Question

Given below are two statements:
Statement (I): The growth of guava fruits follow a single sigmoid curve
Statement (II): The fruits undergo extensive cell division during the first few week immediately following fertilization
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are true.
• B. Both Statement (I) and Statement (II) are false.
• C. Statement (I) is true but Statement (II) is false.
• D. Statement (I) is false but Statement (II) is true.

Hint:

Fruit Growth Curves: Single sigmoid (one rapid growth phase), Double sigmoid (two rapid growth phases with a lag in between). Guava typically shows a double sigmoid curve.
Early Fruit Development: The first stage after fertilization is dominated by cell division, setting the stage for later cell expansion and fruit growth.

Answer 1

The Correct Option is D

Step 1: Guava fruit growth follows a double sigmoid curve, not a single sigmoid curve, so Statement (I) is false.
Step 2: The first phase after fertilisation is marked by rapid cell division, confirming Statement (II).
Step 3: So (I) false, (II) true.
Step 4: Correct option: \( \boxed{\text{Statement (I) is false but Statement (II) is true}} \).
