The Function of Cell Membrane Passive Transport:It moves along the concentration difference and the potential difference,does not need energy,and transports passively. Active Transport:The transport process of matter molecules and ions from low concentration to high concentration needs energy

The Function of Cell Membrane Active Transport: The transport process of matter molecules and ions from low concentration to high concentration needs energy. Passive Transport: It moves along the concentration difference and the potential difference, does not need energy, and transports passively

Organelles Mitochondrion Oxidation energy supply Lysosome Important digestive organs in cells. Ribosome The mRNA was translated into protein. Endoplasmic Reticulum The scaffold for nucosme attachment. protein transport channels. Golgi Complex Material transport. Microfilament Polymerized from globular actin. Microtubule It's about movement,support and transportation. Centriole Exist in pairs,perpendicular to each other

Organelles Nuclear Envelope Ribonsome Ribonsome SER RER

Organelles Rough Endoplasmic Reticulum(RER):The particles attached to the RER are ribosomes,which are the sites of protein synthesis and participate in the production of more membranes. Smooth endoplasmic reticulum(SER):There is no ribosome in the smooth endoplasmic reticulum,but there are many active enzymes embedded in the membrane.The most important function is to synthesize lipids,including lipids,phospholipids and sterols

Organelles Free ribosomes synthesize proteins retained in the cytoplasm,such as structural proteins in the membrane. Ribosomes attached to the endoplasmic reticulum synthesize exocrine proteins,which are then transported to the smooth endoplasmic reticulum to form secretory vesicles,which are transported to the Golgi apparatus for processing and discharge
