Embryo development from synergid or antipodal cell is known as

Options

A. Apogamy
B. Apomixis
C. Amphimixis
D. Apospory.

Answer

To solve the question "Embryo development from synergid or antipodal cell is known as," we can follow these steps:

### Step 1: Understand the terms involved
- **Synergids** and **antipodal cells** are both haploid structures found in the embryo sac of flowering plants.
- **Synergids** are located near the egg cell and play a role in guiding the pollen tube for fertilization.
- **Antipodal cells** are located at the opposite end of the embryo sac and typically do not have a significant role in fertilization.

### Step 2: Identify the type of development
- The question asks about embryo development that originates from either synergids or antipodal cells.
- This process does not involve the typical fertilization process where a male and female gamete fuse.

### Step 3: Analyze the options
- **Apogamy**: This is a type of development where an embryo forms without fertilization, specifically from haploid cells like synergids or antipodals.
- **Apomixes**: This refers to seed development without fertilization, but it usually involves the formation of seeds from the ovule without the fusion of gametes.
- **Amphimixes**: This is the process of fertilization involving the fusion of male and female gametes.
- **Apospory**: This refers to the formation of gametophytes from sporophytic tissues.

### Step 4: Determine the correct answer
- Since the question specifically refers to embryo development from synergids or antipodal cells, the correct term is **apogamy**. This is because the embryo is developing from haploid cells without the fusion of gametes.

### Final Answer
The embryo development from synergid or antipodal cell is known as **apogamy**.
