LAB SESSION 2: CELL STRUCTURE AND
FUNCTION. EXAM QUESTIONS AND
ANSWERS (VERIFIED AND UPDATED)
All living organisms are composed of - ANS Cells
___ are responsible for all structural and functional properties of a living organism - ANS Cells
Border of the cell, controls passage of material in and out - ANS Phospholipid Bilayer
Facilitate the movement of ions and molecules across the membrane; penetrates the
membrane - ANS Integral Proteins
Loosely attach to cell membrane surfaces, performing crucial roles in cell signaling; adheres to
one face of the membrane - ANS Peripheral Proteins
