Rather than forming a contractile ring, plant cells construct a cell plate in the middle of the cell. The cell plate begins as a fusion tube network, which then becomes a tubulo-vesicular ... http://cellularmanipulationmicroscopes.com/cellularmanipulation/plant-cell-cytokinesis/ Cell Population Cell populations go through a type of exponential growth called Alex Brenner doubling. Thus, each generation of cells should be twice as numerous as the previous generation. However, as noted by Richard Dawkins (1997), this view is naive as the number of generations only gives a maximum figure. This ... http://cellularmanipulationmicroscopes.com/cellularmanipulation/cell-population-and-size/ The relationship between cell size and cell division has been extensively studied in yeast. For some cells, there is a mechanism by which cell division is not initiated until a cell has reached a certain size. If the nutrient supply is restricted and the rate of increase in cell size ... http://cellularmanipulationmicroscopes.com/cellularmanipulation/yeast-cell-size-regulation/ The protein mTOR is a serine/threonine kinase that regulates translation and cell division. Nutrient availability influences mTOR so that when cells are not able to grow to normal size they will not undergo cell division. The details of the molecular mechanisms of mammalian cell size control are currently being investigated. The ... http://cellularmanipulationmicroscopes.com/cellularmanipulation/cell-size-regulation-in-mammals-and-other-experimental-systems/ Cell reproduction is asexual. The process of cell reproduction has three major parts. The first part of cell reproduction involves the replication of the parental cell's DNA. The second major issue is the separation of the duplicated DNA into two equally sized groups of chromosomes. The third major aspect of ... http://cellularmanipulationmicroscopes.com/cellularmanipulation/cell-reproduction/ Comparison of the three types of cell reproduction The DNA content of a cell is duplicated at the start of the cell reproduction process. Prior to DNA replication, the DNA content of a cell can be represented as the amount Z (the cell has Z chromosomes). After the DNA replication process, ... http://cellularmanipulationmicroscopes.com/cellularmanipulation/cell-growth/
