Eucaryote Cell Structure and Function
I. Eucaryote Anatomy
A. Internal Structures
1. Cytoplasmic membrane
similar to procaryote
contain sterols, e.g. cholesterol
pinocytosis
phagocytosis
2. Cytoplasmic matrix
numerous organelles
a) endoplasmic reticulum (ER)
rough ER
smooth ER
b) Golgi apparatus
c) lysosomes: synthesized by ER and Golgi apparatus
d) ribosomes
e) mitochondria
f) chloroplasts
3. Nucleus
membrane-bound
chromatin
nuclear pores
nucleolus
B. External Structures
1. Cell wall
simplier than procaryote
2. Cilia/flagella
thicker and more complex than procaryote flagella
cilia: 5-20 µm long
flagella: 100-200 µm long (9+2 pattern)
