Suspensor
from class: General Biology I Definition The suspensor is a structure in seed plants that connects the developing embryo to the nutrient-rich tissue of the seed. It helps in nutrient transfer and supports early embryonic growth.
congrats on reading the definition of suspensor . now let's actually learn it.
Predict what's on your test 5 Must Know Facts For Your Next Test 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. Review Questions What is the primary function of the suspensor in seed plants? How does the suspensor contribute to embryonic development? Does the suspensor persist throughout the entire lifecycle of a plant?
