WebAt the chalazal end of the ovule are three antipodal cells. Fertilization involves a pollen tube entering the ovule through the micropylar opening and releasing its sperm cells. An attractant released by the synergid cells guides the pollen tube to the female gametophyte ( Escobar-Restrepo et al., 2007 ). WebThe chalazal end has 3 cells called the antipodal cells. Lastly, there is a large central cell which consists of two polar nuclei. Suggest Corrections 1 Similar questions Q. Read …

Web4 apr. 2024 · Complete answer: Synergids – They are also known as the helper cells or the Co-operative cells. They are present in the micropylar end. They are two in number. These cells have a micropylar nucleus and a chalazal vacuole. They lack a cell wall at their micropylar end due to the presence of the filiform apparatus. During the development of the embryo sac inside a flowering plant ovule, the three cells at the chalazal end become the antipodal cells. Chalazogamy [ edit ] In most flowering plants, the pollen tube enters the ovule through the micropyle opening in the integuments for fertilization (porogamy).
