Parts Of The Eukaryotic Cell.

Front 1

nucleus

Back 1

COMPOSITION:
Non-reproducing=threadlike mass called chromatin

Reproducing=mass thickens into chromosomes
*Has DNA and porous membrane to communicate with cytoplasm

FUNCTION: carries the genetic information

Front 2

cell membrane

Back 2

COMPOSITION:
Phospholipid bilayer that makes cell separate unit

Viscosity of olive oil for fluidity

FUNCTION:
Proteins- extend through membrane to transport in&out

Carbs- receptor cites

sterols-help w/osmotic protection NOT IN PROKARYOTIC CELLS

*Compartmentalization & selective permeability

Front 3

endoplasmic reticulum

Back 3

COMPOSITION:
Membranous network of sacs with nucluear membrane

FUNCTION:
SMOOTH ER- synthesizes fats & phospholipids (liver/muscle)

ROUGH ER- attached to ribosomes/proteins formed in ribosomes are folded into ER and transported

Front 4

ribosome

Back 4

COMPOSTION: tiny round cytoplasmic particle composed of RNA & protein

FUNCTION: site of protein synthesis as directed by mRNA

Front 5

golgi complex

Back 5

COMPOSITION: membranous sacs in stacks

FUNCTION:
Modifies proteins

-glycoproteins(sugars with proteins)
-lipoproteins(fats with proteins)

Front 6

lysosome

Back 6

COMPOSITION:
membrane bound sructures that contain up to 40 different types of digestive enzymes

membrane is not a bilayer

FUNCTION:
enzymes catalyze the breakdown of many types of molecules

in phagocytic white blood cells, help digest phagocytized bacteria

Front 7

vacuole

Back 7

COMPOSITION:
membrane-enclosed structures

FUNCTION:
storage units for proteins & sugars or for toxic metabolic waste

Front 8

mitochondria

Back 8

COMPOSITION:
Double membrane bound structure

Respiratory/electron transport chain is embedded in inner membrane with ATP synthase
Inner membrane folded for more surface area for chem. reactions

FUNCTION:
Has 70 S ribosomes

Own DNA

Reproduces independently

***powerhouse of cell

***provides the cell with energy/breaks down food molecules to make ATP

Front 9

cytoskeleton

Back 9

COMPOSITION:
Has tonofibrils

Filaments of terminal web

FUNCTION:
Internal reinforcement in cytoplasm

Front 10

chloroplast (plants)

Back 10

COMPOSITION: membrane bound & contains chlorophyll

FUNCTION:
Conserves light energy from sun

Fixes CO2 by photosynthesis

Forms C6H12O6

Front 11

cell wall (plants and fungi)

Back 11

COMPOSITION:
Rigid structure that lies on outside of cell

Joined to plasma membrane of plant cells & MOST PROKARYOTIC CELLS

FUNCTION:
Protects the cell & maintains its shape

Front 12

cilia

Back 12

COMPOSITION:
minute hair-like processes that extend from cell

9 pairs of microtubules around a core of 2 microtubules

FUNCTION:
Beats rhythmically to move cell

Moves fluid or mucus over surface

Front 13

flagella

Back 13

COMPOSITION:
hair-like projections that extend from some unicellular organisms

FUNCTION: aid in movement
