2.1 Cell Structure & Organisation

Cell membrane

controls movement of substances in & out of the cell

Cytoplasm

site of all reactions

Nucleus

regulates processes, contains DNA

Ribosomes

site of protein synthesis

Mitochondria

site of aerobic respiration

(cellulose) cell wall

provides structure for plant

Chloroplast

site of photosynthesis

Permanent vacuole

filled with cell sap to keep cell turgid

Small vacuole

holds nutrients/waste

What is a bacteria cell wall made out of?

peptidoglycan

Bacteria have circular loops of DNA. They can also have extra circles that are called..

plamids

Rough endoplasmic reticulum (RER)

site of protein production and protein transport in the cell

Vesicles

transports proteins

Where are ribosomes found in the cell?

RER, vesicles

Prokaryotes

singled cell organisms with no nucleus

Eukaryotes

multi cellular organisms with nucleus
