Concept explainers
To tell:
Why binary fission generates chains of cocci in some species and cluster of cocci in some other strains.
Introduction:
Prokaryotes widely exist in three different shapes: spherical (cocci), rod (bacilli), and spiral (spirochetes). An example for a spherical-shaped bacterium is Staphylococcus sp. Staphylococcus is a gram-positive cocci structured as grape-like clusters. If viewed under a microscope, these bacteria appear as round and are clustered together.
Explanation of Solution
The prokaryotic cells are arranged in different forms during binary fission. For example, cocci in chains (streptococci) result from the division in one plane and when daughter cells fail to separate. Cocci in irregular or grape-like (staphylococci) arrangement is due to cell division in three planes and daughter cell failing to separate.
The prokaryotic cells exist in different forms (cocci in chain, pairs, and in grape-like structures).

- Describe the four phases of bacterial cell division. Where would horizontal gene transfer occur? Where would sporogenesis occur? If antibiotics generally target cells which are growing and dividing as fast as they can, when would antibiotics be most effective?

- A researcher is studying the cytology of an organism with endopolyploidy. What will she expect to see? A) Most cell types will be diploid, but one cell type will contain extra copies of all the chromosomes. O B) Aneuploid cells will occasionally arise, but will be quickly eradicated. C) Most cell types will be euploid, but some will be aneuploid. D) All cell types will be polyploid, but the number of copies will vary.arrow_forwardUnder the endosymbiotic theory for the origin of the eukaryotic cell. The ancestor of mitochondria and chloroplasts original became part of mutualism with a larger host cell. Which of the following best explains this mutualism? A) The mitochondria and chloroplasts provided specialized reproduction as part of the proto-germ line while the larger host cell provided energy for growth and reproduction. B) The mitochondria and chloroplasts provided gene products that could be used by the larger host cell for improved parasitization. C) The mitochondria and chloroplasts provided molecular energy in return for protection by the larger host cell. D) The mitochondria and chloroplasts produce toxins that the larger cell utilized to defend itself from other cells mutually increasing the defense of all those involved.arrow_forwardWhich of the following is found in binary fission but not in mitosis? a) duplicated chromosomes attach to the plasma membrane b) replicated strands of DNA seperate c) the result produces 2 nuclei d) following the process, a membrane seperates the 2 copies e) replication of DNA begins at an originarrow_forward
