Question | Answer |
What is the key factor that limits the size of a cell? | Ratio of surface area to volume |
When a cell reaches its size limit, what two things can it do? | Stop growing or divide |
What is the cell cycle? | A cell's process of growing & dividing |
What is interphase? | A stage of the cell cycle in which the cell grows, metabolizes, & replicates DNA |
What is mitosis? | A stage of the cell cycle in which the nucleus & nuclear material divide |
What is cytokinesis? | A stage of the cell cycle in which the cytoplasm divides and 2 new cells are formed |
What is the cell doing during the G1 stage of interphase? | Growing & metabolizing |
What is the cell doing during the S stage of interphase? | Copying DNA |
What is the cell doing during the G2 stage of interphase? | Preparing for mitosis |
What are chromosomes? | X-shaped structures that contain genetic material (DNA) |
What is chromatin? | Relaxed form of DNA |
What happens during prophase? | Chromatin condenses, nuclear membrane disappears, spindle forms |
What happens during metaphase? | Chromosomes line up along equator |
What happens during anaphase? | Chromosomes split and move toward poles |
What happens during telophase? | Chromosomes reach poles & decondense, nuclear envelopes form |
What happens during cytokinesis? | Cytoplasm divides, 2 new separate cells formed |
What are sister chromatids? | Structures that contain identical copies of DNA |
What are centromeres? | Structure at center of chromosome where sister chromatids are attached |
What is cancer? | Uncontrolled growth and reproduction of cells |
What is a carcinogen? | An agent that causes cancer |
What is apoptosis? | Programmed cell death |
What are stem cells? | Unspecialized cells that can develop into specialized cells? |
What are the two types of stem cells? | Embryonic & adult |
What is the longest phase of the cell cycle? | Interphase |
What is the longest phase of mitosis? | Prophase |
What is the shortest phase of mitosis? | Metaphase |
What happens to DNA during interphase? | Replicates |
What anchors the spindle during mitosis? | Centrioles |
How many daughter cells are produced from mitosis? | 2 |
What structure forms across the center of a plant cell near the end of telophase? | Cell plate |
What are the proteins in chromosomes that DNA wraps around? | Histones |
What is the term for cancer that has spread? | Metastasize |
What is the term for a cancerous tumor? | Malignant |
What is the term for a tumor that does not spread? | Benign |
What anchors the spindle fibers during mitosis? | Centrioles |
What connects the 2 chromatids together into one chromosome? | Centromere |
What is a cell that can grow into any other type of cell? | Totipotent |
What is the process by which a cell becomes specialized? | Differentiation |
What is an unspecialized cell that can grow into a specialized cell? | Stem cell |
What kind of cell can grow into any type of cell except totipotent? | Pluripotent |
What kind of cell can grow into the cells of a closely related cell family? | Multipotent |
