Biology 1090: Lecture 2
January 7, 2015
Read section 1.1-1.4
Basic Properties of Cells
Highly complex and organized
Activity controlled by a genetic program (tells the cell how to run and make
a copy of itself)
Can reproduce or make copies of itself
Assimilate and utilize energy (ATP is like the currency of the cell, needed
for most functions and cycles)
Carries out many chemical reactions (ex. Enzymes)
Engage in mechanical activities
oTransport things throughout the cell, and depending on the cell the
entire cell can move
Respond to stimuli (receptors are how cells react to stimuli)
Capable of self regulation
They evolve
Both have nucleus mitochondria, both bound by a plasma membrane
Only plants have chloroplast, cell wall (made of cellulose
Difference Between Eukaryotic and Prokaryotic
Prokaryotic are bacteria, usually smaller, structurally simpler, have flagella,
no end plasmid reticulum, golgi body, lysosomes
