Which of these events is/are NOT TRUE for an apple fruit?

Options

A. only 1
B. only 2
C. only 2 and 4
D. only 2,3 and 4

Answer

To determine which events during fruit formation are NOT TRUE for an apple fruit, we can analyze each of the listed events step by step:

1. **The egg cell is fertilized by a male gamete.**
- This event is true for apple fruit formation. In flowering plants, fertilization occurs when a male gamete (from pollen) fertilizes the egg cell within the ovule. This is a crucial step in the formation of seeds.

2. **The thalamus withers away.**
- This event is NOT true for apple fruit formation. In many fruits, including apples, the thalamus (the thickened part of the stem that supports the flower) does not wither away; instead, it often contributes to the structure of the fruit.

3. **The ovules form seeds.**
- This event is true for apple fruit formation. After fertilization, the ovules develop into seeds. This is a standard process in the development of fruits.

4. **The ovary develops into the fleshy fruit.**
- This event is true for apple fruit formation. The ovary of the flower develops into the fleshy part of the fruit after fertilization, which is characteristic of apples.

Based on this analysis, the event that is NOT TRUE for apple fruit formation is:

**Answer:** The thalamus withers away (Event 2).
