how many chromosomes are there in a maize (corn) embryo cell nucleus as compared to a maize (corn) endosperm cell nucleus?

Sagot :

Two third chromosomes are there in a maize (corn) embryo cell nucleus as compared to a maize (corn) endosperm cell nucleus.

Maize and sorghum (Sorghum bicolor) both have 20 chromosomes (2n = 20). Maize endosperm is a large storage organ that accounts for 80-90% of the mature kernel dry weight. The mature maize kernel is the result of a coordinated developmental process that includes both the embryo and the endosperm. Endosperm development is prioritized in relation to overall kernel maturation. The endosperm is a triploid tissue made up of two sets of maternal chromosomes and one set of paternal chromosomes.

Over the course of 50-60 days, the maize grain grows from a fertilized ovule to a mature kernel. The developing kernel contains maternal tissues, such as the pericarp and nucellus, as well as tissues produced by double fertilization, such as the diploid embryo and triploid endosperm.
