The suspensor originates from the basal cell formed during the first division of the zygote.
It plays a crucial role in pushing the embryo into the endosperm for better nutrient access.
The length and structure of the suspensor can vary among different plant species.
Although it is essential in early development, it typically degenerates as the embryo matures.
In some plants, suspensors produce hormones like gibberellins that promote embryonic growth.
