continuous from outer membrane membrane of nuclear envelope
consists of cis face and trans face
produce lysosomes
involve in packaging, sorting and shipping of protein and lipid
has a flattened membranous sacs (cisternae)
which is FALSE about lysosomes
it is single membrane-bound sac
contain hydrolytic enzymes
can digest worn out cell
originate from nucleus
What is mean by autophagy
digest food taken via phagocytosis
digestion of worn out organelle
digestion of entire cells
self destruction
which of the following are TRUE about mitochondria
consists of inner and outer membrane
the infolding inner membrane is called cristae
site for cellular respiration
contain its own DNA
what is mean by semiautonomous organelle
because the shape is rod
because it can be found in eukaryotic cells only
able to replicate freely because it has its own DNA
because it can synthesise energy

suspended freely in cytosol
attach to smooth endoplasmic reticulum
attach to nuclear membrane
attach to rough endoplasmic reticulum
what is the function of centrioles?
site for photosynthesis
help in organise assembly of microtubules during cell division
digest worn out organelle
synthesise protein
where centrioles can be found
centre of the cell
in centrosome
in nucleus
what is the differences between smooth ER and rough ER
Rough ER has ribosomes but not in smooth ER
Rough ER is for protein synthesis but smooth ER for lipid synthesis
Rough ER is in animal cell but not smooth ER
