Bryophyte Basics
These types of plants lack tubelike structures to transport water and nutrients.
nonvascular plants
Rootlike structures that anchor a nonvascular seedless plant to a surface
rhizoids
These plants are generally larger because they have tubelike structures to transport water.
vascular plants
This substance is added to potting soil because it can retain large amounts of water
peat moss
Which of these is a vascular seedless plant?
A) Liverwort
B) Moss
C) Fern
D) Hornwort
C) Fern
The collective name many scientists use for all nonvascular seedless plants.
bryophytes
The technical name for the leaves of a fern
fronds
These vascular seedless plants have hollow stems containing silica, making them abrasive.
horsetails
Mosses are often the first plants to grow in these types of areas after a fire or mudslide.
barren areas
Which characteristic is unique to hornworts among bryophytes?
A) They have rhizoids.
B) Each photosynthetic cell has only one chloroplast. C) They reproduce with spores. D) They live in moist environments.
B) Each photosynthetic cell has only one chloroplast.
Nonvascular plants used.............. to reproduce.
Spores
Unlike mosses, these nonvascular plants have a "thallose" form and can have unicellular rhizoids.
liverworts
These vascular seedless plants have roots, stems, and scalelike leaves
club mosses
This mineral, found in sand, is what makes horsetails good for scrubbing pots
silica
Rhizoids in liverworts are always:
A) Multicellular
B) Vascular
C) Unicellular
D) Photosynthetic
C) Unicellular
This material is required for the reproduction of bryophytes
Water
This part of a bryophyte is often only one cell layer thick and lacks a cuticle
photosynthetic tissue
Ancient ancestors of these plants grew as tall as trees and eventually became the fossil fuels we use today.
vascular seedless plants
This group of bryophytes is named after the long, reproductive structures they produce.
hornworts
Which of the following does NOT have roots, stems, or leaves?
A) Club moss
B) Fern
C) Horsetail
D) Moss
D) Moss
Because they lack vascular tissue, materials move from cell to cell through these two processes.
diffusion and osmosis
These are young fern fronds that are sometimes considered a gourmet treat.
fiddleheads
While they look like mosses, club mosses are different because they possess these three structures.
roots, stems, and leaves
This flammable powder, used in early fireworks, comes from the spores of this plant
club moss
What percentage of plant species are vascular plants? A) Over 20%
B) Over 40%
C) Over 90%
D) Exactly 50%
B) Over 40%
