Word: Ventral Placentation

Part of Speech: Noun

Definition: Ventral placentation is a term used in botany (the study of plants) to describe a specific way that seeds (ovules) are attached inside a plant's ovary. In this type of placentation, the seeds grow along the inner wall of the ovary, specifically along the ventral suture, which is the line where the two halves of the ovary meet.

Usage Instructions:

• Context: This term is mostly used in scientific discussions about plant anatomy and reproduction. It is not commonly used in everyday conversation.
• When to use: Use "ventral placentation" when discussing how a particular plant species develops its seeds or when studying plant reproductive structures.

Example:

• "In the pea plant, ventral placentation allows the seeds to develop efficiently along the inner wall of the ovary."

Advanced Usage:

• You might encounter this term in academic articles or textbooks on botany or plant physiology. Understanding it can help you grasp how different plants reproduce and develop their seeds.

Word Variants:
