Cell Stuff

Eukaryote organism whose cells contain nuclei
prokaryote unicellular organism lacking a nucleus
organelle specialized structure that performs important cellular functions within a eukaryotic cell
nucleus the center of the atom which contains the protons and neutrons; in cells, structure that contains the cell's genetic material (DNA) and controls the cell's activities
cell collection of living matter enclosed by a barrier that separates the cell from its surroundings; basic unit of all forms of life
cytoplasm material inside the cell membrane—not including the nucleus
ribosome small particle in the cell on which proteins are assembled; made of RNA and protein
lysosome cell organelle filled with enzymes needed to break down certain materials in the cell
vacuole cell organelle that stores materials such as water, salts, proteins, and carbohydrates
diffusion process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated
Interphase The stage of the cell cycle that takes place before cell division occurs; the cell grows, copies its DNA & prepares to divide.
prophase first phase of mitosis in which chromosomes become visible and nuclear membraine disappears
anaphase the third part of mitosis, during which the chromosome paris separate and move towards opposites poles
telopahse 4th and final phase of mitosis, during which the chromosomes begin to disperse into a tangle of dense material
Metaphase connects the centromere of each chromosome to the two poles of the spindle.
