Endosperm polyembryony is type of

Options

A. Adventitive polyembryony
B. True polyembryony
C. False polyembryony
D. Gametophytic polyembryony.

Answer

To determine the type of endosperm polyembryony, we need to analyze the options provided and understand the definitions of each type of polyembryony.

### Step-by-Step Solution:

1. **Understand Polyembryony**: Polyembryony refers to the occurrence of multiple embryos developing from a single fertilized ovule. This can happen through various mechanisms.

2. **Analyze the Options**:
- **Option A: Adventive Polyembryony**: This type occurs when embryos develop from diploid cells of the ovule, such as the integument or nucellus. It does not involve the endosperm, so this option is incorrect.

- **Option B: True Polyembryony**: In this case, multiple embryos develop from a single embryo sac. This can occur when one zygote divides to form multiple embryos, and it involves the endosperm providing nourishment to the developing embryo. This is the correct answer as it directly relates to endosperm polyembryony.

- **Option C: False Polyembryony**: This type involves the formation of embryos from different embryo sacs within the same ovule. Since it does not involve the endosperm, this option is also incorrect.

- **Option D: Gametophytic Polyembryony**: This type involves the formation of embryos from haploid cells (like synergids) and diploid cells (like the zygote). This does not relate to endosperm, making this option incorrect as well.

3. **Conclusion**: After analyzing all options, the correct answer is **Option B: True Polyembryony**, as it involves the development of embryos in relation to the endosperm.

### Final Answer:
Endosperm polyembryony is a type of **True Polyembryony**.
