beds of
coal
circle the letter of each structure a horsetail has
A. stems
B. cones
C. leaves
D. roots
a c d
ferns are members of phylum
pterophyta
what are rhizomes
underground stems
the large leaves of ferns are called
fronds
fronds grow from what fern structure
rhizome
in what kind of habitat are ferns most abundant
wet or seasonally wet habitats. they are found in the shadows of forests
what is the dominate stage in the life cycle of ferns and other spore bearing vascular plants
the diploid sporophyte
fern sporophytes produce haploid spores on the underside of their fronds in tiny containers called
sprorangia
what are sori
clusters of sprorangia
are the spores of ferns haploid or diploid
haploid
study photo
where are the antheridia and archegonia found in ferns
on the underside of the gametophyte
why does the fertilazation in ferns require at least a thin film of water
to allow the sperm to swim to eggs
circle the letter of each sentence that is true about the life cycle of ferns
A. the zygote grows into a new gametophyte
B. the sporophyte is a heart shaped, green structure.
C. fern sporophytes often live several years
D. when spores germinate they grow into haploid gametophytes
c and d
