Why is parathenogensis considered as a speical mode of reproduction in plants?

Explanation

### Step-by-Step Solution:

1. **Definition of Parthenogenesis**: Parthenogenesis is a form of asexual reproduction where an egg develops into an embryo without fertilization. In plants, this means that the female gametophyte (the egg) can develop directly into an embryo.

2. **Comparison with Normal Reproduction**: In typical sexual reproduction, fertilization occurs when a male gamete (sperm) fuses with a female gamete (egg), resulting in the formation of a zygote. This zygote then develops into an embryo. In contrast, parthenogenesis skips the fertilization step entirely.

3. **Significance of Parthenogenesis**: The ability of an egg to develop into an embryo without fertilization is what makes parthenogenesis a special mode of reproduction. It allows for the production of offspring in the absence of male gametes, which can be advantageous in certain environmental conditions where mates are scarce.
