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
