Stages Of Mitosis Quiz Questions

Cancer cells form masses of cells called tumors. Tumors are abnormal growths of cells that can occur in different parts of the body. These masses can be benign (non-cancerous) or malignant (cancerous). In the case of cancer, the cells in the tumor can invade nearby tissues and spread to other parts of the body, leading to the progression of the disease. Tumors can cause various symptoms depending on their location and size, and their treatment often involves a combination of surgery, radiation therapy, and chemotherapy.

The cell cycle refers to a series of events that cells go through as they grow and divide. It encompasses various phases such as interphase, prophase, metaphase, anaphase, telophase, and cytokinesis. During interphase, the cell grows, replicates its DNA, and prepares for division. The subsequent phases involve the actual division of the cell into two daughter cells. Therefore, the correct answer is "series of events that cells go through as they grow and divide."

As a cell grows, it places more demands on its DNA because it needs to replicate its genetic material to ensure proper functioning and division. It also uses up food and oxygen more quickly as it requires more energy and resources to support its increased size and metabolic activity. Additionally, as the cell grows, it has more trouble moving enough materials across its membrane because the surface area to volume ratio decreases, making it more challenging for nutrients, waste, and other molecules to diffuse across the cell membrane. Therefore, all of the above statements are true.

Prophase is a phase of mitosis where the chromatin condenses into visible chromosomes, the nuclear membrane disintegrates, and the spindle fibers begin to form. During this phase, the chromosomes become more visible and start to move towards the center of the cell. It is an essential step in mitosis as it prepares the cell for the separation of genetic material during the subsequent stages. Cytokinesis is the final stage of the cell cycle, where the cytoplasm divides into two daughter cells. Interphase is the resting phase between cell divisions, and S phase is the phase where DNA replication occurs.

During the S phase of the cell cycle, the cell's DNA is replicated. This phase follows the G1 phase and precedes the G2 phase. In the S phase, the DNA strands are unwound and each strand serves as a template for the synthesis of a new complementary strand. This ensures that each daughter cell receives an identical copy of the genetic material during cell division.

During interphase, the cell undergoes growth and prepares for cell division. This includes the synthesis of DNA, increase in cell size, and the replication of organelles. Therefore, the correct answer is "The cell grows."

During cell division, the original cell divides into two daughter cells. Each daughter cell receives a portion of the cytoplasm and organelles from the parent cell, resulting in a reduction in the original cell's volume. This allows for the efficient distribution of cellular components and ensures that each daughter cell has the necessary resources to function properly. Therefore, cell division reduces the original cell's volume.

Mitosis is the stage of cell division where the nucleus divides into two identical daughter nuclei, while cytokinesis is the division of the cytoplasm to form two separate cells. Interphase is the stage between cell divisions where the cell grows, carries out its normal functions, and prepares for division. Therefore, the correct answer is mitosis and interphase, as these are the two main stages of cell division.

Chromosomes are only visible during cell division. During this process, the chromosomes condense and become visible under a microscope. In interphase, which is the longest phase of the cell cycle, the chromosomes are not visible because they are in a less condensed state and spread out within the nucleus. The G1 phase is the first phase of interphase, so it is also not the correct answer.

Cell division does not increase the mass of the original cell. Instead, it divides the original cell into two daughter cells, each with its own copy of DNA. This allows for the growth of new cells and the expansion of tissues and organs. Cell division also increases the surface area of the original cell, which is important for nutrient uptake and waste removal. Additionally, cell division reduces the original cell's volume, as it splits into two smaller cells.
