Pollination
-
Even in absence of pollinating agents seed-setting is assured inCommelina produces cleistogamous flowers, which never open.
Their anthers and stigma lie close together, so self-pollination and seed-set are assured even without pollinators.
Fig depends on wasps, Zostera on water and Salvia on insects.
Endosperm
-
The coconut water and the edible part of coconut are equivalent toCoconut water from tender coconut is free-nuclear endosperm, made up of thousands of nuclei.
The surrounding white kernel, the edible part, is cellular endosperm.
So both are endosperm.
Pollen grain
-
An organic substance that can withstand environmental extremes and cannot be degraded by any enzyme isThe exine of the pollen grain is made of sporopollenin, one of the most resistant organic materials known.
It withstands high temperature, strong acids and alkali, and no enzyme that degrades it is known so far.
That is why pollen grains are well preserved as fossils.
That is every question in Sexual Reproduction in Flowering Plants for this filter.
