Q

Describe smooth endoplasm and rough endoplasm

A

Smooth endoplasm- produce steroids (lipid), breakdown toxins in liver, breakdown and synthesis cholesterol

Q

Describes 3 regions of nucleus

A

Nuclear membrane: barrier of nucleus, have nuclear pores- allow for exchange (cytoplasm=nucleus)

Nucleolus; contains one/more nucleoli , sites of ribosomes production

Chromatin; contains DNA/ protein, scattered throughout the nucleus
