cells and cell techniques

What do prokaryotes not have that eukaryotes do

No membrane bound organelles

What’s the function of the cell wall

Prevents osmotic lysis

What’s the function of the mitochondria

Produces ATP from aerobic respiration for active processes

Function of rough endoplasmic reticulum

Synthesis packages and transports proteins

Function of Golgi body and vesicles

Golgi body modifies and packages proteins into vesicles which transport them

What’s a lysosome

Made by Golgi body and digests unwanted materia

5 structures that chloroplasts have

Lamella

Stroma- cytoplasm

Grant made o thylakoid membranes

Double envelope

Starch

3 structures mitochondria have separate

Cristae

Matrix-cytoplasm

Double membrane

Whats resolution

Minimum distance between two objects at which they can be seen as separate

Why do electron microscopes have a higher resolution than light

Electrons have a smaller wavelength than ight so the resolution is higher

Whats the difference between scanning EM and transmission EM

Scanning makes 3D images in colour
