Peas are legumes and belong to the Fabaceae family. Common edible peas include garden peas, sugar peas and snow peas. Mature pea pods develop within 50 to 70 days from planting and contain multiple peas, or ovules.
The shell of the pea pod is the ovary wall. This protects the ovules and provides a safe environment for them to grow and mature. Pea pods are dehiscent, meaning they have a seam that runs along both sides that can split open.
The inside of a pea pod is known as the locule. Within the locule are small stems, called funiculi, which connect the ovules to the inner wall of the pea pod. Funiculi also deliver nutrients to the ovules.
Pea pod ovules develop into seeds, or peas. The ovule contains the primary root, hypocotyl and plumule. These structures will eventually produce the first root of a new pea seedling and the first stem and leaves.
