Across
- 3. paired homologous chromosomes with two chromatids each
- 8. the phase where the chromosomes uncoil, the spindles disappear, the nuclear envelope reappears (there are now two of them, one for each cell)
- 9. Fission a single celled organism splits into two equally sized halves, two individuals are formed from one parent
- 10. the resting period in between meiosis 1 and meiosis 2 (aka interphase 2)
- 13. some organisms reproduce by dividing, the point is to make more of a cell
- 16. the last phase after PMAT; the separating of the cell
- 17. the phase before the PMAT; occurs before mitosis begins; cell spends most of it’s life in this stage; the cell getting ready to replicate
- 18. the phase where each centromere divides; each 2 chromatid chromosomes becomes two 1 chromatid chromosomes which are pulled to opposite poles by the spindles
- 20. process that occurs in sexually reproducing organisms; the nucleus divides into four nuclei that each have half the chromosome number; divides twice
Down
- 1. cells are produced so that organisms can grow
- 2. the phase where chromosomes line up on the equator of each spindle and the centromeres move to opposite ends of the cell
- 4. Reproduction special cells in a plant repeatedly divides, cells produce a structure, structure grows into an identical plant to the parent
- 5. having a single set of unpaired chromosomes
- 6. parent produces single cells and releases them, the cells will grow into an organism if given the right conditions
- 7. a piece of the parent breaks off, the broken piece then grows into a new organism
- 9. offspring grows from parent; detaches from parent; becomes individual organism
- 11. cells that are damaged or dead need to be replaced which will occur through cellular division
- 12. the phase where chromosomes condense, the nuclear envelope disappears, centrioles move to opposite sides of the cell, the spindle forms and attaches to centromeres on the chromosomes
- 14. only one parent; only one gender; offspring are genetically identical to parent, offspring are clones
- 15. results in two daughter cells that have the same number and kind of chromosomes as the parent cell; only divides once
- 19. Division the division of a cell into two daughter cells with the same genetic material
