Summary Introduction

To review:

The comparison of different responses to the light stimuli between partners of wild and mutant type.

Introduction:

The fungus Cryptococcus neoformans is a pathogen found in patients with weakened immune system like HIV/AIDS (Human immunodeficiency virus/Acquired immunodeficiency syndrome) patients. It is a dangerous pathogen that causes cryptococcosis with severe symptoms like encephalitis and pneumonia-like illnesses. It thrives well in dark places, which is suitable for sexual reproduction, whereas light inhibits the sexual reproduction process by affecting the development of dikaryon stage.

After plasmogamy has occurred, many molds (Mucoromycetes) exist in a heterokaryotic stage for up to centuries at a time. What occurs at the immediate end of this stage? The nuclei fuse in a process called karyogamy. The hyphae fuse in a process called karyogamy. Diploid spores are produced in various spore-producing structures. A haploid zygote is formed that becomes multicellular through repeated rounds of mitosis.
In the pictures below, identify the arrowed reproductive structures of microscopic cyanobacteria based on the following descriptions: Akinetes are dormant structures larger than the vegetative cells, are rich in food reserves, and have thick walls.  Most filamentous cyanobacteria develop akinetes in adverse conditions (e.g., winter, dry periods).  When favorable conditions return, they germinate and produce new filaments. Hormogonia are short pieces of filaments consisting of 5–15 trichomes that fragment and develop into new filaments. Heterocytes (or heterocysts) are multicellular structures that have a thick and massive sheath, formed by members of the Nostocales.  It is the location of the enzyme nitrogenase for nitrogen fixation, the conversion of nitrogen gas into ammonium and then amino acids.  They may be intercalary or terminal in position and may germinate from either end or both the ends to give rise to new filaments. Non-filamentous cyanobacteria generally produce spores…
