Select the wrong statements about the collenchyma:

Options

A. The collenchyma occurs in layers below the epidermis in dicotyledonous stem
B. It is always found continuous homogenous layers
C. Theses can assimilate food when they contain chloroplasts
D. Intercellular spaces are generally absent

Answer

To determine the wrong statements about collenchyma, let's analyze the characteristics of collenchyma step by step.

### Step 1: Understand the location of collenchyma
- **Statement**: Collenchyma occurs in layers below the epidermis in dicotyledon stems.
- **Analysis**: This statement is **correct**. Collenchyma is typically found just beneath the epidermis in dicotyledonous plants.

### Step 2: Examine the structure of collenchyma
- **Statement**: Collenchyma is always found as a continuous homogeneous layer.
- **Analysis**: This statement is **incorrect**. Collenchyma can be found in patches as well as in continuous layers.

### Step 3: Assess the function of collenchyma
- **Statement**: Collenchyma cells can assimilate food when they contain chloroplasts.
- **Analysis**: This statement is **correct**. When collenchyma cells have chloroplasts, they can perform photosynthesis and thus assimilate food.

### Step 4: Check the intercellular spaces in collenchyma
- **Statement**: Intercellular spaces are generally absent in collenchyma.
- **Analysis**: This statement is **correct**. Collenchyma cells typically have very little to no intercellular spaces due to their closely packed nature.

### Step 5: Review the composition of collenchyma
- **Statement**: Collenchyma consists of cells that are much thickened at the corners due to the deposition of cellulose, hemicellulose, or pectin.
- **Analysis**: This statement is **correct**. The thickening at the corners is a characteristic feature of collenchyma cells.

### Conclusion
The only wrong statement about collenchyma is that it is always found as a continuous homogeneous layer. Therefore, the correct answer is that the wrong statement is the one that claims collenchyma is always found as a continuous homogeneous layer.

### Final Answer
The wrong statement about collenchyma is: "It is always found as a continuous homogeneous layer."
