1. light microscope: microscope that uses a beam of light passing
through one or more lenses to magnify an object
2. electron microscope: microscope that forms an image by focusing
beams of electrons onto a specimen
3. scanning microscope: a microscope that produces an enlarged, three-
dimen- sional image of an object by using a beam of electrons rather
than light
4. Model organisms used in biology: E.coli, yeast, arabidopsis,
drosophila, c. elegans, zebrafish, mice
5. E. coli: bacteria
6. yeast: unicellular fungi
7. Arabidopsis thaliana: flowering plant
8. Drosophila: fruit fly
9. C. elegans: worm
10.Zebrafish: used in the study of developmental neuroscience for its
transparent eggs
11.double membrane organelles: nucelus, mitochondria, chloroplast
12.Nucleus: A part of the cell containing DNA and RNA and responsible
for growth and reproduction
13.Mitochondria: Powerhouse of the cell, organelle that is the site of ATP
(energy) production
-smooth outer membrane and highly complex inner membrane
-inner membrane contains most of the proteins responsible for cellular
respiration
14.Chloroplast: organelle found in cells of plants and some other
organisms that captures the energy from sunlight and converts it into
chemical energy
-outer and inner membrane
-thylakoids: flattened sacs of membrane containing chlorophyll
15.Single membrane organelles: endoplasmic reticulum, golgi apparatus,
internal membrane system, vacuoules, lysosomes, peroxisomes
16.Endoplasmic Reticulum: A system of membranes that is found in a
cell's cytoplasm and that assists in the production, processing, and
transport of proteins and in the production of lipids.
-rough ER makes proteins, has bound ribosomes
-smooth ER stores proteins and lipids, lacks bound ribosomes
-ribosomes perform protein synthesis
17.Golgi apparatus: stack of membranes in the cell that modifies,

and packages proteins
from the endoplasmic reticulum
-small vesicles of membrane pinch off
-routing of newly synthesized proteins to the correct cellular
compartment
