(i) Mitochondria and chloroplasts possess small and circular non-histones DNA.
(ii) Mesosomes are extension of plasma membrane .
(iii) Quasi fluid nature of lipid enables flip flop movement of Proteins at specific place .
(iv) Components of endomembrane system associated with secretion , packaging of material and capble of digestion of several macro organic compounds .
From given , incorrect statement is / are

Options

A. i and iii
B. ii and iv
C. ii, iii and iv
D. iii

Answer

To determine which statements are incorrect, let's analyze each one step by step:

### Step 1: Analyze Statement (i)
**Statement**: Mitochondria and chloroplasts possess small and circular non-histone DNA.

**Analysis**: This statement is true. Both mitochondria and chloroplasts have their own DNA, which is circular and not associated with histone proteins, similar to bacterial DNA.

### Step 2: Analyze Statement (ii)
**Statement**: Mesosomes are extensions of the plasma membrane.

**Analysis**: This statement is also true. Mesosomes are indeed extensions of the plasma membrane in prokaryotic cells. They play roles in various cellular processes, including cell division and respiration.

### Step 3: Analyze Statement (iii)
**Statement**: Quasi fluid nature of lipid enables flip-flop movement of proteins at a specific place.

**Analysis**: This statement is incorrect. The fluid mosaic model describes the movement of proteins within the lipid bilayer as lateral movement, not flip-flop movement. Flip-flop movement refers to the movement of lipids between the two layers of the bilayer, which is rare and not a characteristic of protein movement.

### Step 4: Analyze Statement (iv)
**Statement**: Components of the endomembrane system are associated with secretion, packaging of material, and capable of digestion of several macromolecules.

**Analysis**: This statement is true. The endomembrane system includes structures like the endoplasmic reticulum, Golgi apparatus, and lysosomes, which are involved in secretion, packaging, and digestion of macromolecules.

### Conclusion
Based on the analysis:
- Statement (i) is true.
- Statement (ii) is true.
- Statement (iii) is incorrect.
- Statement (iv) is true.

Thus, the incorrect statement is **(iii)**.

### Final Answer
The incorrect statement is: **(iii)**.
