process by which vesicles release their contents outside the cell
a solution in which the concentration of solutes is greater than that of the cell that resides in the solution
the third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles
the regular sequence of growth and division that cells undergo.
in animal cells, a cytoplasmic organelle that organizes the mitotic spindle fibers during cell reproductions
a specialized condensed region of each chromosome that appears during mitosis where the chromatids are held together to form an X shape
the readily stainable substance of a cell nucleus consisting of DNA and RNA and various proteins
threadlike structure within the nucleus containing the genetic information that is passed from one generation of cells to the next
the division of the cytoplasm during the proceses of cell division
a period between two mitotic or meiotic divisions during which the cell grows, copies its DNA, and synthesizes proteins
second phase of mitosis, during which the chromosomes line up across the center of the cell
cell division in which the nucleus divides into nuclei containing the same number of chromosomes
group of tissues that work together to perform closely related functions
A group of organs that work together in performing vital body functions.
first and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus
Sister chromatids are two identical copies of a single chromosome that are connected by a centromere.
(biology) tiny fibers that are seen in cell division
the final stage of mitosis or meiosis, during which a nuclear membrane forms around each set of new chromosomes
group of similar cells that perform a particular function
