Ultrastructure of nucleus

Image
  Ultrastructure of Nucleus 🟦 Introduction A Nucleus is made up of 4 part *Nuclear membrane or karyotheca *Nucleolus *Nuclear sap or nucleoplasm *Chromatin reticulum or nuclear reticulum 🟦 Nuclear membrane or karyotheca *Karyotheca is a bilayered membrane that surrounded nucleus 🟡 structure- 1)made up of lipoprotein 2) this is the trilaminar membrane 3) diameter 62-90 Å 4) distance between to memories 100-500 Å 5) intermediate space between two membrane is called perinuclear cisternae or perinuclear space. 6) the pores presentation nuclear membrane called nuclear pores 7) diameter of the pores 300-500 Å 8) ribosome and endoplasmic reticulum is is attached to it outer membrane of the nuclear membrane 🟡 Nuclear pore- ~nuclear pore is a complex structure. ~part of the pore is diaphragm, septum, plug or nucleoplasmin and various annuli. ~annulus is a circular part that covers the nuclear pores. ~a pore with annulus called pore complex. ...

Cell wall of eukaryotic cell/plant cell

Cell wall of eukaryotic cell/plant cell (part 1) in details 1) Position Outside the plant cell a thick, rigid,permeable constant coat, made up of cellulose Only present in plant cell and prokaryotic cell. The eukaryotic animal cell has no cell wall 2) origin Golgi body and endoplasmic reticulum help in cell wall formation as studying in Electronic microscope 3) Process of formation of cell wall   *Cell plate form in in the telophase stage of cell division between two daughter nucleus on the middle region by storing a pectin like carbohydrate named phragmoplast *After that during physical and chemical change middle lamella form *On middle lamella various chemical substance store to form cell wall Structure of cell wall 1)   Middle lamella ·     Intracellular fluid between two plants cell ·     Made up of mainly calcium and magnesium pected and protein ·    In udan tissue ...
