Answer

To solve the question, we need to fill in the blanks for each of the four statements based on our understanding of plant morphology and physiology. Let's break it down step by step.

### Step 1: Analyze the first statement
**Statement:** In Limnophila heterophylla, the lamina of submerged leaves is very much dissected while the lamina of aerial leaves is entire. This variation in the form of lamina is referred to as ______.

**Solution:** This variation is referred to as **environmental heterophylly**. Environmental heterophylly occurs when plants exhibit different leaf forms based on environmental conditions, such as being submerged in water versus being exposed to air.

### Step 2: Analyze the second statement
**Statement:** Potato tubers, when exposed to light, turn green due to the increased production of a glycoalkaloid named ______.

**Solution:** The glycoalkaloid produced is called **solanine**. When potato tubers are exposed to light, they produce solanine, which can be toxic in high amounts.

### Step 3: Analyze the third statement
**Statement:** In ______, ovary arises from the bottom of the cup-shaped thalamus and androperianth arises from the rim of the cup-shaped thalamus.

**Solution:** This is characteristic of the plant **Prunus**. In Prunus, the ovary is situated below the thalamus, which is referred to as a hypogynous arrangement.

### Step 4: Analyze the fourth statement
**Statement:** Underground stems can be differentiated from roots by ______ of axillary buds on the nodes.

**Solution:** Underground stems can be differentiated from roots by the **presence** of axillary buds on the nodes. This is a key feature that distinguishes stems from roots.

### Final Answers
1. Environmental heterophylly
2. Solanine
3. Prunus
4. Presence
