Which of the following is false in angiosperms

Options

A. Egg cell - haploid
B. Megaspore - diploid
C. Pollen grain - haploid
D. Synergid - haploid.

Answer

To determine which statement is false regarding angiosperms, we will analyze each option provided in the question step by step.

### Step 1: Understand Angiosperms
Angiosperms are flowering plants that reproduce through seeds enclosed within a fruit. They have distinct structures such as the embryo sac and pollen grains, which play crucial roles in reproduction.

### Step 2: Analyze Each Option
1. **Xl - haploid**:
- The Xl refers to the female gamete found in the embryo sac.
- The embryo sac is a haploid structure, meaning it contains a single set of chromosomes.
- This statement is **true**.

2. **Megaspore - diploid**:
- The megaspore is formed from the megaspore mother cell, which is diploid.
- However, the megaspore itself is haploid as it is produced through meiotic division (reduction division), resulting in four haploid megaspores.
- Therefore, this statement is **false**.

3. **Pollen grain - haploid**:
- Pollen grains are the male gametes of angiosperms and are also haploid structures.
- This statement is **true**.

4. **Synergid - haploid**:
- Synergids are cells found in the embryo sac and are haploid.
- This statement is **true**.

### Step 3: Conclusion
After analyzing all the options, we find that the statement about the megaspore being diploid is false. Therefore, the correct answer to the question is that the statement "Megaspore - diploid" is false in angiosperms.

### Final Answer
The false statement in angiosperms is: **Megaspore - diploid**.
