Bryophytes Flashcards
Is the division of green plants, refers to embryophytes, and are land plants.
Bryophytes
Sporophyte usually grows from
female gametophyte
types of bryophytes
Mosses, Liverwort, Hornwort
Instead of roots, bryophytes have
Rhizoids
T-F: Bryophytes does not have roots but have crude stems and leaves.
True
Why does the bryophyte’s rhizoid does not absorb nutrients?
Because they are non-vascular.
When mosses releases spores, how does it travel and grow other mosses to other location?
Through water
What happens if there is no water around mosses?
they dry out, but they survive until there will be water again.
What class is mosses under?
Bryopsida
What class is Liverworts under?
Marchantiopsida
What class is Hornworts under?
Anthocerotopsida
How many species are there in moss?
20,000
T-F Some from class Bryopsida are more than 1 meter in height
True
Are aquatic plants with leaf-like structures and form branched clusters.
Hornworts
A blanket of soft spongy moss
Gametophyte stage of the moss life cycle
Are leafy, flowerless, rootless plants.
Liverworts
What does thallus mean?
Body of plant
Capsules are long and look like needles.
Hornwort
Capsules are roundish and black on a translucent stalk
Liverwort
Capsule are roundish, or long and coloured on a green stalk.
Moss
Leaves are spirally arranged around stem, have a nerve or costa, have obvious border of cells different from the rest of the leaf.
Moss
Rhizoids are brown, sometimes white, and branched.
Moss
Rhizoids are white and reddish
Liverwort or hornwort
Leaves in 2-3 rows, dividend at the end, with hair-like projections, leaves on the underside the leaves.
Liverwort
A thread-like chain of cells that forms at the earliest stage of development of the gametophyte in the life cycle of mosses plant.
Protonema
Plural of Protonema
Protonemata
Refers to the presence of a single set of chromosomes in an organism’s cells.
Haploid
Refers to the sexually reproducing- having two sets of chromosomes one from each parent.
Diploid
Produces 2 different kinds of spores (male or female)
Heterosporous
is the male sex organ of a haploid structure that produces male gametes.
Antheridium
What is the plural of Antheridium?
Antheridia
Is the female sex organ, which produces female gametes instantly in cryptograms.
Archegonium
Plural of Archegonium
Archegonia
Is a plant or a plant-like organisms that reproduces by spores, without flowers or seeds.
Cryptograms
Examples to this are algae, lichens, mosses, and ferns.
Cryptograms
Why are bryophytes heterosporous?
because they have two different spores.
In dioecious (“two house”) species, individual plants are
either male or female, producing just one type of sex organ.
In monoecious (“one house”) species, both antheridia and archegonia form on ——————————. Occasionally, the environment determines whether a species is monoecious or dioecious.
the same plant.
Mat-like structure
Protonema
Sporophytes develops 3 structure
Foot, spore capsules, and a stalk
Sac for producing spores.
Sporangium
Global algae
Volvox
Unbranded filaments of cells
Ulothrix
One girdle shaped chloroplast
Ulothrix
Full name ni leeuwenhoek
Antonie Van Leeuwenhoek
