save my exams structure of prokaryotic and vs eukaryotic and viruses

Question 1

how dopro differ from euk

Answer 1

A cytoplasm that lacks membrane-bound organelles
Their ribosomes are structurally smaller (70 S) in comparison to those found in eukaryotic cells (80 S)
No nucleus (instead they have a single circular DNA molecule that is free in the cytoplasm and is not associated with proteins)
A cell wall that contains murein (a glycoprotein)
Plasmids
Capsules
Flagellum

Question 2

what are plasmids

Answer 2

small loops of DNA that are separate from the main circular DNA molecule
Plasmids contain genes that can be passed between prokaryotes

Question 3

whats a slime capsule for

Answer 3

helps to protect bacteria from drying out and from attack by cells of the immune system of the host organism

Question 4

flagellum

Answer 4

long, tail-like structure that rotate, enabling the prokaryote to move (a bit like a propeller)
Some prokaryotes have more than one

Question 5

prokartoic vs eukaryotic

Answer 5

pro is smaller
dna is not w histones
70s vs 80s ribsomes
no memb bound vs memb bound
peptidoglycan walal vs cellulose

Question 6

structure of virus

Answer 6

non-cellular infectious particles
A nucleic acid core (their genomes are either DNA or RNA, and can be single or double-stranded)
A protein coat called a ‘capsid’
envelope formed usually from the membrane-phospholipids of a cell they were made in
ribosomes) to produce new viral particles
