Question

What is the speciality of the cells after mitotic cell division in geometric growth? (a) Thickened cell wall (b) Occurring of well organized growth (c) Retaining the ability to divide (d) None of these

Short answer

The speciality of cells after mitotic cell division in geometric growth is that they retain the ability to divide.

Step-by-step solution

Understand Mitotic Cell Division

Mitotic cell division is a part of the cell cycle where a single cell divides into two identical daughter cells. Each of these cells contains the same number of chromosomes as the parent cell. It is crucial for growth, maintenance, and repair of an organism.

Link to the Question

The question asks, 'What is the specialty of the cells after mitotic cell division in geometric growth?' We need to understand that in geometric cell growth, cells keep their ability to divide as each daughter cell produced by mitotic cell division is capable of further dividing.

Choose the Correct Answer

With the knowledge gained in the previous steps, the correct answer is (c) Retaining the ability to divide. After each mitotic cell division, the produced cells retain the ability to divide, enabling the geometric growth.

Key concepts

Geometric Growth

Geometric growth refers to the pattern of exponential increase in the number of cells within a population over successive cycles of division. In this context, each newly formed cell in a population retains the capacity to divide further, leading to a significant increase in cell numbers over time.
To visualize this process, think of it like a chain reaction: when one cell divides, it doesn't just double. Instead, both resulting cells can also divide and continue this pattern. This leads to a rapid increase in numbers, indicative of exponential or geometric growth.

• In exponential growth, the population doubles each cycle.
• Such growth occurs under optimal conditions, where resources are not a limiting factor.
• Essential in processes like embryonic development, tissue growth, and healing.

Cell Cycle

The cell cycle is the series of stages that a cell goes through to grow and divide. This process ensures the DNA is properly replicated and allocated into daughter cells.
The cell cycle is generally divided into two major parts:

• The interphase, where the cell prepares for division by growing and replicating its DNA.
• The mitotic phase, where the cell actually divides.

During interphase, the cell performs its normal functions, grows, and duplicates the chromosomes in anticipation of division. The mitotic phase involves several steps where a mother cell physically divides into two daughter cells, each inheriting the same number of chromosomes. Understanding the cell cycle is crucial in explaining how continuous cell division contributes to geometric growth and organismal maintenance.

Chromosomes

Chromosomes are structures within the cell nucleus that carry genetic information in the form of DNA. During cell division, precise duplication and segregation of chromosomes are critical for genetic stability.
Here's what you should know about chromosomes in the context of mitotic cell division:

• In humans, each cell typically contains 46 chromosomes arranged in 23 pairs.
• Chromosomes ensure that DNA is accurately copied and distributed during cell division.
• They play a pivotal role in ensuring that each daughter cell receives the correct genetic material.

The chromosome duplication occurs before mitotic division during the interphase, ensuring that each new cell maintains the genetic blueprint needed for normal function. Knowing about chromosomes helps us understand how genetic information is sustained across generations of cells.

Cell Division Ability

The ability of a cell to divide is central to life processes, enabling organisms to grow, develop, and repair damaged tissues. This ability is particularly highlighted in mitotic cell division.
Post-division, each new cell inherits the potential to undergo further divisions, allowing the process of geometric growth to continue repeatedly. Here are some important points about cell division ability:

• It is essential for growth, allowing organisms to increase in size over time.
• Supports the replacement of old or damaged cells, maintaining tissue health.
• A key element in healing, assisting in the repair of tissues after injury.
Cells retaining the ability to divide are vital for organisms, balancing the need for growth and stable maintenance of tissues across their lifespan. This ability is what makes geometric growth possible, ensuring that life can flourish and sustain.
