Cells
- Discovered by Robert Hooke
- Discovered a plant cell under single lens microscope by calling the mini blocks "cells"
- The different types of microscopes
- light compound microscope-$, 1000x mag. Uses light to see, 400nm resolution
- transmission electron Microscope-$$$, 10,000,000x mag. 0.2 nm res. uses beam of electrons to see dead specimens
- scanning electron microscope-$,30,000 mag. 10 nm a forced beam of high energy electrons
- cell structure
- nucleus contains DNA which has coded instructions for making proteins and running the cell
- Vacuoles and Vesicles store materials
- Ribosomes-creates p[rotein
- Rough and soft E.R assembles proteins and lipids
- Golgi Apparutus sorts and packages proteins for storage and transportation
- chloroplasts-convert solar energy to chemical energy to store food
