Mention the 3 main functions of the cytoskeleton
Structure, movement and recognition
What is the function of the RER?
Rough Endoplasmic Reticulum (studded with ribosomes) in charge of protein synthesis and transport.
What is the function of the SER?
SER: Smooth Endoplasmic Reticulum (no ribosomes) in charge of metabolism, synthesis of hormones and detoxifies the cell.
What is the function of Golgi apparatus?
RER vesicle fuses with the Golgi apparatus. The Golgi apparatus modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum.

What is the function and content of the nucleus?
The nucleus controls most cell processes and contains DNA (Chromatin)
What's chromatin ?
Chromatin: uncoiled DNA + proteins (the form DNA is in when it is not condensed into a chromosome)
Proteins are carried from RER to Golgi in _______________
Vesicles
Why are mitochondria called “powerhouses” of the cell? Name the process and the name of the energy molecule produced.
They make energy available from food to fuel cell activities in form of ATP
This is a phospholipid. The heads are attracted to water. What's the name of this property?
Hydrophilic (Hydrophilia)
Name this type of cell with no nucleus
Prokaryotic cell
This is a phospholipid. The tails repel water. What's the name of this property?
Hydrophobic (Hydrophobia)
