🌿T2: cells
3.2.1 and 3.2.2 cell structure
what is the structure of eukaryotic cells?
what is the function of the cell membrane?
-cell membrane controls what goes in and out of the cell
what is the function of the nucleus?
-contains the organisms genetic info and controls the cells activities
and manufactures rRNA and ribosomes
-nuclear envelope, nuclear pores, nucleoplasm, chromosomes,
nucleolus
what is the function of the mitochondrion?
-site of aerobic respiration
-responsible for production of ATP
what is the function of the chloroplasts?
T2: cells 1
, -carry out photosynthesis
-the grana are stacks of up to 100 disk- like structures called
thylakoids- chlorophyll present in here
-the stroma is a fluid filled matrix, contains other structures like like
starch grains
what are the adaptations of the chloroplasts?
-the granal membranes provide SA which aids photosynthesis
-contain both DNA ribosomes so they can easily manufacture
proteins needed for photosynthesis
what is the function of the rough endoplasmic reticulum?
-has ribosomes on outer surface
-provides large SA for synthesis of proteins and glycoproteins
-provide a pathway for the transport of materials
what is the function of the smooth endoplasmic reticulum?
-no ribosomes on outer surface
-synthesise, store and transport lipids
-synthesise, store and transport carbohydrates
what is the function of the golgi apparatus?
-produces vesicles which move to the surface and fuse with the
membrane and release their contents to the outside
-add carbohydrates to proteins to form glycoproteins
-produce secretory enzymes
-secrete carbohydrates
