✿Human cell:
☞Human cell is eukaryotic cell.
☞Contains 80s ribosomes in cytoplasm and 70s ribosomes in mitochondria.
☞Have membrane bound organells.
☞Cell wall and chloroplast are absent.
☞Their are various types of cells in human depending upon structure, morphology and function of cell.
☞Three main types are;
☞1) Red blood cell:
These are biconcave cells becomes enucleate on maturation to store more haemoglobin.
haemoglobin gives red colour to RBC and responsible for gaseous exchange.
They don't have cell organells on maturity , so in absence of mitochondria they perform anaerobic respiration.
☞2) White blood cell:
There are many types of WBC's which are transparent and help in immune system.
☞3) Platelets:
These are not true cells but formed by fregments of megakaryocytes.
