Synergids are cells found in the female reproductive system of flowering plants. The IPA phonetic transcription of this word is /sɪˈnəːdʒɪdz/. The "s" at the beginning is pronounced as a "s" sound, followed by the "i" which is pronounced as an "ih" sound, then the "n" is pronounced as an "n" sound. The "e" is pronounced as an "ee" sound, followed by the "r" pronounced as an "r" sound. The "g" is pronounced as a "j" sound, followed by another "i" pronounced as an "ih" sound. The "d" is pronounced as a "d" sound, and the "z" is pronounced as a "z" sound.
Synergids are specialized cells found in the ovule of flowering plants that play a fundamental role in the process of plant reproduction and fertilization. These cells are located within the embryo sac, which is the female gametophyte of the plant.
Synergids are typically present in pairs and are located adjacent to the egg cell or oosphere. Their primary function is to guide the pollen tube to the egg cell during fertilization. The synergids produce attractants that help to direct the pollen tube's growth towards the ovule, ensuring successful pollination and subsequent fertilization.
Additionally, synergids also have a crucial role in the protection and nutrition of the developing embryo. They secrete proteins and metabolites that nourish and support the growth of the developing embryo, promoting its development into a viable seed.
Synergids are characterized by their unique structure and features. They have cellular extensions called filiform apparatus, which extend into the micropyle, a small opening at the tip of the ovule. The filiform apparatus aids in communication with the pollen tube and allows for the exchange of signals and nutrients between the synergid cell and the growing pollen tube.
In summary, synergids are specialized cells within the ovule of flowering plants that facilitate fertilization by attracting and guiding the pollen tube to the egg cell. They also provide nutritional support to the developing embryo, ensuring the successful production of viable seeds.
The term "synergids" is derived from the combination of two Greek words: "syn" meaning "together" or "with", and "ergon" meaning "work" or "function". Therefore, "synergids" refers to cells that work together or have a cooperative function. In the context of plant reproduction, synergids are two specialized cells found in the ovule of a flower. They are involved in the fertilization process and play a critical role in guiding the pollen tube to the embryo sac for successful double fertilization.
