Seedless vascular plants are
plants that contain vascular tissue, but do not produce flowers or seeds
. In seedless vascular plants, such as ferns and horsetails, the plants reproduce using haploid, unicellular spores instead of seeds.
What are the two characteristics of a seedless vascular plant?
Which two characteristics do seedless vascular plants have that nonvascular plants do not have? They
have phloem and true stems
. They have true roots and use spores to reproduce. They live in moist environments and have xylem.
What are the general characteristics of seedless vascular plants quizlet?
What are some characteristics about Seedless Vascular Plants? Seedless vascular plants include ferns, whisk ferns, club mosses, and horsetails. The plants do not produce seeds so, like bryophytes, they are dispersed (spread) by windblown spores.
The gametophyte and sporophyte are independent
.
What are the characteristics of seedless non vascular plants?
Seedless nonvascular plants are
small, having the gametophyte as the dominant stage of the lifecycle
. Without a vascular system and roots, they absorb water and nutrients on all their exposed surfaces. Collectively known as bryophytes, the three main groups include the liverworts, the hornworts, and the mosses.
What are some characteristics of seedless plants?
Seedless vascular plants include ferns, horsetails and clubmosses. These types of plants
have the same special tissue to move water and food through their stems and foliage
, like other vascular plants, but they don’t produce flowers or seeds. Instead of seeds, seedless vascular plants reproduce with spores.
What are 4 key traits of seedless vascular plants?
Key Points
Seedless vascular plants
reproduce through unicellular, haploid spores instead of seeds
; the lightweight spores allow for easy dispersion in the wind. Seedless vascular plants require water for sperm motility during reproduction and, thus, are often found in moist environments.
What are two types of seedless plants?
The two groups of seedless plants are
nonvascular plants and seedless vascular plants
. Mosses, liverworts, and hornworts do not have vascular tissue to transport water and nutrients.
What are some of the functions of vascular tissue in seedless plants?
The vascular tissues in seedless plants are responsible for
the transport of water, sugar and other organic elements
. Plants that replicate and propagate by spores comprise the seedless vascular plants.
Both bryophtes (the mosses) and seedless vascular plants (mostly ferns) rely on
water fertilization
, do not have complex xylem and phloem, do not have complex gametophytes, and simple root like systems instead of the roots you see in other vascular groups.
What is the size of seedless vascular plants?
Seedless vascular plants went on to dominate the land through the Carboniferous period, about 300 million years ago. At that time, they grew to
heights of 15 meters or more
.
What are the two types of vascular tissues in plants?
INTRODUCTION. The vascular tissues of plants, which are composed of specialized conducting tissues,
xylem and phloem
, form continuous systems through the plant body and provide transport pathways for water, nutrients, and signaling molecules and support a plant body against mechanical stresses.
What is the connection between electricity production and seedless vascular plants?
The connection between electricity production and seedless vascular plants is that
coal formed from ancient seedless plants that were buried in water and mud before they began to decay
. We use burning coal to generate electricity.
Which of the following characterizes the life cycle of a seedless vascular plant?
The life cycle of seedless vascular plants is
an alternation of generations
, where the diploid sporophyte alternates with the haploid gametophyte phase. The diploid sporophyte is the dominant phase of the life cycle, while the gametophyte is an inconspicuous, but still-independent, organism.
What are some characteristics of vascular plants?
Vascular plants are
advanced plants with a transporting function that occurred through xylem and phloem
. The glucose (produced during photosynthesis), gases, water, minerals, and nutrients are circulated throughout the plant. Vascular plants are eukaryotes.
Which of the following is an example of non Vascular seedless plants?
Nonvascular seedless plants, also known as bryophytes, are classified into three phyla:
Mosses
.
Hornworts
.
Liverworts
.
What are seedless vascular plants called?
The seedless vascular plants include
club mosses
, which are the most primitive; whisk ferns, which lost leaves and roots by reductive evolution; and horsetails and ferns. Ferns are the most advanced group of seedless vascular plants.
