Orthotropous ovule

Orthotropous ovule is a botanical term that refers to a type of ovule found in most flowering plants. It is characterized by an upright position, with the micropyle (the opening through which the pollen enters) and the chalaza (the base where the ovule is attached to the ovary wall) at opposite ends of the ovule.

Orthotropous ovules are commonly found in many plant species and play a vital role in sexual reproduction. They allow for the development of seeds after successful fertilization.

Sample Sentences:

1. The orthotropous ovule of the lily flower developed into a healthy seed after fertilization.

2. The botanist carefully examined the orthotropous ovule under the microscope to study its internal structures.

3. In most angiosperms, such as roses and apples, the ovary contains numerous orthotropous ovules.
