Four fundamental parts

Cell membrane
Cytoplasm
Organelles
The inclusion

1

Cell membrane

A thin envelop that regulates the entry and exit of various molecules
Double membrane made of phosolipids
Encloses the liquid phase of the cell

2

Cytoplasm

Liquid phase of cell
Contains the organelles

3

Nucleus

Found at the center (not always)
Contains chromatin in its center

4

Chromatin

Loosely coiled DNA

5

Nucleoplasm

Liquid phase of the nucelus
Suspends the chromatin

6

Nuclear membrane

Limiting envelope surrounding the nucelus
Contains pores allowing for molecules to pass btw the cytoplasm and nucleoplasm

7

Nucleoli

In the nucleus
One to four inside
Concerned with protein synthesis

8

Ribosomes

Produced by rough endoplasmic reticulum as projections on its outside surface

9

Rough endoplasmic reticulum

Protein synthesis

10

Smooth endoplasmic reticulum

Lipid and steroid synthesis

11

Golgi appartus

Package protein released from the rough endoplasmic reticulum

12

Cytoplasmic secretory vesicles

Packaged protein ready for cellular use or export

13

Mitochondria

Double layered sphe

14

Polyribosomes

Groups of ribosomes that have similar structure abd function to ribsomes from Rough ER but freely float

15

Centrioles

In cells that can duplicate
Tubules arranged at right angles to one another
Control movement of chromosomes during cell duplication

16

Inclusions

Products that have accumulated in the cytoplasm of particular cells
Ex: fat droplets in liver cells that encounter high lvls of alcohol over extended periods of time
