What is the purpose of synergids in an ovule?

Synergids divide, producing megaspores.

Synergids divide, producing one large cell with eight haploid nuclei.

The function of synergids is unknown.

Synergids are the polar nuclei that share the cytoplasm of the large central cells of the embryo sac.

Synergids help to attract and guide the pollen tube to the embryo sac.

Verified step by step guidance

Understand the structure of the ovule: The ovule is a part of the plant's reproductive system, located within the ovary. It contains the embryo sac, which is crucial for fertilization.

Identify the role of synergids: Synergids are two specialized cells located at the micropylar end of the embryo sac, adjacent to the egg cell.

Explore the function of synergids: Synergids play a critical role in the fertilization process by helping to attract and guide the pollen tube towards the embryo sac, ensuring successful delivery of sperm cells to the egg cell.

Differentiate synergids from other cells: Unlike the other options provided, synergids do not divide to produce megaspores or a large cell with eight haploid nuclei, nor are they polar nuclei. Their primary function is related to guiding the pollen tube.

Conclude with the correct function: Based on the understanding of their role, the correct purpose of synergids is to assist in the attraction and guidance of the pollen tube to the embryo sac, facilitating fertilization.
