The ectoplasm is the gel-like outer layer of cytoplasm located directly beneath the plasma membrane in amoeboid protozoans, stabilized by polymerized actin.

Ectoplasm

Pseudopodia are temporary extensions of the cell membrane in amoeboid organisms, produced by the forward flow of fluid, soluble actin filaments.

Pseudopodia

Ciliated protozoans utilize the sweeping motion of their cilia to direct food particles into their mouthparts.

Protozoa are unicellular eukaryotic microorganisms that are nonphotosynthetic and motile. They exist in a wide variety of environments and can be either free-living or parasitic.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.
