Q

Dynamic continunity

A

membranes are interchangeable where material originally added in the endoplasmic reticulum may be transferred to another part of the endomembrane system by the movement of vesicles

16
Q

Why must the mitochondria and chloroplast be stable

A

Both of their inner and thylakoid membranes include membrane-embedded proteins that require a stable environment to function

Q

What do dynamic cytoskeletons and membranes allow for in eukaryotes

A

movements and endocytosis

19
Q

phagocytosis

Q

what is diverse about prokaryotic cells

A

how they take in molecules and foods

24
Q

Symbiosis

A

closely envolved association between two species

25
Q

Symbiont

A

an organism that lives in closely envolved association with another species.

26
Q

Endosymbiosis

A

Symbiosis where one partner lives inside the other

27
Q

Symbiosis theory of chlorplasts

A

symbiotic cyanobacteria became permanently incorporated into their host

28
Q

What is the double membrane
