Select the incorrect match from the following.

Eukaryotic Cells
NEET
1

Rough endoplasmic reticulum – Site for protein synthesis

2

Golgi apparatus – Formation of glycoproteins

3

Lysosome – Has alkaline condition inside it

4

Chloroplast – Semiautonomous organelle

Solution:

Let's analyze each option:

(1) Rough endoplasmic reticulum (RER) is studded with ribosomes, which are the primary sites for protein synthesis. This statement is correct.

(2) Golgi apparatus is involved in the modification, sorting, and packaging of proteins and lipids. It plays a crucial role in the glycosylation of proteins to form glycoproteins and lipids to form glycolipids. This statement is correct.

(3) Lysosomes are membrane-bound organelles containing hydrolytic enzymes that are active at acidic pH (around 5.0). They maintain this acidic environment by pumping protons (H+) into their lumen. Therefore, lysosomes have an acidic condition inside, not alkaline. This statement is incorrect.

(4) Chloroplasts, like mitochondria, are semiautonomous organelles because they possess their own DNA, ribosomes, and can synthesize some of their own proteins. This statement is correct.

Thus, the incorrect match is option (3).
