Eukaryotes vs Prokaryotes Flashcards
DNA contained in a nucleus surrounded by a nuclear envelope of two membranes
Eukaryotes
No true nucleus. DNA lies free in cytoplasm
Prokaryotes
Linear DNA associated with histone proteins to form chromosomes
Eukaryotes
Circular DNA not associated with proteins. Separate loops of DNA called plasmids may be present
Prokaryote
Cell wall, if present, made from cellulose (plants, algae) or chitin (fungi)
Eukaryotes
Cell wall containing peptidoglycan
Prokaryotes
Endoplasmic reticulum present and may contain attached ribosomes
Eukaryotes
No endoplasmic reticulum or associated organelles (e.g golgi apparatus)
Prokaryotes
Contains double membrane bound organelles, mitochondria and chloroplasts (in plants, algae)
Eukaryotes
No double membrane bound organelles
Prokaryotes
Many types of cell organelle present (compartmentalisation and division of labour)
Eukaryotes
Few types of organelle present
Prokaryotes
Larger (80S) ribosomes (22nm in diameter)
Eukaryotes
Smaller (70S) ribosomes (18nm in diameter)
Prokaryotes
If present, undulipodia have 9 + 2 arrangement of microtubules and are surrounded by plasma membrane
