The Endoplasmic Reticulum (ER)

a) a network of tubular canals that connects the nucleur membrane with the cell membrane
b) functions like a little circulatory system within the cell for transport of molecules

Smooth ER

1- contains enzyme systems involved in lipid and steroid metabolism

Rough ER

1- studded with ribosomes
-ribosomes are composed mostly of RNA are synthesised in the nucleolus of the cell
-ribosomes are where the proteins are synthesised

Storage Vacuoles and Vesicles

a) act as storage sites

Lysosomes
a) formed from sacules of Golgi complex
b) contain hydrolytic enzymes
c) fuse with food vacuoles
d) digest substances within the cell

Mitochondria
a) 12-1,000 mitotic per cell, large, bean-shaped organelles
b) the inner membrane covered with enzymes containing folded membranes inside
c) site of cellular inspiration; the generation of ATP
d) contains its own DNA and ribosomes
e) active cells contain large numbers

Golgi Apparatus/Complex
a) formulates special substances such as mucous
b) layers of membranes, stacks of membranous saccules
c) stores, modifies and packages chemical substances formed in the E.R.

Centrioles
a) found only in animal subsatnces
b) involved in cell division
c) rod-shaped
d) positioned near to nucleus
e) help seperate the chromosomes in cell division

Organelles for Motion:
Flagellum
a) a long whip-like extencion from the cell
b) moves the cell e.g, human sperm cell
c) found in sperm

Cillia
a) hair-like projecions from te cell
b) create movement around the cell
c) cells like those in the respiratory pathways and fallopian tubes
