Question

typically With a neat labelled diagram describe the parts of a
angiospermic ovule.
For 10 Marks in points ​

Answer 1

Explanation:

• The main part of ovule is nucleus which is enclosed by two intugement leaving an opening called micropyle.
• The ovule is attached to the overy wall by the stalk known as funiculas.
• chalaza is the basail part.
• The embryo sac contain 7cells and 8nucleus which is located within the centre.
• Three cell at the micropylar end form egg apparatus.
• Three cells at the chalaza end form antipodal cells.
• The remaining two nuclie are called polar nuclie.
• In egg apparatus two are egg cells and another one is synergids.

Answer 2

Answer:

Explanation:

Funicle is the connecting point between the ovule and ovary.

Hilum is the structure that connects the ovule and funicle.

Integuments are the covering layer that protects the developing embryo.

Embryo sac is the structure that contain ovum and polar nuclei for fusion and embryo development.

Micropyle is the tiny opening of ovule which helps in germination of mature ovule by absorbing the moisture.
