Question

Chalazal pole is present​

Answer 1

Answer:

In plant ovules, the chalaza is located opposite the micropyle opening of the integuments. It is the tissue where the integuments and nucellus are joined. ... During the development of the embryo sac inside a flowering plant ovule, the three cells at the chalazal end become the antipodal cells.

Answer 2

Answer:

• The chalaza is found in plant ovules opposite the micropyle aperture of the integuments. The integuments and nucellus are connected by this tissue. The three cells at the chalazal end evolve into the antipodal cells as the embryo sac inside a flowering plant ovule develops.
• A variety of transcription factors control the specification and differentiation of female gametophyte cells, and auxin gradients affect the polarity of these cells.
• The nucellus is where the megaspore mother cell develops. After meiosis, the diploid megaspore mother cell divides into four haploid megaspores.
• In the embryo sac near the chalazal pole, there are antipodal cells. Typically, there are three of these.
• The central cell, which is located in the core of the embryo sac, is the largest cell in the ovule.
