Seedless Plants
what are the two types of vascular tissue
phloem and xylem
In mosses and ferns, the gametophyte generation is
photosynthetic and free living
mosses differ from other bryophytes because their gametophytes
produce structures that look like leaves and stems
unlike bryophytes, lycophytes _______
produce vascular tissue
Describe features of tracheophytes
produce vascular tissue the sporophyte generation is dominant they are found in most terrestrial habitats
gametophyte
the gamete producing phase, produces zygote in which new plant forms
T or F: Bryophytes are non tracheophytes (non vascular)
True
Conspicous, photosynthetic, gameophytes, and the lack of tracheas are feature of
bryophytes
Mosses, liverworts, and hornworts are members of what informal grouping of nonvascular plants?
bryophytes
The closest living descendants of the first land plants are the
bryophytes
The leaves of ferns are called
fronds
Bryophytes are common in what areas
moist areas of the tropics, near stream beds, damp forest floors
seeds are very resistant structures, that can _______ and nourish the young ________
protect, plant
The waxy cuticle and stomata on the above ground parts of the tracheophytes sporophytes function in
reduction of water loss
the three clades of vascular plants are the lycophytes, pterophytes, and _______
seed plants
Ferns, mosses, and seed plant: place in order to the sizes of their gametophyte with group having smallest first
seed plants, ferns, plants
Liverworts reproduce through
sexual and asexual means
Antheridia and archegonia produce which of the following, RESPECTIVELY
sperm and eggs
A common feature of whisk ferns and horsetails is that they both have sperm with ____; for that reason those plants require free water for ___________
sperm, fertilization
Select all statements true about hornworts
their sporophytes have stomata their sporophytes are similar to those in vascular plants their gametophytes are photosynthetic
what is the main evolutionary innovation that helped the tracheophytes to become dominant in many terrestrial habitats
they developed vascular tissue
what is true about whisk fern sporophytes
they lack leaves, they are photosynthetic
Because water availability was a limiting factor for the growth of early terrestrial plant life, such plants likely had the ability to
tolerate desiccation (little water)
what are the functions of roots
transport of water and plant support
characteristics of fern sporophytes
vascular photosynthetic multicellular
the sporophyte of what plant group consists of evenly forking photosynthetic stems that lack roots and leaves?
whisk forks
