NEET Questions / Botany / Sexual Reproduction in Flowering Plants / Post Fertilization Structure And Events
Syngamy is the process in which
Male gamete fuses with female gamete
Pollen tube enter into the ovule through micropyle
Pollen tube enter into the ovule through chalaza
Vegetative cell and tube cell fuse
Occurrence of more than four spores from a spore mother cell is called
Polysiphony
Polyspermy
Polyspory
Polyembryony
Identify the characters with reference to the plant in which eight nucleated embryo sac was first studied by strasburger.
I – Micropyle, chalaza and funiculus are arranged in the same vertical line
In the ovule.
II – presence of both unisexual and bisexual flowers in the same plant.
III – Filiform apparatus helps in conduction of food materials from
Endosperm to egg apparatus.
IV – Long funiculus coils like a watch spring around the ovule.

Because of marked climatic variations, plants growing near the sea shore do not produce annual rings
The age of the plant can be determined by its height
Healing of damaged tissue is because of the activity of sclerenchyma cells
