Question

In 82% of angiosperm families, ovule is

• A. Anatropous
• B. Orthotropous
• C. Amphitropous
• D. Circinotropous

Answer 1

The correct option is A Anatropous

In gymnosperms, the ovules lie uncovered on the scales of the cone. In angiosperms, one or more ovules are enclosed by the ovary (the portion of the carpel or female reproductive organ). Each ovule is attached by its base to the stalk (funiculus) that bears it.

Based on the form and position of the ovule they are classified as orthotropous are simplest and primitive type ovules stand out straight into the cavity of the ovary; campylotropous ovules are at right angles to the funiculus; anatropous are most common type ovules are directed back toward the funiculus or completely inverted ovule turned back 180 degree on its stalk. Intermediate forms also occur

So, the correct answer is 'Anatropous'
