metaphase II anaphase II B Phase C Phase E sister chromatids align at the center of the cell since spindle fibers can attach to either side of their kinetochores two nuclei reform around two sets of reduced chromosomes as the cell divides in half to form two haploid cells the nuclear membrane dissolves as chromosomes condense and spindle fibers form spindle fibers are only able to attach to the outermost sides of homologous chromosomes allowing them to push the tetrads to the center of the cell
Structure and Composition of Cell Membrane
Despite differences in structure and function, all living cells in multicellular organisms are surrounded by a cell membrane. Just like the outer layer of the skin separates the body from its environment similarly, the cell membrane, also known as 'plasma membrane,' separates the inner content from its exterior environment.
Cell Membrane
The cell membrane is known by different names like plasma membrane or cytoplasmic membrane, or biological membrane. The term "cell membrane" was first introduced by C. Nageli and C. Cramer in the year 1855. Later on, in 1931, the term "plasmalemma" for cell membrane was given by J. Plowe. The cell membrane separates the cell's internal environment from the extracellular space. This separation allows the protection of cells from their environment.
Prokaryotes vs Eukaryotes
The cell is defined as the basic structural and functional unit of life. The cell membrane bounds it. It is capable of independent existence.
Match the following to the descriptions provided.
Introduction:- Cell cycle is defined as the series of sequential regulated events that involves cell growth and duplication of genetic material, and finally leads to the division of single parent cell into two daughter cells. Cell division takes place in both prokaryotic as well in eukaryotic cells. Eukaryotic cells can divide by two different processes - mitosis and meiosis. Prokaryotic cells divide by binary fission.
