In grass, when older die, new may develop form underground stem, same phenomenon can be observed in:
a) Strawberry
b) Mint
c) Eichhorni
d) Pistic

Options

A. Strawberry
B. Mint
C. Eichhorni
D. Pistic

Answer

To solve the question regarding the phenomenon observed in grass and its similarity to other plants, we can follow these steps:

### Step 1: Understand the Phenomenon in Grass
In grass, when older parts die, new plants can develop from an underground stem. This process involves the formation of runners, which are horizontal branches that grow parallel to the ground. At certain nodes on these runners, adventitious roots can develop, allowing new plants to arise.

### Step 2: Analyze the Options
Now, let's evaluate the options provided in the question:

- **a) Strawberry**: In strawberries, the modification is called a stolon. This is a horizontal branch that grows above the ground and can produce new plants at its nodes.

- **b) Mint**: Mint also produces runners similar to grass. These runners grow horizontally and can give rise to new plants at their nodes.

- **c) Eichhornia**: This plant forms a horizontal branch with nodes that produce new plants, but the structure is different from grass.

- **d) Pistia**: Pistia has offsets, which are similar to Eichhornia but differ from the grass-like runners.

### Step 3: Identify the Correct Answer
Since the question asks for a phenomenon similar to that of grass, we need to find a plant that produces runners in a manner akin to grass.

- **Mint** produces runners that are similar to the grass's underground stems, allowing new plants to develop in a comparable way.

Thus, the correct answer is **b) Mint**.

### Summary of the Solution:
The phenomenon of new plants developing from underground stems in grass is similar to that observed in **Mint**.
