Chapter 30, Problem 5TYKT
Summary Introduction
To examine: Whether the statement “sporangium produces spores, no matter what group it is found” is true or false.
Introduction: Sporangium plays an essential role in asexual reproduction. It is usually found majorly on

___ helps in formation of leaf
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.)

The picture below is of a moss growing on my roof. It shows both the gametophyte and the
sporophyte phases of the life cycle.
Make a sketch and label which part of the moss is the gametophyte and which is the sporophyte.
(Alternatively, you can find a live moss with both phases and take a picture, label it and upload here.)

- 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.
