The correct Answer is:
To fill in the blank in the given statement, we need to identify the structure that is a defining feature of eukaryotic cells. ### Step-by-Step Solution: 1. **Identify the Type of Cell**: The question specifies eukaryotic cells. Eukaryotic cells are characterized by having a true nucleus and membrane-bound organelles. 2. **Recognize the Key Feature of Eukaryotic Cells**: The most distinguishing feature of eukaryotic cells is the presence of a nucleus. Unlike prokaryotic cells, which do not have a membrane-bound nucleus, eukaryotic cells have a well-defined nucleus that contains their genetic material. 3. **List Other Organelles**: The question mentions several organelles found in eukaryotic cells, such as the endoplasmic reticulum (ER), Golgi complex, lysosomes, mitochondria, microbodies, and vacuoles. These are all membrane-bound structures that perform specific functions within the cell. 4. **Fill in the Blank**: Based on the above points, the blank can be filled with "nucleus". Therefore, the complete statement reads: "Besides the nucleus, the eukaryotic cells have other membrane-bound distinct structures called organelles like the endoplasmic reticulum (ER), the Golgi complex, lysosomes, mitochondria, microbodies, and vacuoles." ### Final Answer: "Besides the **nucleus**, the eukaryotic cells have other membrane-bound distinct structures called organelles like the endoplasmic reticulum (ER), the Golgi complex, lysosomes, mitochondria, microbodies, and vacuoles." ---

Go through the following statements (i) In human beings, the membrane of the erythrocyte has approximately 52 percent lipids and 40 percent proteins (ii) Lipids are arranged within the membrane with the hydrophobic tails towards the outer side and the polar head towards the inner side. (iii) As the polar molecules cannot pass through the non- polar lipid bilayer, they require a carrier protein of the membrane to facilitate their transport across the membrane (iv) The endomembrane system includes endoplasmic reticulum, Golgi complex, lysosomes and peroxisomes Find out the wrong peroxisomes :

Assertion : The endomembrane system includes endoplasmic reticulum (ER), Golgi complex, lysosomes and vacuoles. Reason : Mitochondria, chloroplast and peroxisomes are not the part of endomembrane system because their functions are coordinated with the same.
