Choose the correctly matched pair.a)Mitosis - Four new cellsb)Meiosis ...
- Option A: Mitosis - Four new cells
Incorrect. Mitosis results in the formation of two identical daughter cells, not four. Each daughter cell has the same number of chromosomes as the mother cell.
- Option B: Meiosis - Two new cells
Incorrect. Meiosis leads to the creation of four new cells, each with half the number of chromosomes compared to the mother cell, not just two.
- Option C: Golgi apparatus - Storage and packaging of substances
Correct. The Golgi apparatus is responsible for the storage, modification, and packaging of substances manufactured in the cell.
- Option D: Nucleus - Manufacture of proteins
Incorrect. The nucleus directs the life processes of the cell and contains genetic material, but the actual manufacture of proteins occurs in the ribosomes, which are either free in the cytoplasm or attached to the endoplasmic reticulum.
Thus, the correctly matched pair is Option C: (c) Golgi apparatus - Storage and packaging of substances.

Understanding the Correctly Matched Pair: Golgi Apparatus
The correct answer to the matched pair question is option 'C' — Golgi apparatus - Storage and packaging of substances. Here’s a detailed explanation:
What is the Golgi Apparatus?
- The Golgi apparatus, also known as the Golgi body or Golgi complex, is a vital organelle found in eukaryotic cells.
- It is primarily involved in modifying, sorting, and packaging proteins and lipids that are synthesized in the endoplasmic reticulum (ER).
Functions of the Golgi Apparatus:
- Modification of Proteins: The Golgi apparatus modifies proteins by adding carbohydrate groups to them, a process known as glycosylation.
- Sorting and Packaging: Once modified, proteins are sorted and packaged into vesicles. These vesicles can either be secretory vesicles that transport proteins to the cell membrane for secretion or lysosomes that contain digestive enzymes.
- Storage: The Golgi apparatus acts as a storage site for proteins and lipids before they are sent to their final destinations.
Why Other Options are Incorrect:
- Mitosis - Four New Cells: Mitosis results in two genetically identical daughter cells, not four.
- Meiosis - Two New Cells: Meiosis actually produces four genetically diverse cells, not two.
- Nucleus - Manufacture of Proteins: The nucleus contains the genetic material and is responsible for transcription, while ribosomes (found in the cytoplasm or on the rough ER) are the sites of protein synthesis.
In conclusion, option 'C' accurately describes the primary role of the Golgi apparatus in cellular function, making it the correct matched pair.
