14.1: Cell Cycle and Cell Division. Cell division is the process in which one cell, called the parent cell, divides to form two new cells, referred to as daughter cells. How this happens depends on whether the cell is prokaryotic or eukaryotic.
The continuity of life from one cell to another has its foundation in the reproduction of cells by way of the cell cycle. The cell cycle is an orderly sequence of events that describes the stages of a cell’s life from the division of a single parent cell to the production of two new daughter cells.
When cells divide, they make new cells. A single cell divides to make two cells and these two cells then divide to make four cells, and so on. We call this process "cell division" and "cell reproduction," because new cells are formed when old cells divide. The ability of cells to divide is unique for living organisms. Why Do Cells Divide?
New organisms don't just appear out of nowhere—they are the result of reproduction! In this unit, we'll learn about sexual and asexual reproduction, fertilization, and development. We'll also explore mitosis and meiosis, which are the cellular processes that allow organisms to grow and reproduce.
Jun 20, 2024 · Mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells. Strictly applied, the term is used to describe the duplication and distribution of chromosomes, the structures that carry the genetic information.
During development and growth, mitosis populates an organism’s body with cells, and throughout an organism’s life, it replaces old, worn-out cells with new ones. For single-celled eukaryotes like yeast, mitotic divisions are actually a form of reproduction, adding new individuals to the population.
Key terms. The cell cycle. In eukaryotic cells, the cell cycle is divided into two major phases: interphase and mitosis (or the mitotic (M) phase). Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis.
Jun 16, 2024 · Reproduction, process by which organisms replicate themselves. Reproduction is one of the most important concepts in biology: it means making a copy, a likeness, and thereby providing for the continued existence of species. Learn more about the process of reproduction in this article.
Dec 8, 2016 · Mitosis is the step in the cell cycle that the newly duplicated DNA is separated, and two new cells are formed. This process is important in single-celled eukaryotes, as it is the process of asexual reproduction.
This chapter introduces two types of cell divisions. First, it explains mitosis and then meiosis. This chapter also explains why cells divide and how the divisions are regulated. The errors in the division may lead to diseases, such as leukemia.
