Chromosome number in the edible part of coffee seed

Coffee is an important crop that is widely consumed around the world. The edible part of coffee seed is the endosperm, which is the tissue that surrounds the embryo and provides it with nutrients. The endosperm is triploid, which means it has three sets of chromosomes, one from the female parent and two from the male parent.

Explanation

Coffee plants have a diploid chromosome number of 22 in their somatic cells. This means that they have two sets of chromosomes, one from the female parent and one from the male parent. However, the edible part of the coffee seed, which is the endosperm, is triploid. This means that it has three sets of chromosomes, one from the female parent and two from the male parent.

The triploid nature of the endosperm is due to a process called double fertilization, which is unique to flowering plants. In double fertilization, two sperm cells from the pollen grain fertilize the female gamete, resulting in the formation of a triploid endosperm and a diploid embryo.

The triploid nature of the endosperm is important because it contributes to the flavor and quality of the coffee bean. The endosperm is rich in oils and other compounds that give coffee its distinctive aroma and taste.

Conclusion

In conclusion, the chromosome number in the edible part of the coffee seed, which is the endosperm, is triploid. This means that it has three sets of chromosomes, one from the female parent and two from the male parent. The triploid nature of the endosperm is important for the flavor and quality of the coffee bean.

The edible part seed of coffee after fertilization therefore it is diploid 2n in nature though endosperm. is also present
