The Cell Nucleus:
Chromosomes are located within the nucleus. Chromosomes consists of DNA, which contains heredity information and instructions for cell growth, development, and reproduction. When a cell is "resting" i.e. not dividing, the chromosomes are organized into long entangled structures called chromatin and not into individual chromosomes as we typically think of them.
Eukaryotic Cell Structures:
- Centrioles - help to organize the assembly of microtubules.
- Chromosomes - house cellular DNA.
- Cilia and Flagella - aid in cellular locomotion.
- Cell Membrane - protects the integrity of the interior of the cell.
- Endoplasmic Reticulum - synthesizes carbohydrates and lipids.
- Golgi Complex - manufactures, stores and ships certain cellular products.
- Lysosomes - digest cellular macromolecules.
- Mitochondria - provide energy for the cell.
- Ribosomes - responsible for protein production.
- Peroxisomes - detoxify alcohol, form bile acid, and use oxygen to break down fats.
