What happens after the nucleus divides?
13. After a new nuclear membrane forms during telophase of mitosis or meiosis, the cytoplasm_________ divides, resulting in two cells. In plant cells, cytokinesis occurs when nucleus has divided and cell plate is formed.
What happens when eukaryotic cells divide?
In particular, eukaryotic cells divide using the processes of mitosis and meiosis. Mitosis is common to all eukaryotes; during this process, a parent cell splits into two genetically identical daughter cells, each of which contains the same number of chromosomes as the parent cell.
What is the end result of cell division in eukaryotes?
Cell Division in Eukaryotes Though cell division in all cells results in one cell becoming two cells, cell division in eukaryotic organisms is very different from that in prokaryotes, mainly because of the many chromosomes in the nuclei of eukaryotic cells.
What is the correct order of eukaryotic cell division?
The division cycle of most eukaryotic cells is divided into four discrete phases: M, G1, S, and G2. M phase (mitosis) is usually followed by cytokinesis. S phase is the period during which DNA replication occurs.
What is the function of nucleus in cell division?
The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell’s genetic material.
What happens to the nucleus during mitosis?
At the beginning of mitosis, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down, resulting in the release of most of the contents of the nucleus into the cytoplasm. …
What is a cell division in eukaryotic cells?
Eukaryotes have two major types of cell division: mitosis and meiosis. Mitosis is used to produce new body cells for growth and healing, while meiosis is used to produce sex cells (eggs and sperm). Meiosis will be discussed in a later chapter. During interphase, the cell grows and DNA is replicated.
What is the first step of cell division in eukaryotic cells?
Cell Division in Eukaryotes Its organelles are also duplicated. Then, when the cell divides, it occurs in two major steps: The first step is mitosis, a multi-phase process in which the nucleus of the cell divides. During mitosis, the nuclear membrane breaks down and later reforms.
What are the phases in cell division?
Today, mitosis is understood to involve five phases, based on the physical state of the chromosomes and spindle. These phases are prophase, prometaphase, metaphase, anaphase, and telophase.
