Total questions: 21
Worksheet time: 14mins
Which stage of plants produce haploid spores in spore cases?
gametophyte
sporophyte
If you are out in nature and look down to see moss as a green, low-growing mass, what stage are you viewing?
gametophyte
sporophyte
T/F: Mosses can carry out photosynthesis in the gametophyte stage.
true; it cannot carry out photosynthesis in the sporophyte stage
false; it carries out photosynthesis in the sporophyte stage
What is the tiny structure, found on the tip of the stalk, which stores the spores called?
(a)
While you are examining a moss, you notice tiny, brownish stalks growing up from the plant. What stage are you looking at?
gametophyte
sporophyte
The ______ begins the sporophyte stage and develops into an embryo.
haploid zygote
diploid zygote
mature sporophyte
mature gametophyte
In the sporophyte stage, what does the embryo develop into?
stalk
spore capsule
mature gametophyte
reproductive structures
What occurs in the capsule, producing spores?
meiosis
mitosis
osmosis
none of these
What is produced in the reproductive structures of male and female moss gametophytes?
(a)
Select any option that describes a way in which the sperm meets the egg, in the moss life cycle.
heavy dew
rain
wind
animals
What is it called when the sperm and egg meet?
meiosis
mitosis
fertilization
all of the above
What are the leaves of ferns called?
fronds
rhizomes
sori
prothalluses
T/F: Moss and other nonvascular plants can reproduce both sexually and asexually.
true; moss, liverworts, and hornworts can all reproduce in both ways
false; only moss can reproduce asexually and sexually
Select any option in which a nonvascular plant could reproduce asexually.
A piece of a moss gametophyte plant breaks off and grows into another plant.
Liverworts can form small balls of cells on the surface of the gametophyte plant, which are carried away by water and grow into new plants if they settle into a damp environment.
The spore capsule of a moss breaks open, releasing spores. The spores land on the ground and grow into gametophytes, which produce the sex cells. The sperm and egg meet, by means of water, and produce a zygote (which grows into the sporophyte plant).
The underground stem of a fern is known as a __________.
frond
rhizome
sori
prothallus
T/F: Roots that anchor ferns and absorb water/nutrients grow from the rhizoid.
true; roots grow from the underground stem of a fern
false; roots grow from the rhizome, a rhizoid is a threadlike structure that anchors nonvascular plants to the ground.
What is the structure, that usually grows on the underside of fronds, that produces spores called?
rhizome
prothallus
frond
sorus
What is the gametophyte plant of a fern called?
prothallus
sorus
rhizoid
frond
Select all options which apply to a way in which a fern can reproduce asexually.
Fern rhizomes can grow and form branches, in which fronds and roots develop from. Then, the new rhizome branch can be separated and grow on its own.
Ferns release spores from a capsule, which fall to the ground, and develop into new gametophyte plants. Then, the sperm and egg meet, producing the zygote.
In apogamy, a sporophyte grows into a gametophyte without fertilization occurring. Ferns use this method of reproduction when conditions are too dry to permit fertilization.
T/F: Both the fern sporophyte and gametophyte can carry out photosynthesis.
true; both structures are photosynethic
false; only in the gametophyte stage
What am I describing below?
First, meiosis occurs in the spore case. Then, the spores are ejected and grow into the prothallus (the gametophyte plant). The prothallus produces sex cells that fertilize and produce a zygote, which grows into a spore-producing sporophyte.
(a)
