The fertilization of the egg occurs in the ovary.

Maize bears anemophilous flower.

Date palm is a dioecious plant.

Fruit and seed of the maize plant grows into a 'GRAIN'.

The part of the embryo between the cotyledons and the embryonic root (Radicle) is called Hypocotyl.

Micro-propagation is the practice of rapidly multiplying stock plant material to produce a large number of progeny plants, using modern plant tissue culture methods. It is being used widely for propagating forest trees of economic importance.

The offspring produced by the vegetative propagation are genetically identical.

The mega-spore mother cell and micro-spore mother cell, both divide meiotically.

The remaining part of nucellus is called perisperm.

In plants only a sporophyte produces spores.

The secondary nucleus of angiosperm after fertilization is 3x. The second sperm cell fuses with both central cell nuclei, producing a triploid (3x) cell. As the zygote develops into an embryo, the triploid cell develops into the endosperm, which serves as the embryo's food supply.

In double fertilization, the male gamete fuses with the egg cell and another male gamete with two polar nuclei.

In angiosperms, the embryo sac represents female gametophyte.

The ovule can be compared to megasporangium.

After fertilization, fruit is derived from ovary.
