Chapter 28, Problem 28.3CR
Summary Introduction
To hypothesize and explain: The origin of apicomplexan
Introduction: The hypothesis includes the formation and the presence of plastid like organelles inside the sporozoite stage of the species of the plasmodium. They are called as the apicomplexan parasites. The modified plastid is called as the apicoplast. The sporozoites are present inside the gut wall of the mosquito. The parasitic stage sporozoite enters through the salivary glands of the mosquito gets transmitted into the human blood by the bite of a mosquito.

Although they are not photosynthetic, apicomplexan parasites such as Plasmodium have modified plastids. Describe a current hypothesis that explains this observation
Apicomplexans evolved from a photosynthetic ancestor and have the remnant of a chloroplast. This organelle no longer acts in photosynthesis, but remains essential to the protist. Why might targeting this organelle yield an antimalarial drug with minimal side effects in humans?
The termite gut environment is lacking a fresh supply of oxygen O2.
However, it is rich with food due to the presence of bacteria that contain
enzymes capable of breaking down cellulose and lignin, the
macromolecules that make wood. Use this information to determine
which of following protista groups is more likely to be found in a termite
gut.
Diatoms
Radiolaria
Parabasilids
O Rhodophyta
O Foraminifera (Forams)

- 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.
