happy new year sir.pleaseeeee.
You have said that Endoplasmic Reticulum carries certain materials throughout the cell, that's why it is called transport mechanism. Does it carry blood? Or food? I can't find the answer. Can you please tell me what it is?

Secretory proteins, mostly glycoproteins, are moved across the endoplasmic reticulum membrane.
I have doubts. How can I get them answered?

  1. STRUCTURE OF CELL


  2. The parts of cell are as follows: Cell wall PLasma membrane or cell membrane Nucleus .Cutoplasm Endoplasmic Reticulum Golgi Apparatus Lusosomes Mitochondria PLastids .Vacuole


  3. Endoplasmic reticulum The Large network of membranous sheets and tubes is called endoplasmic reticulum. They are filled with fluids and carries materials throughout the cell due to which it is also called transport system of the cell. Endoplasmic reticulum It transports materials betwseen the regions of cytoplasm or between the cytoplasm and nucleus. It also provides a surface for some biochemical activities of cell. I can be classified into buso types: RER (Rough Endoplasmic Reticulum) SER (Smooth Endoplasmic Reticulum)


  4. - The RER appears rough under a microscope as it is Lined with ribosomes. Rough endoplasmic eticulum Nyckeus - The ribosomes manufactures the roteins which are then transported hroughout the cell by the Endoplasmic Reticulum. Nuclear envelope Nuclear pore Ribosomes Smooth endoplasmik reticulum - The SER appears smooth under microscope due to absence of ribosomes. It also manufactures fab molecules or Lipids that are important for proper functioning of cell and detoxyfies the poisons present in Liver Secretory Vesicle ysosome Golgi apparatus Plasma membrane cells of vertebrates.


  5. GOLGI APPARATUS The stacks of flattened membranous vesicles are called Golgi apparatus. It basically stores, packs and modifies the products in vesicles. It temporarily stores protein that moves out of 'the cell through' the vesicles of the Golgi apparatus. Golgi Apparatus It packs and transports the materialLs synkhesised in Endoplasmic Reticulum to ifferent targets inside and outside the cell


  6. LYSOSOMES The sac-like structures in a cell surrounded by membrane are called iysosomes. - They keep the cells clean by digesting and breaking the outside materials Like bacteria, food entering the cell or worn-out cell organelles into small pieces. They can digest these organic materials due to the presence of strong digestive enzymes that can break down organic compounds. Therefore, lysosome is also known as a suicide sac. Many scientists believe that Lysosomes are not present in plavt cells and their function of lysosomes in' plants performed by vacuole. is
