Study Set Content:
sporangium bearing leaves are called
sporophylls
In other species, the sporophylls have no chlorophyll, are smaller than the other leaves, and are in terminal conelike clusters called
strobili (singular: strobilus).
Reproduction of Division Lycophyta
meiosis
Division Lycophyta The gametophyte body usually develops in the ground in association with
mycorrhizal fungi
All types produce both antheridia and archegonia on the same gametophyte that, in some species, may live for several years.
Reproduction of Division lycophyta
sperms of Division lycophyta are what that its need water for movement
flagellated
. If the gametophyte is underground, chlorophyll does not develop in the young sporophyte until it emerges into the light.?
yes
bulbs produced in the axils of leaves)
bulbils
Spike Mosses
selaginella
he larger of the two major genera of living club mosses
sporophytes of Selaginella
Their leaves each have a tiny extra appendage, or tongue, called a
ligule
They produce two different kinds of spores and gametophytes—an advanced feature referred to as
heterospory
Quillworts
Isoetes
number of species of quillworts
60
Their leaves (microphylls) are slightly spoon-shaped at the base and look like green porcupine quills, although they are not stiff and rigid. They are arranged in a tight spiral on a stubby stem, which resembles the corm of a gladiola or a crocus.
Isoetes—Quillworts
soetes—Quillworts Reproduction is similar to that of spike mosses, except that no (blank) are formed.
strobili
Like the whisk ferns, club mosses and quillworts are of little economic importance today. ?
