Which of the following statements are correct
(i) When a fruit develop from the inflorescence, it si composite
(ii) Mesocarp is the edible part in apple
(iii) Gynobasic style is seen in Ocimum
(iv) Hypanthodium is a special type of inflorescence found in Euphorbia species

Options

A. a ,d correct
B. a ,c correct
C. a , b correct
D. b , d correct

Answer

To determine which of the statements are correct, let's analyze each statement one by one:

1. **Statement (i): When a fruit develops from the inflorescence, it is composite.**
- **Analysis:** Fruits can be classified into three categories: simple, aggregate, and composite (or multiple). A composite fruit develops from the entire inflorescence, meaning that multiple flowers contribute to the formation of the fruit. Therefore, this statement is **correct**.

2. **Statement (ii): Mesocarp is the edible part in apple.**
- **Analysis:** The pericarp of a fruit consists of three layers: epicarp, mesocarp, and endocarp. In the case of an apple, which is a false fruit, the edible part is derived from the thalamus, not the mesocarp. Thus, this statement is **incorrect**.

3. **Statement (iii): Gynobasic style is seen in Ocimum.**
- **Analysis:** The gynobasic style is characterized by the style arising from the base of the ovary. This type of style is indeed found in the genus Ocimum (basil). Therefore, this statement is **correct**.

4. **Statement (iv): Hypanthodium is a special type of inflorescence found in Euphorbia species.**
- **Analysis:** Hypanthodium is a type of inflorescence that resembles a fruit and is characterized by a fleshy, hollow structure. However, this type of inflorescence is unique to the Moraceae family, not Euphorbia. Euphorbia species have a different type of inflorescence known as Scyanthium. Thus, this statement is **incorrect**.

**Conclusion:**
The correct statements are:
- (i) When a fruit develops from the inflorescence, it is composite. (Correct)
- (iii) Gynobasic style is seen in Ocimum. (Correct)

**Final Answer: (i) and (iii) are correct.**
