Outermost layer, non living ,rigid Found in bacterial cells, fungal cells and plant cells. Permeable Made up of cellulose (in bacteria- peptidoglycans, in fungus- Chitin)
Semi fluid matrix present between cell membrane and nuclear membrane It has various living cell inclusions called cell organelles and non living substances called Ergastic substances
ER is a network of membrane bound tubular structures in cytoplasm It extends from cell membrane to nuclear membrane it exists as flattened sacks called Cisternae, unbranched tubules and oval vesicles There are two types of ER, ROUGH ER and SMOOTH ER. Helps in intracellular transportation It provides mechanical support to cytoplasmic matrix It he...
