Chapter 23, Problem 4CT
A giant puffball (FIGURE 23.13C) produces trillions of spores that disperse on wind. A stinkhom (FIGURE 23.13D) makes fewer spores and they are dispersed by insects. How are these differences analgous to differences in pollen production and dispersal among plants?

sporangiophores are interpreted as modified branches and consist of a stalk and a shield-
like portion.
Inside of the sporangium, look for the spores each with a pair of elongated appendages
called elaters. These elaters respond to changes in the humidity to aid in spore dispersal.
18. Label the spores on Figure 6 below.
Figure 6. Equisetum strobilius l.s.
Equisetum is homosporous and produces green, free-living, bisexual gametophytes. (See
text Figure 17-40 and 17-41, page 425-427.)

True or false
The fungal component of a lichen thallus is most often a basidiomycete.
In eucarpic thallus, the entire thallus is composed mainly of sporangia.
The tree fern, Cyathea is a eusporangiate fern.
The trophophyll vegetative frond has the same morphology and function as the sporophyll frond.
Tricolpate pollen morphology is a synapomorphy in all dicots.
Hyphal tissue comprise the medulla layer of a lichen thallus.
The Phylum Ascomycota is a monophyletic group.
Homosporous condition in the sporophyte gives rise to bisexual gametophyte.
The Phylum Basidiomycota is a paraphyletic group.
In polycentric thalli, a single zoospore will give rise to several rhizoids.
Heterothallic mycelia require two different, but compatible, mycelia to reproduce sexually.
Having a single cotyledon is a synapomorphy shared by all monocots.
The xylem vessel is considered an apomorphic feature in the monocots and eudicots.
The nuclear fusion of the dikaryotic hyphae is termed as plasmogamy.

The fruiting body of the Basidiomycota (club fungi) is the;
The mushroom (Basidiocarp)
The true morels (ascocarp)
The hyphae
