What's the difference between meroblast and nutritive?
Meroblast
Definition:
(n.) An ovum, as that of a mammal, only partially composed of germinal matter, that is, consisting of both a germinal portion and an albuminous or nutritive one; -- opposed to holoblast.
Example Sentences:

(2) During meroblastic cleavage, and continuing in the early blastula, zebrafish blastomeres divide rapidly and synchronously.

(5) The meroblastic egg of the teleost, Fundulus heteroclitus, was studied electrophysiologically from cleavage to mid-gastrula stages.
(6) Meroblast formation was effected by clefts originating from the parasite plasmalemma and by fusion of vacuoles with each other.
Nutritive
Definition:
(a.) Of or pertaining to nutrition; as, the nutritive functions; having the quality of nourishing; nutritious; nutrimental; alimental; as, nutritive food or berries.
Example Sentences:
(1) Nutritionally rehabilitated animals had similar numbers of nucleoli to control rats.
