Question

(a) Draw a diagrammatic sectional view of a mature anatropous
ovule and label the following parts in it:
(i) that develops into seed coat.
(ii) that develops into an embryo after fertilization.
(iii) that develops into an endosperm in an albuminous seed.
(iv) through which the pollen tube gains entry into the embryo sac.
(v) that attaches the ovule to the placenta.
(b) Describe the characteristic features of wind pollinated flowers.

Answer 1

Integument forms the seed coat.

Egg forms embryo after fertilization.

Polar nuclei forms endosperm after fertilization in albuminous seed.

Pollen tube gains entry through micropyle.

Funiculus attaches the ovule with placenta.

Wind pollinated flowers have long filament, long style, numerous pollen grains, sticky stigma and non coloured flowers.

Explanation:

• A mature anatropous ovule is a ovule which is seen in maximum plants.

• Integument is the part of a fertilized ovule that forms the seed coat.

• Egg is the part of mature ovule that forms embryo after fertilization.

• Polar nuclei is the part of mature ovule that forms endosperm after fertilization in albuminous seed.

• Before fertilization, the Pollen tube gains entry through micropyle of the anatropous ovule.

• Both before and after fertilization, Funiculus attaches the ovule with placenta.

• Wind pollinated flowers have wind as the agent of pollination.

• They have long filament, long style, numerous pollen grains, sticky stigma and non coloured flowers.
