Question

Some points on hemitropous Ovule......​

Answer 1

This ovule is also called as horizontal ovule because the body of ovule is present in horizontal position on the funiculus.

• This type of ovules are also known as Hemianatropous Ovule.
• This is the intermediate type between ortho and anatropous ovules.
• Micropyle & chalaza both are present at the same line but micropyle is situated away from hilum.

Answer 2

Answer:Ovule type (Figure 9.33B) is based primarily on the curvature of the funiculus and nucellus/female gametophyte. An anatropous ovule is one in which curvature during development results in displacement of the micropyle to a position adjacent to the funiculus base; this is the most common ovule type of the angiosperms and is presumed to be ancestral. An orthotropous [atropous] ovule is one in which no curvature takes place during development; the micropyle is positioned opposite the funiculus base. (An ovule somewhat intermediate in curvature between anatropous and orthotropous is sometimes termed hemitropous or hemianatropous.) A campylotropous ovule type is one in which the nucellus is bent only along the lower side. An amphitropous ovule is one in which the nucellus is bent strongly along both upper and lower sides, with a lower “basal body.
