Below is the 2014 Waec Specimen for Biology
1.
SPECIMEN A= YOUNG MAIZE PLANT

*SOIL REQUIREMENT= well drained loam and silt loam with fine tilth.

*METHOD OF PROPAGATION= It is propagated by seed

*planted manually, mechanically

*VARIETIES/TYPES: dent,flint,sweet,flour,pop corn

*CLIMATIC REQUIRMENT= (20degreec-30degreec)

*RAINFALL OF 760mm-1520mm per annum is used

SPECIMEN B=MALE FLOWERS OF MAIZE PLANT

*It’s also called=”TASSEL”,is failrly compact and much branched. the
main axis carries spikelets and these consist of one SESSILE and
PEDICEL. each flower is composed of an oval,concave lemma enclosing a
membranous palea with the three stamens and two lodicules. when the
flower matures, the anthers are exposed. the anthers may be purple,pink
or yellow.

SPECIMEN C= FEMALE FLOWERS OF MAIZE PLANT

*It’s also known as the COB or EAR. Is has a modified lateral branch
derived from an auxilliary bud of the main stem. the husk of the female
inflorescence is formed from modified leaves and this gives protection
to the flowers and the developing seeds. the ovary is surmounted by a
long style, the silk of which emerges from the top of the husk.
pollination is by means of wind and gravity,the grains are more pointed
at the end where it is attached to the cob. they are made up of ovary,
style and stigma.
