What is the function of the Synergids?

The synergid cells direct pollen tube growth toward the female gametophyte, and facilitate the entrance of the tube into the embryo sac. Once the pollen tube enters the synergid cell, its growth is arrested, the tip of the tube breaks, and two sperm cells are released.

What is the function of Synergids Class 9?

The main functions of the synergids are: The chemical substances secreted by the filiform apparatus of the synergids helps in attracting the pollen tube towards the embryo sac. The degenerating synergids act as a site of the discharge of the male gametes of the pollen tube.

What are Antipodals cells?

antipodal cells The three haploid cells in the mature embryo sac of flowering plants that are situated at the opposite end to the micropyle.

What are Synergids?

Hint: Synergids is one of two small cells found near the egg in a flowering plant’s mature embryo sac. They aid in the process of fertilization. The two Synergid cells serve as the source of the signals that guide the pollen tube. The nutritional center is made up of three antipodal cells.

What is the function of Synergids in the embryo sac?

What is the function of the antipodal cells in the female gametophyte?

The antipodal cells of the female gametophyte sometimes acquire glandular properties, as may cells of the nucellus surrounding the embryo sac. In some species the embryo itself develops a suspensor that penetrates the tissues of the parent sporophyte and acts as an absorbing organ.

What is the function of Synergids Class 10?

They act as a shock absorber at the time of the entry of the pollen tubes in the embryo sac. Sometimes, synergids act as haustoria which helps in the transportation of nutrients.

What is the function of antipodal cell in embryo sac?

– Antipodal cells play a very important role in the embryo sac. They are responsible for the supply of nutrition for the whole gametophyte and also take part in the supply of nutrition during embryo formation.

What is the function of Nucellus?

Nucellus makes the most of the ovule. It encloses the embryo sac. They have abundant food reserves and therefore act as nutritive tissues for the embryo in some plants.

What is antipodal in biology?

Definition of antipodal (Entry 2 of 2) : any of three haploid cells in most angiosperms that are grouped at the end of the embryo sac farthest from the micropyle. — called also antipodal cell.

What happens to the Synergids?

After the process of fertilization, the synergids disintegrate. Synergids are short-lived cells present near the egg in the matured embryo sac of a flowering plant. These cells become disorganized and disappear soon after the fertilization of the egg.

What is the function of Synergids Class 12?

The function of synergids is to basically attract and guide the pollen tube to the megagametophyte.
