Cell cycle, endo & exocytosis, cell organization.


the process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell


process by which vesicles release their contents outside the cell

hypertonic solution

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

cell cycle

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

organ system

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 chromotid

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


any malignant growth or tumor caused by abnormal and uncontrolled cell division


sequence of DNA that codes for a protein and thus determines a trait

hypotonic solution

(of a solution) having a lower osmotic pressure than a comparison solution

isotonic solution

(used of solutions) having the same or equal osmotic pressure
