Consider the following pairs. S.  No Cell Organelle Function 1. Endoplasmic Reticulum as channels for the transport of materials (especially proteins) between various regions of the cytoplasm 2. Golgi Apparatus responsible for packaging proteins into vesicles prior to secretion 3. Lysosomes they break down excess or worn-out cell parts   Which among the above is/are correct pairs? Correct Answer 1, 2 and 3

The correct answer is 1, 2 and 3.

• The cellular components are called cell organelles which include both membrane and non-membrane bound organelles, present within the cells.
• They coordinate and function efficiently for the normal functioning of the cell.

Key Points

• Endoplasmic Reticulum
  • ​It is a large network of membrane-bound tubes and sheets.
  • There are two types of ER– rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER).
  • The manufactured proteins are then sent to various places in the cell depending on need, using the Endoplasmic Reticulum.
  • The smooth endoplasmic reticulum helps in the manufacture of fat molecules, or lipids, important for cell function.
  • It functions as channels for the transport of materials (especially proteins) between various regions of the cytoplasm. Hence, Statement 1 is correct.
• Golgi Apparatus
  • ​It consists of a system of membrane-bound vesicles (flattened sacs) arranged approximately parallel to each other in stacks called cisterns.
  • Its functions include the storage, modification and packaging of products in vesicles.
  • They are responsible for packaging proteins into vesicles prior to secretion. Hence, Statement 2 is correct.
• Lysosomes
  • ​These are membrane-bound sacs filled with digestive enzymes.
  • These are a kind of waste disposal system of the cell.
  • These help to keep the cell clean by digesting any foreign material as well as worn-out cell organelles.
  • Lysosomes may burst and the enzymes digest their own cell. Therefore, lysosomes are also known as the ‘suicide bags’ of a cell. Hence, Statement 3 is correct.
