Morphological Features
- Fruit Characteristics:
Avocados are large berries with a leathery skin that can range in color from green to nearly black when fully ripe. The fruit is distinguished by its creamy, pale green flesh and a large, singular seed at its center. The rich, buttery texture and subtle nutty flavor make it a favorite ingredient in many dishes. - Tree Structure:
