Eukariotic cells vs Prokaryotic cells |
-USUALLY larger than prokaryotic cells -prokaryotic cells do not have a nucleus, eukariotic cells do |
|
|
The Nucleus |
-The 'brain' of the cell |
|
|
Three major parts of the nucleus |
-Nuclear envelope -Chromatin -Nucleolus |
|
|
Nuclear Envelope |
-Like the membrane of the nucleus, but has many holes for RNA to travel through -double membrane |
|
|
Chromatin |
-strands of DNA wrapped around protein -contains genetic material, like a blueprint |
|
|
Chromosomes |
-chromatin that was compacted during cell division |
|
|
Nucleolus |
-Center part -Makes ribosomes |
|
|
Cytoplasm |
-made of organelles and cytosol |
|
|
Cytoskelliton |
-gives shape to eukaryotic cells
-made up of three microfibers -four main jobs |
|
|
The three microfibers |
-Thin microfilaments -Medium sized intermediates filaments -Thick microtubules |
|
|
The four main jobs of cytoskelliton |
1. maintaining shape of the cell 2. providing movement for the cell (see cilia and flagellum) 3. providing organelle movement 4. making cell division |
|
|
Cilia |
-works like the oars on a row boat -move cell through fluid or fluid through the cell |
|
|
flagellum |
-work like the motor on a motorboat, whip like tail -longer than cilia -move the cell through fluid or fluid past the cell |
