BUT IS JUST A GUIDE TO BIOLOGY
PRACTICAL. IT WILL HELP YOU TO STUDY YOUR BIOLOGY PRACTICAL. THEY ARE
ASSUMED OR LIKELY QUESTIONS AND
ANSWERS.



=====================


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,swee
t,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.
