ORTHOTROPOUS Meaning and Definition

1. Orthotropous is an adjective that describes the position of an ovule within a flower. It refers to a specific orientation where the ovule is straight and symmetrical, with its axis aligned with the stalk or placenta. This anatomical arrangement allows for an easy passage of the pollen tube during fertilization.

   Orthotropous ovules are typically found in higher plants, particularly in angiosperms, which are flowering plants. They represent a common and basic form of ovule structure and are often considered the most primitive type.

   The term "orthotropous" originates from the Greek words "ortho," meaning straight, and "tropous," meaning turned. It signifies the straight orientation of the ovule within the flower.

   The key characteristics of orthotropous ovules include a straight axis, the micropyle (a small opening for the entry of the pollen tube) located at one end, and the chalaza (a basal region where the ovule attaches to the stalk or placenta) located at the other end. The integuments, protective layers of tissue that surround the ovule, are usually evenly distributed and symmetrical.

   While orthotropous ovules are considered the ancestral condition, many variations have evolved among different plant species. These variations may include curved or tilted axes, asymmetrical integuments, or modifications in the position or development of the micropyle. However, orthotropous ovules remain an essential component in understanding the reproductive structures and processes of flowering plants.

2. In botany, noting an ovule in which the nucellus is a straight with base toward the placenta.
