Overview: Mito­sis, also known as equa­tion­al divi­sion, usu­al­ly occurs in diploid cells but can also occur in hap­loid cells of […] [...]

Definition: Meio­sis is a spe­cial­ized cell divi­sion that reduces chro­mo­some num­ber by half, result­ing in the pro­duc­tion of hap­loid daugh­ter […] [...]

Cell Envelope Def­i­n­i­tion: A chem­i­cal­ly com­plex, three-lay­ered struc­ture found in most prokary­ot­ic cells, par­tic­u­lar­ly bac­te­r­i­al cells. Lay­ers: Gly­co­ca­lyx (out­er­most). Cell […] [...]

Prophase I: Longer and more com­plex than prophase of mito­sis. Sub­di­vid­ed into five phas­es based on chro­mo­so­mal behav­ior: Lep­totene, Zygotene, […] [...]

Ribosomes in Prokaryotes Loca­tion: Asso­ci­at­ed with the plas­ma mem­brane of prokary­ot­ic cells. Size and Struc­ture: Approx­i­mate­ly 15 nm by 20 […] [...]

General Characteristics of Eukaryotic Cells: Organ­isms Includ­ed: Pro­tists, plants, ani­mals, and fun­gi are all eukary­otes. Cyto­plasm Com­part­men­tal­iza­tion: Eukary­ot­ic cells have […] [...]

1. Structure of the Cell Membrane: Dis­cov­ery and Stud­ies: The detailed struc­ture of the cell mem­brane was stud­ied using the […] [...]

Def­i­n­i­tion: The cell wall is a non-liv­ing rigid struc­ture form­ing the out­er cov­er­ing of the plas­ma mem­brane in fun­gi and […] [...]
