Which of the following is incorrect match for angiosperms?

Options

A. Egg cell - Haploid
B. Megaspore - Diploid
C. Pollen grain-Haploid
D. Synergid - Haploid

Answer

To determine which of the following is an incorrect match for angiosperms, we need to analyze each option provided in the question.

1. **Egg Cell**: The egg cell is indeed haploid (1n). It is produced in the ovule and is involved in fertilization with the pollen grain.

2. **Megaspore**: The megaspore is produced from the megasporocyte (megaspore mother cell), which is diploid (2n). However, after meiosis, the megasporocyte produces four megaspores, which are haploid (1n). Therefore, stating that the megaspore is diploid is incorrect.

3. **Pollen Grain**: Pollen grains are also haploid (1n). They develop from the microspores produced in the anthers of the flower.

4. **Synergid**: Synergids are haploid (1n) cells that are part of the female gametophyte and are formed from the mitotic divisions of the haploid megaspore.

Based on this analysis, the incorrect match is:

**Megaspore - Diploid** (it should be haploid).

Thus, the answer to the question is **Option B: Megaspore (Diploid)**.
