Fruit Types and Descriptions
- Pome: A fruit type characterized by an outer fleshy layer surrounding a papery core.
- Samara: A type of fruit featuring a small dry seed equipped with one or two wing-like structures facilitating wind dispersal.
- Berry: Defined as a fruit where the entire ovary is fleshy and juicy throughout, lacking a hard stony layer.
- Drupe: This fruit has an outer fleshy layer along with a hard woody inner layer encasing the seed.
Key Biological Concepts
- Gametes: The reproductive cells in plants, including sperm and egg cells.
- Animal Dispersal: A seed dispersal mechanism utilized by plants like sandbur, where seeds attach to animals or clothing to travel to new locations.
- Aggregate Fruit: A type of fruit formed from a single flower that has multiple pistils, resulting in several small fruits clustered together.
- Nectar: A sweet and watery liquid produced by flower structures, attracting pollinators.
- Radicle: The embryonic part of a plant that develops into the root system, crucial for anchoring and nutrient absorption.
