During cytokinesis in animal cells, the cytoplasm is divided into two daughter cells by the formation of a cleavage furrow, which forms as a contractile ring of actin microfilaments that pinches the cell membrane.

Cytokinesis is the final stage of the mitotic phase characterized by the physical division and separation of the cytoplasm and other cellular components to produce two separate daughter cells.

Cytokinesis

Microfilaments are dynamic eukaryotic cytoskeletal cables, measuring about 6 nm in diameter, composed of two intertwined strands of actin monomers that polymerize and depolymerize in response to cellular signals.

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.

Cleavage Furrow in Animal Cytokinesis

During cytokinesis in plant cells, the cytoplasm is divided by the development of a cell plate between the two cells.

Cell Plate in Plant Cytokinesis

Actin is a cellular protein that forms monomeric subunits, which assemble into two intertwined strands to create the helical microfilament cables of the cytoskeleton.

Actin

Cytoplasmic streaming is the movement or circulation of cytoplasm within a eukaryotic cell, driven by the actions of actin microfilaments.

Cytoplasmic Streaming

Muscle contraction in animals is a cellular process in which actin filaments are pulled together by motor proteins, such as myosin, to shorten the length of muscle cells.
