| Term | Definition |
|---|
| cellular reproduction | process wherby parent cell divides to produce 2 to 4 new daughter cells |
| nucleus | control center for the cell |
| nuclear membrane | double membrane surrounding the nucleus |
| cellular differentation | determines what form it will take at maturity |
| cellular metabolism | instructions that guide the life processes of the cell |
| chromatin material | thick nuclear material seen in nucleus only when it is not actively dividing |
| chromosomes | shortened thickened threadlike bodies in the nucleus the are clearly visible when the cell is actively dividing |
| chromatin material | contains DNA, histones and water |
| chromosomes | contain DNA and histones, basic units of heredity |
| chromonemata | long thin filament in chromosome |
| chromameres | globlar swellings located on the chromonemata |
| chromatid | each half of a duplicated chromosome |
| centromere | each half of duplicated chromosome is held together by a constricted area |
| centromere | you count these to determine number of chromosomes |
| 46 chromosomes or 23 pair | each normal human body cell contains this # of chromosomes |
| homologous chromosomes | the same size, shape and contain the same types of genes |
| sex chromosomes | determine the sex |
| diploid | full complement of chromosomes - 2 of each type |
| haploid | half the full number of chromosomes - 1 of each type |
| histones | responsible for packing the DNA so that it can fit into such a small space |
| nucleolus | dark stainging dense masses of irregular shape and size in nucleus that are visible only when the cell is not dividing |
| nucleolus | in nucleus, made up of RNA and proteins, produce ribosomes, no membrane |
| cytoskeleton | interconnecting system of protein threads that crisscross in the cytoplasm from the nucleus to the cell membrane |
| microtubules | protein called tubulin, they make up cilia, flagella, spindle fibers |
| microfilaments | protein called actin, they make cleavage furrows, pseudopods, pinocytic depressions |
| intermediate filaments | protein called keratin, involved in cell shape and make up the structural parts of the cell |
| cilia and flagella | function in movement, made up of protein, have 9+2 arrangement |
| centrioles | small dark bodies located just outside the nucleus and arranged at right angles to each other. animal cell, govern the plane of cell division |
| basal body | produce the cilia and flagella |
| centrioles | produces the basal body |
