In Pin us, many embryos are formed from single zygote, which is known as

Options

A. Simple polyembryony
B. Cleavage polyembryony
C. Polyspermy
D. Apogamy

Answer

To solve the question "In Pinus, many embryos are formed from a single zygote, which is known as," we need to analyze the options provided and understand the concepts related to embryo formation in plants.

### Step-by-Step Solution:

1. **Understanding the Question**: The question is asking about a specific phenomenon in Pinus where multiple embryos develop from a single zygote.

2. **Reviewing the Options**:
- **Option 1: Simple Polyembryony**: This term usually refers to the formation of one embryo from one fertilized egg. Since the question specifies multiple embryos, this option is incorrect.
- **Option 2: Polyembryony**: This term refers to the occurrence of multiple embryos developing from a single zygote. In the case of Pinus, this is the correct description as multiple embryos can arise from the cleavage of the zygote.
- **Option 3: Polyspermy**: This term refers to the fertilization of an egg by multiple sperm cells. This does not relate to the formation of multiple embryos from a single zygote, making this option incorrect.
- **Option 4: Apogamy**: This term refers to the formation of an embryo without fertilization. Since the question specifies that we are dealing with a zygote, this option is also incorrect.

3. **Identifying the Correct Answer**: After analyzing all options, the correct answer is **Option 2: Polyembryony**, as it accurately describes the phenomenon where multiple embryos develop from a single zygote in Pinus.

### Final Answer:
The correct answer is **Polyembryony**.
