Select the incorrect statement w.r.t tapetum. (a) Cells of tapetum are polyploid. (b) Amoeboid tapetum provides ubisch bodies which helps in ornamentation of exine. (C) Tapetal cells show increase in their DNA content. (d) Innermost layer of anther surrounds the sporogenous tissue. (e) Glandular tapetum secretes sporopollenin, pollenkit and compatibility proteins

Options

A. (b) & (e)
B. (b), (d), (e)
C. (a), (c), (e)
D. Only (b)

Answer

To solve the question regarding the incorrect statement about tapetum, we will analyze each option step by step.

### Step 1: Analyze Statement (a)
**Statement:** Cells of tapetum are polyploid.
**Analysis:** This statement is true. The cells of the tapetum undergo endomitosis, which leads to polyploidy. Therefore, this statement is correct.

**Hint:** Remember that polyploidy in tapetal cells is due to endomitosis, which is a type of nuclear division.

### Step 2: Analyze Statement (b)
**Statement:** Amoeboid tapetum provides ubisch bodies which help in ornamentation of exine.
**Analysis:** This statement is incorrect. The amoeboid tapetum does not provide ubisch bodies; instead, it primarily provides nutrition through its degeneration. Ubisch bodies are associated with glandular tapetum, not amoeboid. Thus, this statement is false.

**Hint:** Focus on the function of amoeboid tapetum; it is more about nutrition than ornamentation.

### Step 3: Analyze Statement (c)
**Statement:** Tapetal cells show an increase in their DNA content.
**Analysis:** This statement is true. The DNA content of tapetal cells increases due to processes like endomitosis and the presence of polytene chromosomes. Therefore, this statement is correct.

**Hint:** Consider the reasons for DNA content increase in tapetal cells, such as endomitosis.

### Step 4: Analyze Statement (d)
**Statement:** Innermost layer of anther surrounds the sporogenous tissue.
**Analysis:** This statement is true. The tapetum, which is the innermost layer of the anther, surrounds the sporogenous tissue. Thus, this statement is correct.

**Hint:** Visualize the structure of the anther to understand the arrangement of layers.

### Step 5: Analyze Statement (e)
**Statement:** Glandular tapetum secretes sporopollenin, pollen kit, and compatibility proteins.
**Analysis:** This statement is true. The glandular tapetum does secrete sporopollenin, which is a major component of the pollen wall, as well as pollen kit and proteins that assist in pollen-stigma compatibility. Therefore, this statement is correct.

**Hint:** Remember the roles of glandular tapetum in pollen development and compatibility.

### Conclusion
After analyzing all the statements, we find that the incorrect statement is **(b)**: "Amoeboid tapetum provides ubisch bodies which help in ornamentation of exine."

### Final Answer
The incorrect statement with respect to tapetum is **(b)**.
