(i) Describe the endosperm development in coconut.
(iii) Why is tender coconut considered a healthy source of nutrition?
(iii) How are pea seeds different from castor seeds with respect to endosperm?
(i) In coconut, endosperm formation is nuclear type. The primary endosperm nucleus undergoes nuclear division without cell wall formation.
(ii) Soft coconut is an endosperm. It is rich in nutrients like fats, proteins, carbohydrates, minerals, vitamins, etc. Hence, it is considered as a healthy source of nutrition.
(iii) Depending upon the presence or absence of endosperm, the seeds having copious amounts of endosperm tissue are called albuminous seeds (e.g. wheat, maize, castor, coconut, sunflower, etc.) and seeds in which the endosperm is used ( up are non-albuminous (e.g. beans, pea and groundnut).
In some seeds, remains of nucellus are present, called as perisperm (e.g. in blackpepper and beet). The monocot and dicot seeds are named due to the number of cotyledons, a have seed. The major differences between monocot and dicot seeds are:
