Basic structural and function unit of living organism

1st person use to term cell

1st observed living cell

Discovered Nucleus

Pre-existing cell

All plants and animals tissues were compound

Undeveloped nucleus, only one chromosome, membrane bound organells are abesent but performing a necessary life

Well developed nucleus, more than one chromosome, membrane bound organelles are present, unique role and containing a specific complement of proteins and other molecules

Cell communication, regulates material movements into and out of the cell

It contains DNA that serves as the genetic material for directing protein synthesis

Consists of the RNA AND PROTEINS which function in ribosomal unit assembly.

It surround the chromatin and the nucleolu

Discovered fluid content of cell

It is responsible for various cellular process

Are involved in the protein synthesus

Packages and sorts materials arrive from endoplasmic reticulum in transport vesicles

MODIFIES, transports and store PROTEINS produces by ATTACHED RIBOSOMES

SYNTHESIZES, transport and stores LIPIDS, DETOXIFIES DRUGS; FORM VESCES AND PEROXISOMES (lack)

Production of energy (POWER OF THE HOUSE)

DIGEST microbes or materials by the cell (SUICIDE BAG)

Biosynthesis of cholesterol

Structural support

Maintain cell shape

Mechanical support to structure like nucleus and plasma membrane

Bulk movements of substances OUT of the cell by fuision of secretory vesicles w/ plasma membrane

Bulk movements of substances INTO the cell by vesicles FORMING AT THE PLASMA MEMBRANE

Maintain integral structural support and organization cells

4 TYPES OF CELL DIVISION-MITOSIS

Identical to the mother nucleus
