Well developed pith is found in

Options

A. monocot root and monocot stem
B. monocot stem and dicot root
C. monocot root and dicot stem
D. dicot root and dicot stem

Explanation

To find out where well-developed pith is found, we can analyze the characteristics of pith in different plant structures. Here’s a step-by-step solution to the question:

### Step 1: Understand what pith is
Pith is a type of tissue found in the stems and roots of plants. It is primarily made up of parenchyma cells, which are involved in storage and transport of nutrients.

### Step 2: Identify the types of plants
There are two main types of flowering plants: monocots and dicots. Monocots have one cotyledon, while dicots have two.

### Step 3: Examine pith in monocots
In monocot stems, the pith is generally absent. However, monocot roots do have a well-developed pith.

### Step 4: Examine pith in dicots
In dicot stems, there is a well-developed pith made up of parenchymatous and occasionally sclerenchymatous cells. Dicot roots also typically have a well-developed pith.

### Step 5: Combine the findings
From the analysis:
- Monocot roots have a well-developed pith.
- Dicot stems have a well-developed pith.
- Monocot stems do not have a well-developed pith.

### Conclusion
The well-developed pith is found in monocot roots and dicot stems.

### Final Answer
Well-developed pith is found in monocot roots and dicot stems.
