Cell

Phospholipi bilayer 

To allow for transportation through the membrane

It surrounds the nuclues.  It contains pores which control the movement of substances in and out of the nucleus.

• -nucleus
• -nuclear lamina
• -nnuclear envelope
• -rough ER

They include enzymes involved in nuclear function such as replication, transcription, DNA repair and regulation of chromatin function.

• Heterchromatin
• Euchromatin

A complete set or pair of chromosomes (46)

One set of chromosomes (26)

Contains more than two sets of homologous chromosomes.

One or two extra chromosomes.

• 1) Microfilaments (actin)
• 2) Microtubules
• 3) Intermediate filaments

• Aid in movement
•      - Local movement - mircovilli in the GI tract
•      - Sliding filament theory

• Chromosomal movement
• intracellular movement during meiosis and mitosis
• Ciliary and flagellar movement

• More stable
• No movement

• Produce ATP
• Two membranes: a smooth outer one and an inner one which is called cristae
• A matrix is enclosed by the inner membrane and contains its own DNA

Rough Endoplasmic Reticulum

Smooth ER

Membrane proteins are collected, sorted, and packaged in the Golgi Apparatus

• Synthesis and degradation of hydrogen
• B-oxidation of very long chain fatty acids
• Phospholipid exchange
• Bile acid synthesis

They site close to the surface or cells and dont allow things to penetrate the skin.

They serve as a bridge connection between cells.

allows direct connection between two cells.
