Parte dos

Eukaryotic cell appearance

Eukaryotic cell characteristics

Membrane bound organelles/endomembrane system/75% phospholipids

Cytoskeleton of eukaryotic cell

Microtubules/Intermediate filaments/Microtubules (Actin/Keratin/Tubulin)

Actin filaments are for what

Contraction/relaxation

Amoeboid movement is possible due to

actin filaments

Eukaryotic cell’s DNA strands are separate or together?

Separate strands

Difference between eukaryotic/prokaryotes DNA strands

prokaryotes are circular

What does the eukaryotic cell’s nucleolus make?

RNA

What is Golgi apparatus

Protein modification/packaging

Endoplasmic Reticulum

Changes polypeptide/smooth/synthesize proteins

Endoplasmic Reticulum example

Pre-pro insulin → pro-insulin → insulin

Mitochondria

Organic molecule oxidation. Has own DNA and 70s ribosomes w/inner and outer membrane. Makes ATP

Centrosomes

Made of tubulin/divide into centrioles

What eukaryotic cells DONT have walls

protozoa/animal cells

What eukaryotic cells DO have walls

plants/fungi/algae

Plants cell wall

cellulose

Fungi’s cell wall/what does membrane have

Chitin

Algae’s cell wall

Pectin

Protists made of

algae and protozoa

Fungi made of

molds/mushrooms/yeasts

plants made of

angiosperms/gymnosperms

Animals made of

fish/reptiles/birds/mammals/amphibians

Protozoa characteristics

thin cell wall/flexible

Pectin characteristics

Rigid w/cellulose

Cellulose characteristics

thick/inflexible w/chlorophyll A in the chloroplast 

Are animal cells unicellular or multicellular?

Multicellular

Chitlin characteristics

has ergosterol membrane

What ribosomes?

80s

Lysosomes contain what

Hydrolytic enzymes

Peroxisomes do what

oxidize toxins/waste (BURN BABY BURN)
