FUNCTIONS OF TESTA AND MICROPYLE:
A minute opening in the ovule of a seed plant through which the pollen tube usually enters. A pore in the membrane covering the ovum of some animals through which a spermatozoon can enter.
The testa of higher plant seeds protects the embryo against adverse environmental conditions. Its role is assumed mainly by controlling germination through dormancy imposition and by limiting the detrimental activity of physical and biological agents during seed storage.
