parenchyma 
these cell do not loose their protoplasm during maturation
generally isodiametric
cells are thin walled cell wall made up of cellulose
cells are closely packed with no intercelllular space or have small intercellular space 
location : roots,stem,leaves,flowers,fruits,seeds
function : storafe of food ,photosynthesis ,secretion

collenchyma
cells maybe oval,spherical,polygonal
intercellular space is absent 
location below epidermis in dicot it is absent in monocot 
function mechanical support ,synthesis of food
