The shoot apical meristem in a dicot embryo is located
between the two cotyledons
within the root apex
around the suspensor
in the endosperm
The main function of cotyledons in a seed is to
provide protection to the radicle and plumule
help in seed germination
supply food to the young embryo
store food materials
After fertilisation the seed coats develop from
integuments
chalaza
nucellus
embryo sac
Flowers emit fragrance
to purify air
to attract insects
to drive away flies
to perform all the above mentioned functions
A corolla of five petals with vexillary aestivation is said to be
ligulate
bilabiate
personate
papilionaceous
Tetradynamous condition of the androecium is a characteristic feature of the family
Brassicaceae
Fabaceae
Poaceae
Malvaceae
Cross- pollination is favoured by
self - sterility
dichogamy
herkogamy and heterostyly
all the above
Meiotic divisions in an ovule take place in
megaspore
megaspore mother cells
archesporium
In angiosperms, the embryo sac represents
male gametophyte
young sporophyte
female gametophyte
future fruit
Fertilization of the egg takes place inside the
anther
stigma
pollen tube
