Cytology
Study of Cells
Cellular Transport
There are two types of cell transport, passive transport and active transport. Passive does not require energy, while active does. Examples of passive are diffusion and osmosis. Examples of active are (endo) and (exo)cytosis.
Interphase
During interphase, the cell grows rapidly to prepare for Mitosis.
Mitosis and Meiosis
Prophase
Spindle Fibers extend to the center.
Metaphase
Nuclear Membrane dissolves and Spindle Fibers attach to the Centromere.
Anaphase
The Chromatids separate while they are pulled apart to opposite ends of the cell.
Telophase
New Nuclear Membranes for around the Chromosomes. This cell has officially divided!
(Meiosis 1) Prophase 1
Centrioles move to opposite ends. Chromosomes form into Tetrads and they trade genetic info. Spindle Fibers reach towards the center.
Metaphase 1
Nuclear Membrane dissolves and the Tetrads line up. The Spindle Fibers attach to the Centromeres.
Anaphase 1
Spindle Fibers pull the Chromosomes to opposite ends of the cell.
Telophase 1
Cytoplasm pinches inward and forms two new cells!
(Meiosis 2) Prophase 2
Centrioles divide and move to opposite ends. Spindle Fibers start to reach towards the center.
Metaphase 2
The Spindle Fibers attach to the Centromeres.
Anaphase 2
The Spindle Fibers pull away all Chromatids to opposite ends of the cells.
Telophase 2
A Nuclear Membrane forms around every Chromatid, forming four new daughter cells.
