Which cell organelles are known as the cell's post office? 

The correct answer is the Golgi apparatus. Key Points

• Golgi apparatus is known as the cell's post office because it packages and distributes molecules (proteins and lipids) to different parts of the cell and outside the cell.
• It modifies, sorts, and packages the molecules in vesicles and sends them to their intended destinations.
• The Golgi apparatus is composed of stacks of flattened membranous sacs called cisternae, which are responsible for carrying out the aforementioned functions.
• The Golgi apparatus is present in eukaryotic cells, which include animal and plant cells.

Additional Information

• The nucleus is known as the control center of the cell, as it contains genetic material (DNA).
  • It is responsible for regulating cell growth, division, and metabolism.
• Ribosomes are responsible for synthesizing proteins in the cell,
  • They are either free in the cytoplasm or attached to the endoplasmic reticulum.
• Plastids are organelles found only in plant cells and are responsible for functions such as photosynthesis, storage, and pigment synthesis.
  • Plastids include chloroplasts, chromoplasts, and leucoplasts.
