Chapter 3 (cont) Lecture Notes
Prokaryotic Cells
Eukaryotic Cells
Similarities
Cell Membrane
Cytoplasm
Ribosomes
Cell wall and Flagella (same name, made differently)
Differences
Cytoskeleton (prokaryotic have a cytoskeleton precursor
that helps them keep their shape
Nucleus
DNA in cytoplasm
DNA in Nucleus
Eukaryotic Cells: Plants and Animals
Plant Cells
Animal Cells
Similarities
Cell Membrane
Cytoplasm
Ribosomes
Nucleus
Mitochondria
ER (Endoplasmic Reticulum)
Golgi Apparatus
Cytoskeleton
Peroxisomes (aids in digestion, breaks down toxic
substances; like lysosomes EXCEPT do not go to Golgi
apparatus and have many different enzymes)
Differences
Chloroplast
Central Vacuole
(contains watery
solution of enzymes
that degrade and
recycle molecules and
organelles)
Plasmodesma
(communication
between plant cells
nutrients and
biochemicals travel
through these to
adjacent cells)
Cell Wall
Centrosomes
(important in cell
division)
Lysosomes (contains
enzymes (lyse) to break
down food particles,
capture bacteria, worn
out organelles and
debris)
Cilia (increase surface
area)
Gap Junction (channels
between two cells =
allows exchange of ions,
nutrients, and other
small molecules)
Tight Junction (glues
neighboring cells
together = impermeable
barrier between them =
