Pectic polysaccharides
Vacuoles
• Cheaply produce large cell • Multiple function including storage
Digestion ,pH and ionic homeostasis, microbial defense ,sequestration of toxic compounds and pigmentation
• (Structurally): middle lamella ,primary wall second wall
• Polysaccharide :Cellulose micro fibrils (scaffold), Hemicelluloses cross link the Cellulose micro fibrils ,and the cellulose and hemicelluloses complex is embedded by pectin gel
The nucleus and its nuclear pore complex
Peroxisomes
Mitochondrion
• Resemble prokaryotes • Like all plastids ,are semi
autonomous ,posses the genetic machinery to make some of its protein • Cell power supplied station
• Cell wall is borne at cell plate and cell enlargement dependent on combination activities of endglycosidase ,endotransglycosidse ,and expansin
