Anton van leeuwenhoek
botanist and zoologist, plants and animals are composed of cells
Matthias Schleiden and Theodor Schwann

Rudolf Virchow
cells are structural, functional, and reproductive units of all living things
cell theory
functions in regulation of cellular activity including division
nucleus
composed of the DNA of the cell and protein
chromosomes
the outermost living boundary of all cells
cell membrane
thick fluid composed mostly of water that fills the bulk of the cells interior
cytoplasm
synthesis, storage and transport of proteins and other chemicals within the cells
endoplasmic reticulum
protein synthesis
ribosomes
processes and packages them in transport vehicles to be moved to their final destination
golgi apparatus
digestive enzymes and allow the cell to digest engulfed food molecules or break down and recycle worm out organelles
lysosomes
catalase hydrogen peroxide
peroxisomes
production of energy
mitochondria
make up the cytoskeleton and involved in the formation of the mitotic spindle during cell division
centrioles
act as storage member
vacuole
plants contain a single large _______ _____ that may occupy as much as 90% of the volume of the cell
central vacuole
green organelles that are found inside the cells of plants
chloroplast
allows the plant to absorb light energy to power the production of food molecules by photosynthesis
chlorophyll
porous non living rigid structure
cell wall
