Cell Structure
Laura Whitfield and Brianna Strausser
Cell Organelles
- Organelles are things in the cell that have a specific job.
- They are like the organs of the cell
The organelles of a cell
- Nucleus-Holds the DNA of a cell and gives other organelles instructions on how to function
- Nucleous- Makes ribosomes
- Nuclear membrane- protects the nucleus
- Rough er- has ribosomes and moves things in the cell
- Smooth er- no ribosomes and moves things in the cell
- Golgi body- prepares things for export
- Ribosomes- makes proteins
- Lysosome- digestion system of the cell
- Chloroplast- photosynthesis
- Cell membrane- protects cell
- Mitochondria- makes energy
- Cell wall- protects and gives structure
- Cytopasm- nutrients and support
- Vacoule- storage for water
- Centrioles- give structure

Lipid Bilayer
- Made of phospholipids.
- Heads are hydrophillic.
- Tails are hydrophobic.
- Heads are polar.
- Tails are not polar.
- Lipid Bilayer is a major component of the cell membrane.
- Has channels in it for things to go in and out.

Cell Transport
Passive Trasport:
- Needs no energy.
- Has diffusion (Evening out number of molecules on each side).
- Osmosis has water.
- Facillitated diffusion needs a protein.
Active Transport:
- Needs energy.
- There is the Na/K pump (exports salt, brings in potassium).
- Endocytosis (eats away, helps with digestion).
- Exocytosis (large particles are entered into the cell).
