Correct Option
The correct option is A-4, B-3, C-1, D-2
Explanation
Eukaryotic cells contain specialized membrane-bound structures called organelles, each performing distinct metabolic functions essential for cellular survival and efficiency. The coordination between these organelles ensures processes like synthesis, detoxification, and waste management occur seamlessly.- A. Ribosomes (Matches with 4): Ribosomes are minute particles consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They are the primary sites of protein manufacture (synthesis), translating genetic code into amino acid chains.
- B. Smooth Endoplasmic Reticulum (SER) (Matches with 3): The SER is distinguished by the absence of ribosomes on its surface. It is responsible for the manufacture of fat molecules (lipids) important for cell function. Crucially, in the liver cells of vertebrates, the SER plays a significant role in the detoxification of many poisons and drugs.
- C. Lysosomes (Matches with 1): Lysosomes are membrane-bound sacs filled with digestive enzymes. They serve as the cell's waste disposal system by digesting foreign materials (such as bacteria and food) as well as worn-out cell organelles.
- D. Golgi Apparatus (Matches with 2): This organelle consists of a system of membrane-bound vesicles arranged in stacks. Its functions include the storage, modification, and packaging of products in vesicles. It is also involved in the formation of complex sugars from simple sugars.
Key Takeaway: Ribosomes synthesize proteins; the Smooth Endoplasmic Reticulum (SER) detoxifies poisons and synthesizes lipids; Lysosomes digest cellular waste; and the Golgi Apparatus modifies and packages cellular products.
