Chapter 22, Problem 3AL
Summary Introduction
Encystment is the formation of the cyst by an organism during unfavorable conditions. Cysts are thick-walled structures that are resistant to desiccation and other harmful conditions. In case of bacteria, the cyst wall is made by added peptidoglycan resulting in thickening of the normal cell wall, whereas in the case of protozoans, it is made up of chitin.

An organism is a mixotroph loses its plastids, it survives because of which reason;
1. It has an endospore and becomes dormant until conditions improve 2. It has photosynthesis by membranes present in the cytoplasm
3. since it is also a heterotroph engulfs organic material by phagocytosis or by absorption for nutrition 4. uses mitochondria that acquite after loosing its plastids

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…arrow_forward
- In the diagram below, identify the structures of a cyanobacterial cell based on the following descriptions: a) Outer cellular covering which includes: Mucilaginous layer – outermost layer covering the cell wall; protects the cell from harmful factors of the environment Cell wall – found just below the mucilaginous layer; 2 or 3-layered, the inner layer lies in between the outer wall layer and plasma membrane; the outer layer is made of peptidoglycan Innermost plasma membrane – selectively permeable membrane enclosing the cytoplasm b) Cytoplasm – found below the plasma membrane; the protoplasm which contains structures of different shapes and functions. Lamellae, which contain pigments such as chlorophylls, carotenes, xanthophylls, phycoerythrin and phycocyanin, are located in the peripheral region of cytoplasm.
