NCERT Exemplar Class 11 Biology Chapter 10 Solutions: Cell Cycle and Cell Division
NCERT Exemplar Solutions for Class 11 Biology Chapter 10 illustrates the concepts of cell cycle and cell division. The cell theory proposes that new cells devise from pre-existing cells. This procedure is commonly known as cell division. The main topics in the chapter of NCERT Class 11 Biology Exemplar include cell cycle, M Phase, meiosis, the significance of meiosis, and the significance of mitosis. In this chapter, you will also come across important terms like Karyokinesis, Cytokinesis, and many more.
Chapter 10 – Cell Cycle and Cell Division has 4 main exercises with around 43 exemplar problems in total. Answering the questions, you will come to know about the brief concepts of the cell cycle and cell division. Since the solutions provided by our experts at Instasolv are concept-focused rather than question-focused, they can also be used to study the other main topics covered in the chapter.
Following our NCERT Exemplar Problems Class 11 Biology Solutions, you will get the step-by-step methods to answer the question easily. So, if you feel stuck while preparing for Chapter 10, then refer to our exemplar problems with solutions at any time and from anywhere. Also, you can access all these solutions for free.
Important Topics for NCERT Biology Exemplar Solutions Class 11 Chapter 10 – Cell Cycle and Cell Division
A cell cycle is a sequence of proceedings that happens in a cell as it develops and divides. A cell spends most of its time in what is known as interphase, and during this time it develops, duplicates its chromosomes, and formulates for cell division. The cell then leaves interphase, experiences mitosis, and finishes its division.
M Phase is referred to as the Mitotic Phase. During this phase, the cell divides its duplicate DNA and cytoplasm to make two fresh cells. M phase comprises two separate division-related procedures including mitosis and cytokinesis.
Significance of Mitosis
Mitosis is a procedure where a single cell splits into two identical daughter cells. The purpose of mitosis is cell regeneration, cell growth, and asexual reproduction.
Meiosis refers to a procedure where a single cell divides twice to develop four cells comprising half the original amount of genetic facts. These cells are our sex cells including the sperm in males, eggs in females. During meiosis one cell gets divided twice to form four daughter cells.
Significance of Meiosis
Meiosis is accountable for the development of sex cells or gametes that are accountable for sexual reproduction. It stimulates the genetic information for the progress of sex cells and neutralizes the sporophytic information. It continues the continuous number of chromosomes by splitting the same.
During the process of cell division, the method of the partition of a cell’s nucleus into the daughter cells is referred to as Karyokinesis. In this process, the DNA shortens and the chromosomal substance divides equally into two halves.
Cytokinesis refers to the physical procedure of cell division, which splits the cytoplasm of a parental cell into two daughter cells. This process happens alongside with two types of the nuclear division known as mitosis and meiosis, which also happen in the animal cells.
