Woodall's cell review set

STUDY
PLAY
Nucleus
control center; directs all cell activities
Cell Membrane
boundary of cell; controls what enters and leaves the cell
Cell Wall
boundary of plant cell; provides structure
Cytoplasm
fills up remaining space; jelly-like; where some cell processes take place
Mitochondria
powerhouse of the cell; provides energy
Ribosomes
protein factories
Endoplasmic Reticulum
transportations system
Golgi Bodies
receiving and packaging
Chloroplast
captures sun to produce sugars (food) for the cell
Lysosomes
digests wastes; destroys unwanted or unneeded organelles or substances
Prokaryotic Cell
a cell that does not contain a membrane bound organelles like bacteria
Eukaryotic Cell
a cell that contains membrane bound organelles
Nucleolus
contains RNA and makes ribosomes
Vacuole
storage area; stores water, wastes, and other materials; larger in plant cells
Chromosomes
genetic material (DNA)
cell
The basic unit of life
Robert Hooke
Created a microscope and "discovered" cells
Schleiden and Schwann
German scientists who found plant and animal cells had similarities
Rudolf Virchow
proposed that cells come from preexisting cells
water
makes up 70% of all cells. Surrounds cells and helps to insulate them.
Nucleic Acid
macromolecule that contain genetic information (DNA and RNA)
DNA
Genetic material that controls cell growth, cell reproduction and cell processes
RNA
Gentic material that controls the production of proteins
Protein
chains of amino acids
Function of protein
communication, cell transport, chemical breakdown of substances, and structural support
Lipid
does not dissolve in water. stores energy, protective membranes, and cell communication
carbohydrates
chains of sugar; provides stored energy, structural support in plants, and communication between cells
Cell theory
all organisms are made of cells, cells are the basic unit of life, cells come from preexisting cells
