Golgi Apparatus in Plant Cells

Golgi Apparatus in Plant Cells

• The Golgi apparatus (or Golgi complex) is a dynamic structure in plant cells, composed of stacks of flattened membrane sacs (cisternae), and a network of tubules and vesicles (trans Golgi network—TGN).
• Each stack is called a Golgi body or dictyosome.
• The Golgi apparatus has distinct regions:
  • The trans face is closest to the cell membrane.
  • The cis face is closest to the cell's center.
  • The medial cisternae are in between.
  • The trans Golgi network is part of the trans face.
• Inter cisternal elements (protein crosslinks) stabilize the cisternae.
• The Golgi plays a crucial role in producing and secreting complex polysaccharides (polymers of different sugars) and assembling the sugar chains (oligosaccharides) of glycoproteins.
• In plants, the Golgi body is vital for cell wall formation.
• Secretory vesicles, derived from the Golgi, carry the produced polysaccharides and glycoproteins to the plasma membrane.
• These vesicles then fuse with the plasma membrane and release their contents into the cell wall.
• Secretory vesicles can be smooth or have protein coats.
• Vesicles from the endoplasmic reticulum (ER) are generally smooth.
• Most vesicles from the Golgi have protein coats that assist vesicle formation.

Golgi apparatus ya xwendevî ya peyvan e ku di xelatên gülgîn de ye, bi awayek dinamik. Ev parçe, gavan û vesîklîyan çêdike û rola girîng li çêkirina polîsakarîdên pirr mjor dagirin. Di vê quizê de hûn destpêka xwendinê li ser Golgi aparatus û rolê wî di xelatên gülgîn de fêm dikin.
