Answer 1

Answer:

There are 6 types of ovules:- orthotropous (erect), anatropous (inverted), hemi-anatropous, campylotropous (body curved), amphitropous (both body and embryosac curved) and circinotropous(funiculus coiled around the ovule).

Answer 2

Answer:

1. Orthotropous ovule
2. Anatropous ovule
3. Campylotropous ovule

Explanation:

Orthotropous ovule

• Micropyle, chalaza and funicules are on same vertical line.
• It is also called as straight ovule.
• Example :- Polygonum

Anatropous ovule

• Body of ovule bends back along side the side of funiculus (180°).
• Because of this curvature, the micropyle lies closer to funiculus.
• Also called as Inverted ovule.
• Example :- Sunflower

Campylotropous ovule

• Ovule is placed right angles of the funiculus.
• Body bends and micropyle comes closer to funiculus.
• Embryo sac of the ovule is slightly curved.
• Example :- Leguminosae
