Asexual/Mitosis Quiz
Term | Definition |
---|---|
Asexual reproduction | one parent creates two indentical offspring and the same amount of DNA |
Sexual reproduction | two parents create offspring that are similar but different from the parents. |
Centrioles | pull apart chromosomes during Anaphase (the things at the north and south poles) |
Mitosis | division of cells creating identical copies. |
Interphase | most of the cell cycle happens in interphase, its the longest portion of it, cells grow and duplicate DNA and organelles |
Prophase | nucleus disappears, chromosomes wind up |
Metaphase | chromosomes line up in the middle, spindle apparatus and centrioles appear and attach to chromosomes. |
Anaphase | chromosomes separate to form sister chromatids, they are pulled toward the centrioles on opposite ends |
Telophase | nucleus starts to reappear , chromosomes start to unwind, cytoplasm starts to separate (looks like a telephone) |
Cytokiniss | cytoplasm seperates by forming a cleavage furrow in animal cells and a cell plate in plant cells. |
Differentiation | Cells speacialize to form different tissues for different functions |
Apoptosis | controlled cell death |
Ccncer | disorder where body cells lose the ability to control cell growth |
mitosis | Interphase, prophase, metaphase, anaphase, telophase |
Why would it be a problem if all of the cells were the exact replica of each other? | This could be a problem because if everything is copied and cells are diseased, many cells will have that disease too. |
why do multicellular celled organisms go through mitosis | Grow, heal, and replace old cells |
