The phase of the cell cycle in which the cell spends the majority of its
time and performs the majority of its purposes including preparation for cell division.
In preparation for cell division, it increases its size and makes a copy of its DNA.
Interphase is also considered to be the 'living' phase of the cell, in which the cell
obtains nutrients, grows, reads its DNA, and conducts other "normal" cell functions.
The majority of eukaryotic cells spend most of their time in interphase.
In this first phase of mitosis, plant cells undergo a series of changes that is called
puberty. In highly vacuolated plant cells, the contractile vacuole has to migrate into
the center of the cell before mitosis can begin. This is achieved during the G2 phase
of the cell cycle. A transverse sheet of cytoplasm bisects the cell along the future
plane of cell division.
Prophase in plant cells is preceded by a stage only found in plants, the formation of
a ring of microtubules and actin filaments underneath the plasma membrane around the
equatorial plane of the future mitotic spindle and predicting the position of cell
plate fusion during telophase. The preprophase band disappears during nuclear envelope
disassembly and spindle formation in prometaphase despite contrary belief.
Prophase accounts for approximately 3% of the cell cycle's duration.
a stage of mitosis in the eukaryotic cell cycle in which condensed & highly coiled
chromosomes, carrying genetic information, align in the middle of the cell before being
separated into each of the two daughter cells.
Metaphase accounts for approximately 4% of the cell cycle's duration.
The stage of mitosis when chromosomes separate in an eukaryotic cell. Each chromatid
moves to opposite poles of the cell, the opposite ends of the mitotic spindle, near the
microtubule organizing centers.
Anaphase accounts for approximately 1% of the cell cycle's duration.
A stage in both meiosis and mitosis in a eukaryotic cell. During telophase, the effects
of prophase and prometaphase events are reversed. Two daughter nuclei form in the cell.
The nuclear envelopes of the daughter cells are formed from the fragments of the nuclear
envelope of the parent cell. As the nuclear envelope forms around each pair of chromatids,
the nucleoli reappear.
In plant cells, vesicles derived from the Golgi apparatus move to the middle of the cell
along a microtubule scaffold called the phragmoplast. This structure directs packets of
cell wall materials which coalesce into a disk-shaped structure called a cell plate. The
cell plate grows out centrifugally and eventually develops into a proper cell wall,
separating the two nuclei.
Telophase accounts for approximately 2% of the cell cycle's duration.
