organelles :
specialised subcellular structures found within
living cells
cells : basic structural unit of organisation
tissues :
group of cells with similar structures , working together to perform specific functions
organs
:
group of tissues , working together to perform specific functions
organ system : group of organs with similar functions ,
work together to perform body functions

mitochondria respiration occurs here i releases energy chloroplasts , cell wall ,
chloroplasts :
light is absorbed and changed Into food vacuole
ribosomes :
proteins are synthesized here
wall supports cell
cell animals everything

and keeps it in shape : -
vacuole :
full of cell sap , maintains shape chloroplasts , cell wall ,
cell membrane :
controls substances going in and out vacuole
cytoplasm :
chemical reactions takes place here
, Specialised cells
•
cells which has developed certain characteristics in order to perform particular functions
•
cells specialise by undergoing differentiation
↳ difference atlon : when a cell gains new structures for it to be suited to Its function
•
difference cited cells important in a multicellular organism to perform specialised functions
↳ but often loses the ability to make new copies of themselves
•
thus multicellular organisms must retain some un specialised cells to replenish cells when needed
↳ ( stem cells ) e.g .
epithelial , fat , nerve , muscle , bone ,
etc .
