A cell's division time is $1$ minute. In $20$ minutes, a culture tube (culture medium) is $1/8^{th}$ filled with cells. When the tube will be fully filled?

In $20$ mins, culture tube is $1 /8^{th}$ filled with cells. Each cell divides every minute producing two daughter cells. Hence, in $21$ min $ = \frac{1}{8} \times 2 = \frac{1}{4}$ In $22$ min $\frac{1}{4} \times = \frac{1}{2}$ In $23$ min $\frac {1}{2} \times 2 = 1$ That means, in $23$ minutes, the culture tube will be completely filled.

A cell's division time is $1$ minute. In $20$ minu

Cell Cycle and Cell Division

Cell Cycle:

The sequence of events by which a cell copies itself synthesizes other constituents of the cell and eventually splits into two daughter cells is termed the cell cycle. The cell synthesizes all its constituents in a sequential pattern to make sure the proper division and distribution of components that occurs between the two daughter cells. Therefore, we can say that the cell cycle is the period of time between the development of new daughter cells and their further division.

Stages of Cell Cycle:

The cell cycle can be sub-divided into an additional category of Interphase. Meanwhile, the Interphase can be branched into 3 further stages, such as:

G1 Phase - “Gap 1 Phase”
S Phase - "Synthesis Phase"
G2 Phase - "Gap 2 Phase"

Cell Division:

The division of the parent cells into two or more cells is called daughter cell, cell division takes place. In general, it occurs as a part of a larger cell cycle. All the cell reproduces by dividing into two, wherein each parental cell produces two daughter cells.

Stages of Cell Division:

Cell division can be widely divided into several sub-segments that result from Mitosis and Meiosis.

Mitosis or (M Phase)
Meiosis
