How many generation are required by a cell of meristem to produce 128 ...
**The Process of Cell Division in Meristem**
Meristem is a specialized tissue found in plants that is responsible for cell division and growth. It consists of actively dividing cells called meristematic cells. These cells continuously divide to produce new cells, leading to the growth of the plant. The process of cell division in meristem follows a specific pattern known as the cell cycle.
**The Cell Cycle**
The cell cycle consists of several stages, including interphase and mitosis. During interphase, the cell prepares for division by growing, replicating its DNA, and synthesizing new organelles. Mitosis is the actual division of the cell, where the replicated DNA is evenly distributed into two daughter cells.
**Calculating the Number of Cell Generations**
To determine the number of cell generations required for a meristem cell to produce 128 cells, we need to consider the process of cell division. Each cell division results in the formation of two daughter cells. Therefore, the number of cells doubles with each generation.
Let's calculate the number of generations required:
1st generation: 1 cell
2nd generation: 2 cells
3rd generation: 4 cells
4th generation: 8 cells
5th generation: 16 cells
6th generation: 32 cells
7th generation: 64 cells
8th generation: 128 cells
Therefore, it takes 7 generations for a single cell of meristem to produce 128 cells.
**Answer: (4) 7**
**Explanation:**
- The process of cell division in meristem involves a series of generations.
- With each generation, the number of cells doubles.
- By calculating the number of cells at each generation, we can determine the number of generations required to reach 128 cells.
- In this case, it takes 7 generations for a single cell of meristem to produce 128 cells.
- Therefore, the correct answer is option (4) 7.
How many generation are required by a cell of meristem to produce 128 ...
Since Mitosis is an equational division process and it produces two daughter cells from the single parent cells. Clearly, the formula (2)^n would answer the number of cells produced, where n would be the number of divisions.
Solution,
(2)^n = 128
(2)^n = (2)^7
Therefore, n=7.
It will take 7 divisions to produce 128 cells from a singe cell by mitosis.
