Question

Identify the correct pair from the following:

• A. Tannin -- Pinus
• B. Resins -- Cassia
• C. Gum -- Neem
• D. Latex -- Acacia

Hint:

Important plant products:
• Resin \( \rightarrow \) Pinus
• Latex \( \rightarrow \) Rubber plant
• Gum \( \rightarrow \) Acacia, Neem

Answer 1

The Correct Option is C

Concept:
Plants produce different secretory substances such as:
• Gums
• Resins
• Latex
• Tannins These substances are economically and biologically important. Examples:
• Resins are commonly obtained from coniferous plants like Pinus
• Latex is obtained from rubber plants
• Gums are obtained from several trees including neem and acacia

Step 1: Understand plant secretory products.
Gums:
• Sticky plant exudates
• Produced after injury
• Used commercially Resins:
• Semi-solid substances
• Common in pine trees Latex:
• Milky fluid
• Found in rubber plant and papaya

Step 2: Analyze each pair carefully.
Option (A): Tannin -- Pinus
Pinus is mainly associated with resins, not tannins. Incorrect. Option (B): Resins -- Cassia
Cassia is not known for resin production. Incorrect. Option (C): Gum -- Neem
Neem tree produces gum. Correct. Option (D): Latex -- Acacia
Acacia is mainly known for gum production, not latex. Incorrect.

Step 3: Choose the correct answer.
Therefore, the correct pair is: \[ \boxed{\text{Gum -- Neem}} \] Hence, \[ \boxed{(3)\ \text{Gum -- Neem}} \]
