Cards

Term
Cell Theory
Definition
  1. Cells are the basic Functunal units of Life
  2. Cells are the basic Structural units of life 
  3. All cells come from pre-existing cells

 

Term
Cell Membrane
Definition
barrier between the inside & the outside environment that surrounds the cell. It allows water and very small materials to diffuse through it.
Term
Cytoplasm
Definition
the fluid content of the cell in which organelles are suspended like fruit pieces in jello
Term
Nucleus
Definition

"Control Center" of the Cell.

  1. Contains the DNA (master blueprint)in Chromosomes.

 

Term
Endoplasmic Reticulum (ER)
Definition
The "roadway" of the cell on which Ribosomes attach, giving them an address.
Term
Ribosomes
Definition
"Protein Factories" of the cell
Term
Golgi {Bodies/Center/Complex}
Definition

"Packaging Center"of the cell.

Looks like stack of smashed hubcaps.

Term
Mitochondria
Definition

"Power-House" of the cell.

Converts food energy to ATP-bond energy units usable for reactions within the cell.

Term
Lysosome
Definition
"Bag of destructive enzymes" gathered and packaged in the Golgi Complex.
Term
Cell Wall
Definition

Cell organelle of Plants & Fungi (and Bacteria)

 

Gives structural strength, protection & support.

 

In plants it is made up of Cellulose a complex carbohydrate. The "wood" that is all that remains when a tree dies.

 

located ...Outside of the Cell Membrane. Has small holes or "pores" thru it so material can get to the cell membrane to pass thru to or out from the cell

Term
Chloroplast
Definition

Found only in Plants & Algae

 

 Organelle where photosynthesis takes place.

 

Green color = Chlorophyll is a green pigment

Term
Prokaryotic Cell
Definition

P=Primative & Prokaryotic

(ALL bacteria) cells

  1. Cells without membrane bound structures
Term
Eukaryotic Cells
Definition

"You have Eukaryotic cells"

Kingdoms:Plantae,Animal, Fungi, Protista Cells

  1. Cells with Membrane bound structures
  2. Organized = Effiecient = Larger Cells
Term
Organelle
Definition
a membrane bound area within a Eukaryotic cell that has a job or function.
Term
Centriole
Definition

Only found in Animal Cells

Important in Cell Division [Mitosis & Meiosis]

Term
Chromosomes
Definition

The genetic material (DNA) that carries ALL the instructions for construction of Structrial Proteins and Enzymes found within the organism

 

Found in the Nucleus where they are kept safe & secure

 

In pairs (one from each parent) of Long coiled double-helix strands

Term
Nucleolus
Definition

The site of Ribosome production within the Nucleus of a Eukaryotic Cell

 

In diagrams looks like a ball inside of the Nucleus ball
