A type of cell division that produces two daughter cells with the same number of chromosomes as the parent cell, essential for growth, repair, and maintenance in multicellular organisms. | Mitosis |
What is mitosis? | A type of cell division that creates new cells with the same number of chromosomes as the parent cell. |
The process by which a parent cell divides into two or more daughter cells. | Cell Division |
What does mitosis allow multicellular organisms to do? | Grow and repair. |
The process of increasing in size or number, typically through cell division and enlargement. | Growth |
Why is mitosis essential for multicellular organisms? | It allows for growth and replacement of old or damaged cells to maintain the body. |
The process by which organisms produce offspring without the involvement of gametes or mating, resulting in genetically identical clones of the parent organism. | Asexual Reproduction |
What is asexual reproduction? | The process by which organisms produce offspring without mating, resulting in genetically identical clones of the parent. |
The young of an organism produced by asexual or sexual reproduction. | Offspring |
How many parents are involved in asexual reproduction? | One parent. |
Sex cells, such as sperm and egg, that fuse during sexual reproduction to form a zygote. | Gametes |
What is the role of gametes in asexual reproduction? | There is no involvement of gametes in asexual reproduction. |
Genetically identical organisms produced by asexual reproduction. | Clones |
What are the offspring produced in asexual reproduction? | Genetically identical clones of the parent. |
Single-celled microorganisms that reproduce asexually through binary fission. | Bacteria. |
What is an example of organisms that reproduce asexually? | Bacteria. |
The series of events that take place in a cell leading to its division and duplication. | Cell Cycle |
What is the cell division process used in asexual reproduction? | Mitosis. |
What is the cell cycle? | The series of events that occur in a cell leading to its division and duplication. |
The phase of the cell cycle during which the cell grows, replicates its DNA, and prepares for cell division. | Interphase |
What happens during interphase? | The cell grows, replicates its DNA, and prepares for cell division. |
The process by which DNA makes a copy of itself during cell division. | DNA Replication |
What occurs during DNA replication? | The DNA in chromosomes is replicated, resulting in two identical copies of each chromosome. |
The process of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus. | Mitosis |
What is mitosis? | The process of cell division that results in two daughter cells with the same number and kind of chromosomes as the parent nucleus. |
The first stage of mitosis during which the chromosomes condense and become visible, and the nuclear envelope breaks down. | Prophase |
What happens during prophase? | The chromosomes condense, becoming visible, and the nuclear envelope breaks down. |
Thread-like structures made of DNA and protein that carry genetic information. | Chromosomes |
What are chromosomes? | Thread-like structures made of DNA and protein that carry genetic information. |
The second stage of mitosis during which the chromosomes line up along the center of the cell. | Metaphase |
What happens during metaphase? | The chromosomes line up along the center of the cell. |
The third stage of mitosis during which the pairs of identical chromatids separate and move to opposite sides of the cell. | Anaphase |
What happens during anaphase? | The pairs of identical chromatids separate and move to opposite sides of the cell. |
The final stage of mitosis during which new membranes form around each set of chromosomes. | Telophase |
What happens during telophase? | New membranes form around each set of chromosomes, and the cell prepares for cytokinesis. |
Near the end of telophase, the cytoplasm and cell membrane divide to give 2 new cells. | Cytokinesis |
What happens during cytokinesis? | Near the end of telophase, the cytoplasm and cell membrane divide to give 2 new cells. |
The process of cell division that results in two daughter cells, each having the same number and kind of chromosomes as the parent nucleus. | Mitosis |
What is mitosis? | The process of cell division that results in two daughter cells, each having the same number and kind of chromosomes as the parent nucleus. |
The cells produced as a result of cell division, each having identical genetic information to the parent cell. | Daughter Cells |
What are daughter cells? | The cells produced as a result of cell division, each having identical genetic information to the parent cell. |
Having two sets of chromosomes, typically one set from each parent. | Diploid. |
What is the ploidy of the parent cells and daughter cells in mitosis? | Diploid. |
The degree of similarity in genetic makeup between individuals or between cells within an individual. | Genetic Identity |
What does mitosis produce in terms of genetic identity? | Genetically identical diploid daughter cells. |
A group of diseases characterized by uncontrolled growth and spread of abnormal cells. | Cancer |
What is cancer? | A group of diseases characterized by uncontrolled growth and spread of abnormal cells. |
The process by which a parent cell divides into two or more daughter cells. | Cell Division. |
What process may become uncontrolled if certain genes inside a cell stop working? | Cell Division. |
Units of heredity that are passed from parent to offspring and contain instructions for building and maintaining an organism. | Genes |
What controls the rate of mitosis inside a cell? | Genes. |
Abnormal masses of tissue resulting from uncontrolled cell division. | Tumors |
What are tumors? | Abnormal masses of tissue resulting from uncontrolled cell division. |
A change in the DNA sequence of a gene or chromosome. | Mutation |
What causes cancer? | Changes to genes known as mutations. |
Substances capable of causing cancer in living tissue. | Carcinogens |
What types of chemicals can increase the likelihood of mutations that lead to cancer? | Carcinogens, such as those found in cigarette smoke. |
